Description

Catalytic reactor and catalytic reaction system utilizing electrical heating method

[0001] The present invention relates to a catalytic reactor and a catalytic reaction system. More specifically, the present invention relates to a catalytic reactor and a catalytic reaction system that perform heating electrically.

[0002]

[0003] A catalytic reactor is a device that uses a catalyst within the reactor to react reactants to produce a desired product. Representative processes utilizing catalytic reactors include reforming and cracking. Reforming and cracking reactions are mostly endothermic, which can lower the temperature within the reactor, thereby reducing catalytic activity. Therefore, reforming and cracking reactions require continuous heat supply to maintain operation within the target temperature range.

[0004] Typically, heat is supplied to the reactor and / or the outer walls of the channel containing the catalyst through combustion within the furnace. During this process, the fuel is combusted, releasing carbon dioxide. This can lead to environmental pollution and other issues. Furthermore, if heat transfer from the outer walls of the catalytic reactor to its interior is not smooth, endothermic reactions can cause a decrease in reactivity due to a drop in the reactor's core temperature.

[0005] Therefore, a catalytic reactor is required that does not reduce reactivity while minimizing negative impact on the environment.

[0006]

[0007] An object of the present invention is to provide a method for supplying a heat source to a catalytic reactor by electrical means instead of combustion.

[0008] An object of the present invention is to provide a method for effectively supplying a heat source to a catalytic reactor through an electrical method.

[0009] The above and other objects of the present invention can all be achieved by the present invention described below.

[0050]

[0051] Figure 1 is a schematic drawing of a catalytic reactor according to embodiments.

[0052] The catalytic reactor (100) according to the embodiments utilizes a catalyst to react reactants. At this time, the catalyst can promote the reaction of the target material by inducing a specific reaction at a predetermined temperature. The catalytic reactor (100) heats or cools its internal temperature to reach a predetermined temperature. Through this, the catalytic reactor (100) allows the catalyst to mediate the reaction.

[0053] At this time, the catalytic reactor (100) does not supply a heat source through combustion to prevent the generation of carbon dioxide. Instead, the catalytic reactor (100) converts electrical energy into heat and supplies a heat source internally. Thus, the catalytic reactor (100) according to the embodiments can utilize the catalyst while preventing environmental pollution.

[0054] To this end, the catalytic reactor (100) includes a reactor (120) and an electric heater (110). For example, 120 shown in FIG. 1 represents an outer wall of a reactor according to embodiments. In addition, the catalytic reactor (100) further includes a target catalyst (130) inside the reactor (120). However, the components of the catalytic reactor (100) according to embodiments are not limited thereto, and the catalytic reactor (100) may include only at least a portion of the components illustrated in FIG. 1 and / or may further include additional components in addition to the components illustrated in FIG. 1. A specific description of each component is as follows.

[0055] The reactor (120) houses a catalyst (130) therein. The reactor (120) provides an environment suitable for the catalyst (130) to mediate a reaction through heating or cooling. The reactor (120) may be formed, for example, with an outer wall containing a conductive material. The outer wall is a component that divides the inside of the catalyst reactor (100) and the outside of the catalyst reactor (100) and is a structure that allows the catalyst reactor (100) to maintain its shape. The conductive material includes, for example, a metal. The metal includes, for example, aluminum (Al), nickel (Ni), copper (Cu), platinum (Pt), gold (Au), silver (Ag), magnesium (Mg), titanium (Ti), etc. However, the material applicable to the outer wall of the reactor (120) is not limited thereto, and any material that allows current to flow may be applied to the outer wall of the reactor (120). Meanwhile, all parts of the outer wall of the reactor (120) may include a conductive material. However, only a portion of the outer wall of the reactor (120) may include a conductive material. Through this configuration, the reactor (120) evenly transfers heat from the outer wall to the interior of the reactor (120). Accordingly, the catalytic reactor (100) according to the embodiments solves the problem of reduced reactivity due to uneven heat transfer from the heat source.

