Prospects for using Mo- and W-containing catalysts in hydroisomerization. a patent review. Part 1: Catalysts based on molybdenum and tungsten phosphides

Abstract

Patent information on methods used for preparing catalytic systems containing molybdenum and tungsten phosphides and employing these systems in the hydroisomerization of paraffinic hydrocarbons are analyzed. Analysis of the patent information shows that modifying acidic supports with molybdenum and tungsten phosphides allows us to create a catalyst for the hydroisomerization of paraffinic fractions that is stable and resistant to sulfur impurities contained in the hydroisomerization feedstock.
