Abstract

The invention provides a hydrogenation catalyst for petroleum resin, a preparation method and an application thereof. The catalyst comprises alumina, titanium oxide, cerium oxide and nickel, wherein the alumina, titanium oxide and cerium oxide are used as an alumina-titanium oxide-cerium oxide composite carrier, and the metal nickel is loaded on the composite carrier. The preparation method comprises the following steps: 1, preparing an alumina-titanium oxide-cerium oxide composite carrier; and 2, dipping the alumina-titanium oxide-cerium oxide composite carrier in a nickel salt solution, carrying out microwave heating, and roasting to obtain the catalyst. The hydrogenation catalyst provided by the invention is used for catalytic hydrogenation of petroleum resin, and has high hydrogenationactivity and high hydrogenation rate, and the produced hydrogenated resin can reach stable main quality indexes such as No. 01 color, chromaticity and softening point, and meets the requirements of high-grade petroleum resin.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to a hydrogenation catalyst for petroleum resins and its preparation method and application. Background technique [0002] Petroleum resin is made from the C5 and C9 fractions of ethylene cracking as raw materials, and is formed by cationic polymerization of dienes and monoenes in the C5 and C9 components. After further hydrogenation modification, water-white hydrogenated petroleum resin can be obtained. Hydrogenated petroleum resin has good tackiness, compatibility, thermal stability and light stability, and can improve the adhesive performance of adhesiveness. It is an essential tackifying component of many adhesives. Widely used in hot melt, pressure sensitive adhesive, structure and decoration of construction industry, automobile assembly, tires, commodity packaging, book binding, sanitary products, shoemaking, hot-melt road marking paint, colored asphalt and other...
