Abstract

The invention discloses a C5 petroleum resin hydrogenation catalyst and a preparation method thereof. The C5 petroleum resin hydrogenation catalyst comprises the following components: (a) a carrier which is a mixture of an ordered mesoporous silicate molecular sieve and Ta2O5; (b) an active metal which is Ni; and (c) an auxiliary agent which is one or more of group IV A elements. The C5 petroleum resin hydrogenation catalyst prepared by the preparation method is beneficial to diffusion of C5 petroleum resin molecules as a reaction raw material and is not easy to coke on the catalyst, the hydrogenation activity of the catalyst can be remarkably improved by modification of the auxiliary agent, and the C5 petroleum resin hydrogenation catalyst has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of catalysts, and in particular relates to a C5 petroleum resin hydrogenation catalyst and a preparation method thereof. Background technique [0002] C5 petroleum resin is thermoplastic, with an average molecular weight between 300 and 3000. The main chain link of this type of resin is aliphatic structure, which has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical corrosion resistance. Hydrogenated carbon five resin is a colorless, odorless, high light and oxygen stable resin obtained by hydrogenation of carbon five resin. It is a common yellow resin in specific fields, especially furniture adhesives, inks, high-grade paper, coatings, etc. The upgrade of additives used in the field. With the improvement of human health and environmental protection requirements, hydrogenated C5 resin will gradually replace the production capacity of C5 petroleum resi...
