Development of alternative approaches to fuel components and basic organic synthesis precursors producing based on biomass treatment products is important objective for ecology and chemistry. In the present work a number of original Pt-Sn containing catalysts were used for ethanol and rapeseed oil conversion. The peculiarities of used catalysts are usage of heterometallic precursors that possesses metal-metal bonds. Such kind of catalysts precursors allow obtaining more active and selective catalysts then ones based on a mixture of monometallic Pt and Sn precursors. Catalyst with molar ratio of Pt:Sn equal to 1:5 was the most prospective for ethanol conversion into alkanes and olefins C3-C8. Shown that over Pt-Sn containing catalysts rapeseed oil converts into alkanes or olefins C3-C18. The highest selectivity close to 100 % during rapeseed oil conversion into hydrocarbons C3-C18 was found to be over Pd-Sn/Al2O3 catalyst with Pt:Sn molar ratio equal to 1:5. Structural peculiarities of catalysts were characterized with X-ray diffraction and XAS technique. Relations between Pt clusters structure and its catalytic properties were determined.
