THE METHOD OF MANUFACTURING THE CONTAINING NOBLE METAL OF A HYDROGENATION CATALYST, CONTAINING A NOBLE METAL OF A HYDROGENATION CATALYST AND ITS APPLICATION

摘要

A method of manufacturing a noble metal containing hydrogenation catalyst is described, including the manufacture of a carrier from a molecular sieve having a 10-membered ring structure and / or an amorphous porous material; the manufacture of an impregnating solution containing a noble metal from one or more compounds of the noble metals Pt, Pd, Ru, Rh, Re and Ir of ideionized water or an acidic solution; and the manufacture of impregnating solutions containing noble metal with deionized water with a concentration gradient of 0.05 to 5.0% by weight, and successive impregnation of the carrier with impregnating solutions from low to high concentrations during the impregnation process of the carrier or the manufacture of impregnating solution containing the noble metal having a low concentration of 0.05 to 0.5 wt.%, and impregnation of the carrier with a gradual increase in the concentration of the noble metal containing its solution to from 2.0 to 5.0 wt.% in the process of impregnation, and then homogenizing, drying, and calcining, as well as containing a noble metal hydrogenation catalyst, its application and method of manufacturing a lubricant base oil. The catalyst according to the present invention has high activity and stability, and the lubricant base oil produced exhibits a high viscosity index and a low pour point.