[0056] An electric heater (110) supplies current to a reactor (120). For example, the electric heater (110) is connected to an outer wall of the reactor (120) and supplies current to the outer wall of the reactor (120). The electric heater (110) supplies current to the reactor (120), thereby generating resistive heat in the reactor (120). For example, the electric heater (110) generates resistive heat in an outer wall of the reactor (120) that includes a conductive material. Through this, the electric heater (110) can heat the reactor (120). Accordingly, the catalytic reactor (100) according to the embodiments provides a method for supplying a heat source to the reactor (120) without supplying a heat source by combustion.

[0057] The electric heater (110) includes any form capable of supplying electrical energy. The electric heater (110) can receive electrical energy from a sustainable energy source, such as solar or wind power, and supply it to the reactor (120).

[0058] The catalyst (130) is a material that mediates a reaction by the catalytic reactor (100) according to the embodiments. The catalyst (130) reacts at a predetermined temperature. The catalyst (130) is provided within the reactor (120). The catalyst (130) receives heat from the reactor (120) by an electric heater (110). For example, the catalyst (130) may receive heat from the outer wall of the reactor (120) heated by the electric heater (110). The catalyst (130) may reach a predetermined temperature as the temperature changes. Accordingly, the catalyst (130) mediates a reaction at a predetermined temperature.

[0059] Meanwhile, the catalytic reactor (100) according to the embodiments can supply a fluid (140) flowing along the inside of the reactor (120). The fluid (140) includes, for example, air, LNG, etc., and is, for example, an object having a flow. The fluid (140) flows, for example, in one direction (F) inside the reactor (120). For example, when the reactor (120) is formed in the shape of a pipe having a hollow interior and being formed in a longitudinal direction, the fluid (140) can be introduced into one side of the reactor (120) and discharged from the other side. The fluid (140) reacts with the catalyst. The fluid (140) may vary depending on the catalyst (130), or the catalyst (130) may vary depending on the fluid (140).

[0060] Through this configuration, the catalytic reactor (100) according to the embodiments provides a method for improving the reactivity of the catalyst (130) by evenly supplying a heat source internally while preventing environmental degradation. Below, a method for operating such a catalytic reactor (100) more efficiently will be described.

[0061]

[0062] Figure 2 is a schematic diagram showing a catalytic reaction system according to embodiments.

[0063] The catalytic reaction system (1000) according to the embodiments includes components for improving the efficiency of the catalytic reactor (100) described in FIG. 1. For this purpose, for example, the catalytic reaction system (1000) includes a catalytic reactor (100) and a processor (300). In addition, the catalytic reaction system (1000) may further include a sensor (200). Furthermore, the components included in the catalytic reaction system (1000) are not limited to the components illustrated in FIG. 2, and the catalytic reaction system (1000) may further include additional components in addition to the components illustrated in FIG. 2. In addition, the catalytic reaction system (1000) may be identical to the catalytic reactor (100). That is, all components included in the catalytic reaction system (1000) may be included in the catalytic reactor (100), and accordingly, the catalytic reactor (100) may perform all operations that the catalytic reaction system (1000) can perform.

[0064] The catalytic reactor (100) is identical or similar to that described in FIG. 1. In addition, various examples of the catalytic reactor (100) provided by the embodiments are described below in FIGS. 4 to 11.

[0065] The processor (300) controls all or part of the components included in the catalytic reaction system (1000). The processor (300) may be built into the catalytic reactor (100) and / or may communicate with all or part of the components included in the catalytic reaction system (1000) through a communication unit (not shown) to control the components. The processor (300) includes, for example, a CPU, an MCU, etc.

[0066] The processor (300) determines a catalyst (130) to mediate a reaction in the catalytic reactor (100). For example, the processor (300) calculates a predetermined temperature required for the catalyst (130) to mediate the reaction. The processor (300) allows the catalytic reactor (100) to be heated to a predetermined temperature. The predetermined temperature includes, for example, a temperature range. The temperature range includes, for example, a section from 1) a temperature at which the catalyst (130) begins to mediate the reaction to 2) a temperature at which the catalyst (130) ends mediating the reaction. Alternatively, the temperature range includes, for example, a section from 1) a temperature at which the catalyst (130) begins to mediate the reaction to 2) a temperature before the catalyst (130) and / or a material (reactant) whose reaction is promoted by the catalyst (130) is damaged. The processor (300) controls the electric heater (110) so that the catalytic reactor (100) is heated to a predetermined temperature.

