Abstract
The studies were aimed at the development of hydroisomerization catalysts based on nanosize molybdenum carbides. These catalysts were expected to be resistant to sulfur compounds and applicable for synthesis of low pour point diesel fuels similar in parameters to the fuel synthesized over platinum catalysts. Acidic supports were synthesized for these catalysts; the supports differ by the type of their porous structures, number and strength of Broensted acid sites; these were silicoaluminophasphate SAPO-31, zeolite ZSM-21, modified zeolite Beta, desalicided zeolite ZSM-5. Adsorption methods, TPD of ammonia, NMR, SEM techniques were used for studying physicochemical properties of the supports.
