Title:
METHOD FOR HYDROGENATION CATALYSIS OF C9 RESIN
Document Type and Number:
WIPO Patent Application WO/2021/169015
Kind Code:
A1
Abstract:
Disclosed is a method for hydrogenation catalysis of a C9 resin, characterized in: 1) a Pt-W-Y/γ- Al2O3 catalyst is placed in the first half section of a fixed bed, a Pd-Zr-Nd/γ-Al2O3 catalyst is placed in the second half of the fixed bed, and hydrogen is introduced for reduction; and 2) a pre-treated C9 resin is subjected to hydrogenation catalysis in the fixed bed. Different catalysts that can react under the same catalytic conditions are placed in the first and second half of the fixed bed. The function of each of the two different catalysts have a different emphasis, but can be active under the same conditions and have complementary effects. The synergistic effect of the two catalysts has a good catalytic effect, which simplifies the production process and saves on production costs.