[0067] Meanwhile, the sensor (200) senses temperature. The sensor (200) measures, for example, the temperature inside the catalytic reactor (100). The processor (300) can determine whether the catalytic reactor (100) has reached a predetermined temperature based on the temperature measured by the sensor (200). The processor (300) determines whether the catalytic reactor (100) has reached a predetermined temperature based on the measured internal temperature, and determines the intensity of the current output from the electric heater (110). This will be described in more detail with reference to FIG. 3 below.

[0068] Through this configuration, the catalytic reaction system (1000) according to the embodiments provides a method for efficiently using electrical energy to cause a catalyst to react.

[0069]

[0070] Figure 3 is a schematic diagram illustrating a catalytic reactor control method according to embodiments.

[0071] FIG. 3 describes the catalytic reactor (100) described in FIGS. 1 and 2 and a method for controlling the catalytic reactor (100).

[0072] A method for controlling a catalyst reactor according to embodiments includes a step (s101) of calculating a predetermined temperature of a catalyst. The processor (300) calculates the predetermined temperature of the catalyst (130) housed inside the catalyst reactor (100). For example, the processor (300) calculates and / or retrieves the predetermined temperature from data previously stored in a memory (not shown). Or, for example, the processor (300) receives a value for the predetermined temperature through a communication unit (not shown). Or, for example, the processor (300) searches for a value for the predetermined temperature through a crawling unit (not shown). Or, for example, the processor (300) receives a value for the predetermined temperature from a user through an input unit (not shown). Hereinafter, all actions such as calculation, retrieval, reception, search, and input may be collectively referred to as "calculation."

[0073] A method for controlling a catalytic reactor according to embodiments includes a step (s102) of applying current based on a predetermined temperature. The processor (300) calculates the intensity of current required for the reactor (120) to reach the predetermined temperature. The processor (300) controls the electric heater (110) according to the calculated intensity of current. For example, the processor (300) causes the electric heater (110) to apply current to the reactor (120) in an amount equal to the calculated intensity of current.

[0074] A method for controlling a catalytic reactor according to embodiments includes a step (s103) of measuring the temperature of the reactor. The sensor (200) measures the temperature of the reactor (120). For example, the sensor (200) measures the temperature of the reactor (120) through a contact method in which the sensor (200) contacts the inner and / or outer walls of the reactor (120). For example, the sensor (200) includes a thermocouple that measures temperature through electromotive force, an RTD that measures temperature through resistance, a thermistor, etc. Alternatively, the sensor (200) includes a liquid thermometer whose state changes depending on temperature, a bimetal temperature sensor, etc. Alternatively, for example, the sensor (200) measures the temperature of the reactor (120) through a non-contact method in which a wavelength emitted from the reactor (120) is acquired. For example, the sensor (200) includes an infrared temperature sensor that measures temperature by detecting a wavelength such as infrared. However, the method in which the sensor (200) measures the temperature of the reactor (120) is not limited thereto.

[0075] The method for controlling a catalytic reactor according to the embodiments includes a step (s104) of determining whether the measured temperature is below a predetermined temperature. The processor (300) compares the temperature of the reactor (120) measured by the sensor (200) with the magnitude of the predetermined temperature calculated in s101.

[0076] The method for controlling a catalytic reactor according to embodiments includes a step (s105) of increasing the intensity of a current when it is determined that the measured temperature is lower than a predetermined temperature. When the measured temperature is lower than the predetermined temperature, the processor (300) determines that the intensity of the current calculated in s102 is insufficient to reach the predetermined temperature. The processor (300) increases the intensity of the current so that the reactor (120) can reach the predetermined temperature. The electric heater (110) applies a current having the increased intensity to the outer wall of the reactor (120). At this time, the size of the increased portion of the increased intensity of the current is a preset size, and includes, for example, at least one of 5 mA, 10 mA, 15 mA, 20 mA, 25 mA, 30 mA, 5 A, 10 A, 15 A, 20 A, and 25 A. At this time, the size of the increased portion is a value that does not exceed 50% of the intensity of the current initially applied in s102. Through this, the embodiments present a method for appropriately compensating the intensity of the current when the intensity of the applied current is low.

