Prospects for using Mo- and W-containing catalysts in hydroisomerization: A patent review. II: Catalysts based on molybdenum and tungsten carbides

Abstract

Patent information on the production of catalytic systems containing molybdenum and tungsten carbides and their application in the hydroisomerization of paraffinic hydrocarbons is reviewed. Analysis shows that modifying acid supports with molybdenum and tungsten carbides solves the problem of creating a stable catalyst for the hydroisomerization of paraffinic fractions. The resulting catalyst is resistant to sulfurcontaining impurities in hydroisomerization feedstock.
