Problems solved by technology

[0003] Catalyst During the precipitation process, the acidic nickel salt solution is added to the alkaline precipitant solution, causing the environment of the precipitation process in the reactor to be uneven, resulting in different sizes of precipitated grains, which affect the activity level of nickel. , reduce the activity of the catalyst, and add the alumina carrier after the precipitation is completed. This process belongs to the mixing of two solid substances, which is not conducive to the dispersion of nickel, reduces the utilization rate of active metals, and the catalyst activity is low

Abstract

The invention provides a catalyst for hydrogenation reaction of C9 petroleum resin and a preparation method thereof, and relates to the technical field of catalysis. The catalyst comprises a carrier and active components, wherein the catalyst comprises the carrier comprising 30-50 parts of silicon carbide, 30-50 parts of TiO2 and 20-40 parts of SiO2; 0.2-0.8 part of a pore-enlarging agent; 1-5 parts of the active component and 10-15 parts of graphite; the preparation method comprises the following steps: A, carrying out heat treatment on the silicon carbide and TiO2; B, mixing the mixture withat least one of gamma alumina, aluminum stearate and aluminum nitrate; C, adding the pore-enlarging agent into the mixture; D, obtaining the catalyst carrier; and F, taking out the impregnated catalyst carrier. The addition of the pore-enlarging agent is beneficial to the formation of secondary pores in the roasting process, provides a larger pore size for the composite carrier, and can provide amore favorable hydrogenation environment; the application of the active component improves the sintering resistance of noble metal element microcrystals under the condition of high-temperature hydrogenation reaction; the whole process is simple; and the obtained catalyst has longer service life, better catalytic effect and high practicability.

Description

technical field [0001] The invention relates to the technical field of catalysis, in particular to a catalyst for hydrogenation reaction of C9 petroleum resin and a preparation method thereof. Background technique [0002] C9 petroleum resins are widely used in adhesive tapes, hot melt adhesives, road materials, inks and rubbers. The C9 petroleum resin without hydrogenation reduction has a single variety, and the product quality is not high, especially the internal quality indicators such as oil solubility, compatibility and oxidation stability are unstable. Catalytic hydrogenation reduction treatment of C9 petroleum resin can better solve the above problems, improve the product performance, broaden the application range of the product and increase the added value of the product. At present, the hydrogenation reduction of petroleum resin is mainly based on C5, and foreign research on catalytic hydrogenation reduction of petroleum resin has entered the stage of industrial ap...
