Description

[Technical Field]

[0001] The present invention relates to a process for preparing syngas (also known as synthesis gas) by a partial oxidation reaction of one or more organic compounds, wherein at least a portion of the one or more organic compounds are provided in liquid form, and the partial oxidation is preferably carried out without the use of a catalyst. [Background technology]

[0002] Generally, syngas contains H2 and CO, and can also contain CO2 and / or H2O. Syngas with specific H2-CO molar ratios can be prepared as needed. The preparation of syngas is typically carried out by partial oxidation of organic compounds in the presence of one or more of O2 and / or vapor. CO2 is produced as a byproduct and can be separated from the product stream. The separated CO2 can also be recycled back into the preparation process.

[0003] International Publication No. 2015 / 090575 relates in general to methods and apparatus for producing syngas.

[0004] International Publication No. 2022 / 200532 relates to a method for producing a synthesis gas mixture containing hydrogen and carbon monoxide by non-catalytic partial oxidation of hydrocarbons in the presence of oxygen and carbon dioxide. In this method, a reaction gas containing at least hydrocarbons, a reaction gas containing oxygen, and a reaction gas containing carbon dioxide are supplied to a partial oxidation reactor and react at a temperature in the range of 1200 to 1550°C to obtain a product gas mixture containing hydrogen, carbon monoxide, and carbon dioxide, and at least a portion of the carbon dioxide is separated from the product gas mixture and supplied back to the partial oxidation reactor. This method is characterized in that the carbon dioxide supplied to the partial oxidation reactor includes additional externally introduced carbon dioxide, and a product gas mixture with a hydrogen-to-carbon monoxide molar ratio in the range of 0.8:1 to 1.6:1 is obtained in the partial oxidation reactor.

[0005] U.S. Patent No. 10435295 relates to a method for preparing liquid fuel from syngas, the method specifically comprising the steps of: preparing a waste conversion reactor having a decomposition chamber; thermally decomposing waste, including organic and inorganic waste, in the waste conversion reactor to produce high-temperature syngas from the organic material and slag from the decomposition of the inorganic waste; the waste conversion reactor comprising a submerged arc furnace or plasma torch furnace that supplies heat to the decomposition chamber for the thermal decomposition and decomposition of the organic and inorganic waste materials; and introducing the syngas into a liquid fuel synthesis system comprising one or more synthetic fuel conversion reactors, where the syngas is converted into liquid fuel. Claim 7 discloses that one or more exhaust streams from the synthetic fuel conversion reactor, including water, carbon dioxide, and tail gas, may be introduced into the waste conversion reactor.

[0006] U.S. Patent Application Publication No. 2016 / 0362355 relates to the preparation of a gasoline oil product. This product contains hydrocarbon compounds in a range corresponding to the composition of gasoline. The refining process of the dimethyl ether (DME) used reduces the supply rate and allows for smaller reactors while keeping costs down. Carbon dioxide (CO2) is separated and recycled to a gasifier, where it can be reused, stored, or used for other purposes to improve the global environment. Simultaneously, CO2 can be reacted with hydrocarbons, water vapor, etc., via a high-temperature plasma torch to produce synthesis gas (syngas) of carbon monoxide (CO) and hydrogen (H2), adjusting the hydrogen / carbon ratio of the compound synthesized with biomass or hydrocarbons and assisting subsequent chemical synthesis reactions. The final gasoline produced is of high yield and high octane rating, with low nitrogen and sulfur pollution, and possesses very "environmentally friendly" quality.

[0007] International Publication No. 2021 / 180482 discloses a process for producing synthesis gas by gasification of carbon-containing materials, preferably by plasma gasification, using a gasification gas comprising at least 2 mol% carbon dioxide and optionally at least one gas selected from steam, oxygen, hydrogen, methane, and air, in which external energy obtained from electricity is supplied to the gasification step, and the exhaust gas of this process, which contains carbon dioxide, is at least partially recycled back into the gasification step. Furthermore, the invention proposes a process for producing a synthesis gas downstream product, by which synthesis gas is produced and used as an intermediate product in a downstream synthesis process.

[0008] U.S. Patent Application Publication 2022 / 234889(A1) relates to a method for controlling syngas composition by reactor temperature. In particular, a method for producing syngas is disclosed, which involves the partial oxidation of a hydrocarbon feedstock, in which the partial oxidation is carried out under specific reaction conditions.

[0009] European Patent Application Publication No. 3878807(A1) relates to a synthesis gas production process by external heat gasification using controlled carbon dioxide reduction. In particular, a synthesis gas production process by gasification of carbon-containing materials is disclosed.

[0010] Since organic compounds exist in liquid form, a process was required to prepare syngas using one or more organic compounds in liquid form. [Prior art documents] [Patent Documents]

[0165] The unit bara is an absolute pressure of 10⁻⁶ 5 This refers to Pa.

[0166] The present invention is further illustrated by the following embodiments.

[0167] Examples Reference Example 1: Measurement of liquid phase viscosity Viscosity was measured at 20°C using a Brookfield RV type laboratory viscometer with a spindle #4 or #5 at 100 revolutions per minute, in accordance with the standard method DIN EN ISO 3219:1994.

[0168] Comparative Example 0 and Examples 1-5: Process for preparing syngas The process for preparing the syngas was simulated using Aspen (Aspen version V14). To prepare the first feed stream according to the present invention, a feed stream containing an organic compound was mixed with a CO2-containing feed stream.

[0169] The conditions described in Tables 1-3 below were set. The pressures of the high-pressure-reduced residue flow, CO2 flow, steam flow for the first feed flow, O2 flow, steam flow for the second feed flow, the first feed flow, and the second feed flow were set independently to 47 bara.

[0170] The prepared flows were mixed and reacted by gasification.

[0171] [Table 1]

[0172] [Table 2]

[0173] [Table 3]

[0174] [Table 4]

[0175] In Examples 15 and 16, the weight ratios of organic matter to CO2 in the first feed stream were 47 and 0.22, respectively.

[0176] In Comparative Example 17, the weight ratio of organic matter to CO2 in the first feed stream was 0.18. Due to the CO2, a flame could not develop, and the gasification reaction did not occur. Therefore, the required temperature in the reactor was not reached, and the simulation could not be performed. Consequently, no results were obtained for Comparative Example 17.

[0177] As can be inferred from the results, a process for preparing syngas can be provided that reduces the amount of steam. Furthermore, the process according to the present invention allows for the recirculation of CO2. In particular, the recirculated CO2 can be used to spray the liquid feed stream. Thus, syngas with a relatively high CO content can be prepared according to the present invention. In addition, it has been found that by recirculating CO2, mass flow rate leveling is achieved, and as a result, a steady-state process can be realized.
