Pt-Sn Catalysts for Biomass Conversion into Fuel Components and Chemicals
In TIPS RAS was found that ethanol and rapeseed oil could be converted into a number of fuel hydrocarbons over industrial Pt/Al2O3 catalyst. Aim of the current work is ethanol and rapeseed oil high selective conversion into fuel components and monomers over Pt-Sn/Al2O3 catalysts with different molar ratio of active components.
The most prospect catalyst for ethanol and rapeseed oil conversion was found to be 1Pt-5Sn/Al2O3. Over that carbon mass of initial oil could be converted into alkanes and olefins with only two C18 and C3-C4 fractions. So selective process may be only when oxygen of initial oil converts in water. Optimal conditions for ethanol conversion were found, that provides yield of alkanes and olefins C3-C8 up to 50 wt.%. Obtained results allow minimizing loss of initial carbon weight due to cancelation of carboxyl fragment of fatty acids and glycerol conversion into methane and carbon oxides.