[0077] The method for controlling a catalytic reactor according to the embodiments includes a step (s106) of determining whether the measured temperature exceeds the predetermined temperature if it is determined that the measured temperature is not below the predetermined temperature. The processor (300) compares the temperature of the reactor (120) measured through the sensor (200) with the magnitude of the predetermined temperature calculated in s101.

[0078] The method for controlling a catalytic reactor according to embodiments includes a step (s107) of reducing the current intensity when it is determined that the measured temperature exceeds a predetermined temperature. When the measured temperature exceeds the predetermined temperature, the processor (300) determines that the current intensity calculated in s102 is excessive for reaching the predetermined temperature. The processor (300) reduces the current intensity so that the reactor (120) can reach the predetermined temperature. The electric heater (110) applies a current having a reduced current intensity to the outer wall of the reactor (120). At this time, the reduced portion of the reduced current intensity is a preset predetermined amount, and includes, for example, at least one of 5 mA, 10 mA, 15 mA, 20 mA, 25 mA, 30 mA, 5 A, 10 A, 15 A, 20 A, and 25 A. At this time, the magnitude of the reduced portion is a value that does not exceed 50% of the intensity of the current initially applied in s102. Through this, the embodiments present a method for appropriately compensating the intensity of the current when the intensity of the applied current is high.

[0079] Meanwhile, if the processor (300) determines that the measured temperature is neither lower than nor higher than the predetermined temperature, it continues to apply the current intensity calculated in s102 to the outer wall of the reactor (120).

[0080] Through such methods, the embodiments can efficiently utilize electrical energy while providing a heat source of the optimal size for catalytic reaction mediation. Furthermore, the embodiments can prevent environmental damage during this process.

[0081] Through FIGS. 1 to 3, a catalytic reactor, a catalytic reaction system including such a catalytic reactor, and a catalytic reactor control method have been described. Below, FIGS. 4 to 11 describe various examples of a catalytic reactor (100). It goes without saying that the catalytic reactor (100) described in FIGS. 4 to 11 is applicable to the catalytic reaction system and / or catalytic reactor control method described in FIGS. 2 to 3.

[0082]

[0083] Figure 4 is a schematic diagram showing a catalytic reactor according to embodiments.

[0084] The catalytic reactor (100) according to the embodiments includes an electric heater (110), a reactor (120), a catalyst (130), and a support (150). The description of the electric heater (110), the reactor (120), and the catalyst (130) is the same as or similar to that in FIGS. 1 to 3.

[0085] The support (150) is a structure formed inside the reactor (120). The support (150) may be formed in a straight shape, for example, as illustrated in FIG. 4, but is not limited thereto. The support (150) may include a curved surface or may be formed in a spiral shape, for example. In addition, the support (150) may be formed in a pellet shape.

[0086] The support (150) is formed not parallel to the outer wall of the reactor (120). Therefore, one side of the support (150) is in contact with one side of the outer wall of the reactor (120), and the other side of the support (150) is in contact with the other side of the outer wall of the reactor (120). The support (150) may be formed at a 90 degree angle with respect to the outer wall of the reactor (120), for example, as illustrated in FIG. 4, but the support (150) may be formed at any angle other than 180 degrees with respect to the outer wall of the reactor (120).

[0087] The catalytic reactor (100) may include one or more supports (150). When the catalytic reactor (100) includes a plurality of supports (150), each of the plurality of supports (150) may be arranged to be spaced apart from each other by the same distance. However, each of the plurality of supports (150) may be arranged to be spaced apart from each other by different distances, and further, at least some of the plurality of supports (150) may be entangled or in contact with each other.

[0088] The support (150) may comprise, for example, the same material as the outer wall of the reactor (120). For example, the support (150) may comprise a conductive material, for example, a metal. Alternatively, the support (150) may comprise a ferromagnetic material having a Curie temperature higher than the operating temperature. Here, the Curie temperature is the temperature at which a magnetic material loses its ferromagnetic properties and is replaced by paramagnetism.

