[0002] Currently, the catalysts used in industry are mainly supported palladium catalysts and supported nickel-tungsten sulfide catalysts. There are also reports of the application of nickel-based catalysts. Hydrogenation catalysts are chemical substances used to promote the hydrogenation reaction of C5 petroleum resins. They enhance the performance of C5 petroleum resins by accelerating the reaction rate, reducing the energy required for the reaction, or changing the reaction pathway. Hydrogenation catalysts for C5 petroleum resin production play a crucial role in the production of petroleum resins. Through specific preparation methods and compositions, they effectively promote the hydrogenation reaction of C5 petroleum resins, improving the performance and applicability of the products.

[0003] The existing hydrogenation catalyst preparation equipment for C5 petroleum resin production has uneven stirring, which leads to uneven distribution of components in the resin, thus affecting the stratification effect and the uneven distribution of active components in the catalyst particles, thereby affecting the hydrogenation activity of the catalyst.

[0014] (III) Beneficial Effects

[0015] This invention provides an apparatus for preparing a hydrogenation catalyst for the production of C5 petroleum resin. It has the following beneficial effects:

[0016] (1) The hydrogenation catalyst preparation device for C5 petroleum resin production can ensure that the active components are evenly distributed on the catalyst support by stirring evenly, avoiding local concentrations that are too high or too low. Even stirring is conducive to full contact between the catalyst and the reactants, improving the efficiency and uniformity of the hydrogenation reaction. Evenly stirred catalysts are less prone to problems such as clumping and breakage during use, thus extending their service life. Evenly stirred catalysts can improve the rate and conversion rate of the hydrogenation reaction, thereby shortening the production cycle and improving production efficiency. Evenly stirred catalysts have higher stability and can resist poisoning by impurities such as sulfur and chlorine. Evenly stirred catalysts can ensure that the reaction products have better uniformity in terms of color, stability, and heat resistance, meeting various application requirements.

[0017] (2) The hydrogenation catalyst preparation device for C5 petroleum resin production uses bubble injection to make the fusion of resin and hydrogen catalyst in the preparation equipment after hydrogenation catalyst more thorough. Moreover, it avoids the use of direct stirring device and can be fully automated, avoiding the gas generated by the reaction of resin and hydrogenation catalyst during stirring from harming the staff.
