Nowadays, products coming from biomass arise as raw material of organic fuels and chemical products. Particularly, the glycerol availability attained as bio-diesel byproduct has inspired the study of different applications. Hydrogenolysis of glycerol to PG has been previously reported to use several supported transition metal catalysts such as Ru, Pt and Cu including some bimetallic catalysts consisting of PtRu and Pt-Re. The bimetallic catalyst preparation from techniques derived from Surface Organometallic Chemistry on Metals SOMC/M is a field of chemistry devoted to the study of the reactivity of organometallic complexes with metallic surfaces. It is proposed in the present work to study the reaction of hydrogenolysis of glycerol under mild operation conditions (200°C and 16 bar N2 or H2 pressure) with bimetallic catalysts of Pt (1 wt%) and Sn (0.1 to 1wt%) supported on SiO2 prepared by SOMC/M techniques.
