Abstract
Description
Technical Field
[0001] The present invention relates to the field of chemical engineering technology, and particularly relates to a self-rotating super / micro-gravity - micro-interface synergistic enhanced catalytic hydrogenation device for petroleum resin and a method for using the same. Background Art
[0002] Petroleum resin is a thermoplastic resin obtained by polymerizing C5 - C9 fractions by-products in the process of ethylene production from naphtha cracking. However, petroleum resin contains a large number of unsaturated double bonds, which are prone to oxidation or substitution reactions, resulting in poor photothermal stability and darker color, severely limiting its application range. By hydrogenating and modifying petroleum resin, high-quality hydrogenated petroleum resin can be obtained, and its chromaticity, stability, and miscibility can be greatly improved, and it is widely used in fine chemical fields such as food packaging, pressure-sensitive adhesives, and sanitary products. As a macromolecular polymer with a relative molecular mass of 300 - 3000, petroleum resin has the characteristics of large molecular diameter and high solution viscosity, and there is an obvious resistance to its diffusion in the solution, resulting in difficulty for petroleum resin molecules to approach the active components in the catalyst. Therefore, it is difficult to efficiently hydrogenate petroleum resin. Currently, some invention patents have been applied for the technology of catalytic hydrogenation of petroleum resin as follows.
[0003] CN106832127B discloses an industrial manufacturing method of hydrogenated petroleum resin. This method adopts a two-stage hydrogenation and combined alkali washing and neutralization process. Under the condition of the presence of a suitable hydrogenation catalyst and solvent, the petroleum resin obtained by polymerizing cracked C5 and C9 fractions undergoes a hydrogenation reaction. The unsaturated components in the petroleum resin are hydrogenated to reduce the double bond content, the colored groups are hydrogenated to decolorize, and the residual chlorine in the polymerization process is removed by hydrogenation. After alkali washing, water washing, injection of stabilizer, and solvent removal, a light-colored or colorless hydrogenated petroleum resin is obtained.
[0004] CN106832127B discloses a method for preparing hydrogenated C9 petroleum resin by directional hydrogenation, including: (1) mixing C9 petroleum resin with a mixed solvent evenly and then removing impurities through an Al2O3 packing bed; (2) feeding the pretreated resin liquid into a first-stage hydrogenation reactor loaded with Ni / Mo / W Al2O3 catalyst for hydrogenation reaction to obtain a first-stage hydrogenated resin liquid; (3) feeding the above first-stage hydrogenated resin liquid into a pressure stabilizing flash distillation tower, and obtaining a desulfurized resin liquid at the bottom of the tower; (4) mixing the desulfurized resin liquid with hydrocracking jet fuel evenly and then feeding it into a second-stage hydrogenation reactor for hydrogenation reaction to obtain a second-stage hydrogenated resin liquid; (5) feeding the second-stage hydrogenated resin liquid into a vacuum distillation tower, and obtaining hydrogenated C9 petroleum resin at the bottom of the tower.
[0005] CN105772042B provides a C5 petroleum resin hydrogenation catalyst and its preparation method. The C5 petroleum resin hydrogenation catalyst consists of a carrier and an active component supported on the carrier. The carrier is silica, and the active component is nickel phosphide and ruthenium phosphide. Based on the mass of the silica carrier, the loading amount of nickel phosphide is 10 wt% - 20 wt% calculated as nickel, and the loading amount of ruthenium phosphide is 0.5 wt% - 1 wt% calculated as ruthenium.
[0006] CN104877077B discloses a method for preparing hydrogenated C9 petroleum resin, belonging to the technical field of resin hydrogenation. Using a Ni / ZnO catalyst as a hydrogenation adsorption desulfurization catalyst and a supported metal catalyst as a hydrogenation decolorization catalyst, the resin is subjected to a hydrogenation reaction in a two-stage fixed-bed continuous hydrogenation mode. Due to the use of the Ni / ZnO hydrogenation adsorption desulfurization catalyst, the service life of the supported metal catalyst is ensured.

[0048] Example 2
[0049] Reference Figures 1 to 3 , such as the usage method of the self-rotating ultra / micro-gravity - micro-interface synergistic enhanced catalytic hydrogenation device for petroleum resin in Example 1, the operation steps are as follows:
[0050] 1) The first heat exchange fluid inlet 9 and the first heat exchange fluid outlet 4 of the cylindrical heat exchanger 7 are connected to the device providing the cold fluid. The diameter of the cylindrical heat exchanger 7 is 240 mm, the length of the cylindrical heat exchanger 7 is 1800 mm, and there are 8 baffles 11 in the cylindrical heat exchanger 7.

