HYDROISOMERIZATION DEWAXING CATALYST AND METHOD FOR PREPARATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2018/161950

Kind Code:

A1

Abstract:

Provided are a hydroisomerization dewaxing catalyst and method for preparation thereof; said hydroisomerization dewaxing catalyst is obtained by way of a catalyst carrier loading an active metal component in a soaking liquid, then drying and calcining, said soaking liquid containing Pt metal salt, a second metal ion Sm3+, and a third metal ion cerium Ce3+. The method for preparing the hydroisomerization dewaxing catalyst comprises the following steps: (1) preparing a catalyst carrier; (2) placing the catalyst carrier into a a soaking liquid and soaking, the soaking time being 2-24 h; (3) drying and calcining the soaked catalyst carrier to obtain a catalyst finished product. A second metal ion Sm3+ and third metal ion cerium Ce3+ are introduced into a soaking liquid containing Pt, thus performing a modification, forming a trimetallic complex cluster, greatly improving the dispersity of a noble metal on the surface of a carrier; the Pt load required by a catalyst prepared with the same hydroisomerization catalytic activity is reduced.
