Abstract

The invention relates to a high-fluorine-containing C9 resin hydrogenation catalyst, which is composed of an active component M1, an auxiliary agent component M2 and a carrier component M3. Based on 100% of the total weight of the catalyst, the content of the M1 component is 37%-54%, the content of the M2 component is 4%-6%, and the balance is the M3 component. The component M1 contains Ni, Mo, Cu and Al, the component M2 contains Sm and Na, and the component M3 is amorphous silicon-aluminum MgAl2O4 composite oxide. The invention also discloses a preparation method and application of the catalyst. The catalyst provided by the invention is used for hydrogenation removal of fluorine and sulfur in C9 resin, and can effectively delay fluorine and sulfur poisoning of a rear-stage hydrogenation catalyst.

Description

Technical field[0001]The present invention relates to a high fluorine C9 resin hydrogenation catalyst, and further involves the preparation method of the catalyst, and its application in hydrogenation of hydrogen-containing C9 resin.Background technique[0002]The C9 resin is a thermoplastic resin obtained by the C9 fraction of the by-product in industrial ethiically e.flusion, which is heated or catalyzed by a thermoplastic resin obtained by the polymerization. Since its tackiness is strong, it is better to compatibility with other oils and resins. , Widely used in binder, road lacquer, ink and rubber and other industries. The C9 fraction typically contains impurities such as sulfur, nitrogen, olefins, and BF is used in C9 resin catalytic polymerization3The catalyst such that the C9 resin contains higher fluorine, and the above impurities cause a high resin chromaticity and poor photothermal stability, so that the application is limited. At present, Hydrogenation modification of C9 r...