[0074] In the formula: G - centrifugal acceleration, m / s 2 ; R - radius of circular motion, that is, the radius of each turn of the coil 10, m; g - acceleration of gravity of the earth, m / s 2 ; ω - angular velocity of circular motion, that is, the angular velocity of the material moving in the coil 10, 1 / s; β - ultra / micro gravity factor; N - rotational speed of circular motion, r / min; π - pi; V - linear velocity of circular motion, that is, the flow rate of the material in the coil 10, m / s.
[0075] Among them, β and r are known values. β takes specific numerical values to make the material in a microgravity or hypergravity state in the fluid reactor. When the centrifugal acceleration G is 1 to 50 times the acceleration of gravity g of the earth, that is, when β = 1 to 50, it is a microgravity field effect. When the centrifugal acceleration G is greater than 50 times the acceleration of gravity g of the earth, that is, when β > 50, it is a hypergravity field effect. The value of β is selected according to the viscosity, density, temperature and chemical reaction characteristics of the material. The material in the hyper / microgravity field makes the heterogeneous reaction materials form millimeter-sized or micron-sized small droplets and small bubbles, efficiently promoting the mixing between the phases of the heterogeneous reaction materials and strengthening the transfer process.
[0076] Specifically, the petroleum resin solution and hydrogen enter the coil 10 and are in a hypergravity state, with β = 70. At this time, G = 686.7 m / s 2 , V = 17.63 m / s, which is the velocity of the petroleum resin solution and hydrogen entering the coil 102.
[0077] 2) The petroleum resin solution flowing in from the first petroleum resin solution inlet 12 and each second petroleum resin solution inlet 5, and the hydrogen flowing in from the hydrogen inlet 6 rotate circumferentially in the coil 102 to generate centrifugal force. Under the action of the centrifugal force generated by the high-speed self-rotating flow, it can overcome gravity to form a hyper / microgravity-micro interface field, achieving the strengthening of the transfer process of the reaction system. And during this process, the petroleum resin solution and hydrogen are fully mixed and reacted. After the reaction is completed, the obtained reactants are discharged from the material outlet 8. During the reaction, the cold fluid enters from the first heat exchange fluid inlet 9, exchanges heat with the reaction material in the coil 10, and then flows out through the first heat exchange fluid outlet 4 to cool the reaction material in the coil 10.

[0079] Reference Figures 1 to 3 , such as the usage method of the self-rotating hyper / microgravity-micro interface synergistic strengthening petroleum resin catalytic hydrogenation device in Example 1, the operation steps are as follows:
[0080] 1) The first heat exchange fluid inlet 9 and the first heat exchange fluid outlet 4 of the cylindrical heat exchanger 7 are connected to the device that provides the cold fluid. The diameter of the cylindrical heat exchanger 7 is 1250 mm, and the length of the cylindrical heat exchanger 7 is 5000 mm. There are 9 baffles 11 inside the cylindrical heat exchanger 7, and the distance between adjacent two baffles 11 is 500 mm, which is used to cool the reaction material in the cooling coil 10. The pipe diameter of the coil 10 is 100 mm, the number of turns of the coil 10 is 30 turns, and the diameter of each turn of the coil 10 is 1200 mm. Moreover, the second heat exchange fluid inlet 13 and the second heat exchange fluid outlet 2 of the preheater 3 are connected to the device that provides the hot fluid for heat exchange to preheat the petroleum resin solution flowing through the preheater 3, thereby improving the fluidity of the petroleum resin solution. The petroleum resin solution is transported to the preheater 3 for preheating by the first fluid conveyor 1 and then transported into the coil 10; and hydrogen is transported into the coil 10 by the second fluid conveyor so that the petroleum resin solution and hydrogen can be mixed and reacted in the coil 10. The flow rate V of the petroleum resin solution transported by the first fluid conveyor 1 and the flow rate V of the hydrogen transported by the second fluid conveyor are determined by the value of β. Through the action of the first fluid conveyor 1 and the second fluid conveyor, the flow rate V of each petroleum resin solution and the flow rate V of hydrogen are controlled to be 26.6 m / s. The specific calculation formula is as follows:

The material in the hyper / microgravity field makes the heterogeneous reaction materials form millimeter-sized or micron-sized small droplets and small bubbles, efficiently promoting the mixing between the heterogeneous reaction material phases and strengthening the transfer process.
[0086] Specifically, the petroleum resin solution and hydrogen enter the coil 10 and are in a hypergravity state, and β = 120. At this time, G = 1177.2 m / s 2 , V = 26.6 m / s, which is the speed of the petroleum resin solution and hydrogen entering the coil 102.