[0089] The support (150) can be energized by a current applied to the outer wall of the reactor (120). In this case, the support (150) can generate heat due to resistance heat. Accordingly, the support (150) can enable the catalytic reactor (100) to more efficiently supply heat to its interior. In addition, the catalytic reactor (100) according to the embodiments can allow the core of the catalyst (130) to be heated through the support (150).

[0090]

[0091] Figure 5 is a schematic diagram showing a catalytic reactor according to embodiments.

[0092] The catalytic reactor (100) according to the embodiments includes an electric heater (110), a reactor (120), a catalyst (130), and a load (160). The description of the electric heater (110), the reactor (120), and the catalyst (130) is the same as or similar to that in FIGS. 1 to 4.

[0093] A rod (160) is provided inside the reactor (120). The rod (160) can transfer heat to the deep part of the catalyst (130) while passing through the catalyst (130).

[0094] For this purpose, for example, the rod (160) may be in the form of a long rod inserted into the center of the reactor (120). At this time, the cross-section of the rod (160) may be any shape, including a circle, a polygon, and an ellipse. Alternatively, for example, the rod (160) may be in the form of a shield that equally divides the internal spaces of the reactor (120). In this case, the fluids (141, 142) flowing inside the reactor (120) may flow to one side (F) in each of the divided spaces.

[0095] Unlike the support (150), the rod (160) is formed parallel to the outer wall of the reactor (120). For example, the rod (160) may be formed long in the flow direction (F) of the fluid (140).

[0096] At this time, the length of the rod (160) may be the same as the outer wall of the reactor (120). However, the rod (160) may be formed shorter than the reactor (120), thereby contributing to reducing the manufacturing cost of the catalytic reactor (100). Alternatively, the rod (160) may be formed longer than the outer wall of the reactor (120), thereby enabling easier connection to the electric heater (110), as described below.

[0097] For example, the rod (160) may have pores formed on the surface and / or may include unevenness to increase the specific surface area.

[0098] The rod (160) includes a conductive material. The rod (160) may include, for example, the same material as the outer wall of the reactor (120). For example, the rod (160) includes a metal, a carbon rod, or the like. Alternatively, the rod (160) includes a ferromagnetic material.

[0099] The electric heater (110) can be connected to the outer wall of the reactor (120) as well as the load (160). The electric heater (110) can apply current to the load (160). The load (160) can generate resistive heat by the current flowing through the load (160).

[0100] Through this configuration, the catalytic reactor (100) according to the embodiments allows heat to be supplied more efficiently to the interior of the catalytic reactor (100) through the rod (160). In addition, the embodiments can allow the core of the catalyst (130) to be heated through the rod (160).

[0101] Figure 6 is a schematic diagram showing a catalytic reactor according to embodiments.

[0102] The catalytic reactor (100) according to the embodiments includes an electric heater (110), a reactor (120), a catalyst (130), and a coil (170). The description of the electric heater (110), the reactor (120), and the catalyst (130) is the same as or similar to that in FIGS. 1 to 5.

[0103] The coil (170) is formed by winding the outer wall of the reactor (120). The coil (170) includes a conductive material.

[0104] An electric heater (110) can be connected to a coil (170). The electric heater (110) applies current to the coil (170). The coil (170) generates a magnetic field according to the applied current. The coil (170) can supply heat to the catalytic reactor (100) through inductive heating by the magnetic field.

[0105] Meanwhile, the catalytic reactor (100) may further include a cooling unit (not shown).

[0106] For example, the coil (170) may generate internal electrical resistance due to the current flowing through the coil (170). In this case, the coil (170) may generate heat due to the electrical resistance, thereby increasing its temperature. If the temperature of the coil (170) increases, the efficiency of forming a magnetic field may decrease. The cooling unit can solve this problem by controlling the temperature of the coil (170).

[0107] For example, a cooling unit is provided outside or inside the reactor (120). For example, the cooling unit includes a refrigerant and a pipe through which the refrigerant flows. The cooling unit allows the temperature of the coil (170) to be lowered from the outside of the coil (170) through the refrigerant.

[0108] Specifically, the pipe may be formed by wrapping around the outer surface of the reactor (120).
