The invention discloses a supported
nickel-based catalyst, a preparation method thereof, and an application of the catalyst in
catalytic hydrogenation of C5 / C9
petroleum resin. The catalyst is a mesoporous hollow nanosphere catalyst Ni-M-SiO2 prepared by taking SiO2 as a carrier, taking Ni as a main active
metal center, and adding an assistant
metal M (M=Cu / Co / Mg). The prepared catalyst has a relatively large specific surface area, the particle size of active
metal particles is small, dispersion is uniform, the
binding force with the carrier is strong, and loss and agglomeration do not occur easily in a reaction process. When being applied to a
hydrogenation reaction of C5 / C9
petroleum resin, the catalyst not only has relatively high
catalytic hydrogenation activity and decoloring performance, but also can effectively inhibit great reduction of the
softening point, and is suitable for preparing high-quality hydrogenated
petroleum resin. The obtained product is low in
bromine price (smaller than 1.2 g Br2 / 100 g), small in
color scale (
Gardner color scale smaller than 0.6), and is high in
softening point (larger than 84 DEG C).
