Abstract

The disclosed hydrogenation and discolor method relates mainly to catalyze the C5 and C9 petroleum resin with modified frame nickel on mild condition. This invention reduces unsaturated bond in product obviously, and improves the resin hue to water white.

Description

technical field [0001] The invention belongs to framework nickel catalyst C 5 and C 9 Petroleum resin hydrogenation application technology field, is a kind of C 5 and C 9 Petroleum resin kettle-type catalytic hydrogenation decolorization and deodorization method Background technique [0002] Petroleum resin is a by-product of ethylene plant C 5 、C 9 Distillate is the main raw material, and it is polymerized in the presence of a catalyst, or it is a thermoplastic resin obtained by copolymerizing it with aldehydes, aromatic hydrocarbons, and terpenes. Its molecular weight is generally less than 2000, and its softening point is 5-150°C. It is a thermoplastic viscous liquid or solid. According to different raw material sources and polymerization methods, it is generally divided into: C-5 (aliphatic hydrocarbon resin), C-5 / C-9 (aliphatic hydrocarbon, aromatic hydrocarbon resin), C-9 (aromatic hydrocarbon resin) and dicyclopentadiene vinyl resin (DCPD). Petroleum resin has...
