HYDROISOMERIZATION CATALYST, PROCESS FOR PRODUCING THE SAME, METHOD OF DEWAXING HYDROCARBON OIL, AND PROCESS FOR PRODUCING LUBE BASE OIL

摘要

A hydroisomerization catalyst of the present invention is obtained by calcining a catalyst composition containing an ion-exchanged molecular sieve or a calcined product thereof, and at least one metal selected from the group consisting of metals of Groups 8 to 10 in Periodic Table of the elements, molybdenum and tungsten, carried on the ion-exchanged molecular sieve or the calcined product thereof, wherein the ion-exchanged molecular sieve is obtained by ion-exchanging a molecular sieve, which includes nanocrystals having a pore structure of ten-membered rings or eight-membered rings and having a ratio of the pore volume to the external surface area ([pore volume]/[external surface area]) of 2.0×10 -4 mL/m 2 to 8.0×10 -4 mL/m 2 and contains an organic template, in a solution containing a cationic species.
