Embodiment

[0013] The hydrogenation catalyst is firstly prepared by spraying method. The weight of the catalyst carrier alumina is 100 parts, 0.8 part of palladium, 0.2 part of transition metal copper, 0.5 part of rare earth metal cerium, and 1 part of the fourth main group element tin. Carry out the preparation of carrier first, soak and calcinate the alumina ball in cerium chloride to obtain the catalyst carrier treated with rare earth; after spraying active components such as palladium, cerium, tin on the carrier, obtain the hydrogenation catalyst carrier of the present invention through activation catalyst.

[0014] The C5 distillate by-product of ethylene cracking is used as raw material, after raw material pretreatment, polymerization, neutralization and water washing under the action of aluminum trichloride catalyst, the crude C5 petroleum resin is placed in a reactor equipped with a hydrogenation catalyst, After removing impurities such as dechlorination at 280°C, carry out hydr...

Abstract

The preparation process of C5 hydrogenated petroleum resin with the C5 fraction as the side product of cracking ethylene includes the steps of: pre-treating material, neutralizing, water washing, eliminating chlorine ion impurity from crude resin product at 200-300 deg.c under the action of modified alumina as catalyst, and hydrogenation at 150-350 deg.c and 6.0-20.0 MPa in the presence of hydrogenation catalyst. The hydrogenation catalyst is prepared through spraying process and consists of catalyst carrier alumina 100 weight portions, Pd 0.2-1.2 weight portions, transition metal 0.06-0.48 weight portion, RE metal 0.001-0.05 weight portion and IV element 0.06-2.4 weight portions. The present invention is used in producing C5 hydrogenated petroleum resin with the material possessing relatively high cyclopentadiene and arene content.

Description

Technical field [0001] The present invention relates to the preparation method of mixed carbon five hydrogenated petroleum resin, especially relates to the preparation of carbon five by-products of piperylene, isoprene, cyclopentadiene, pentene and other mixed carbon five fractions as raw materials The preparation method of hydrogenated petroleum resin. Background technique [0002] C5 petroleum resin is a low-molecular-weight thermoplastic resin, which is polymerized by the by-product C5 fraction of ethylene plant under the action of aluminum trichloride and other catalysts. The average molecular weight is between 1000 and 3000. Resin has good compatibility, mixed with other substances, has good water resistance, acid resistance, low melting point, and good adhesion. Petroleum resin is mainly used as adhesives, road marking paints, rubber additives, coatings and inks. C5 petroleum resin generally has defects such as dark hue, bad smell, low thermal stability and oxidation ...
