Catalytic hydrogenolysis reaction of 5-hydroxymethylfurfural platform molecule to produce 2,5-dimethylfuran conversion was studied. For that purpose noble metal(Pt and Ir) catalysts supported on SBA-15 and Ti-SBA-15 supports were used. All of the tested catalysts were able to convert completely HMF. However, among the mentioned catalysts, the bimetallic Pt-Ir catalyst supported on Ti-SBA-15 showed the best behavior in terms of DMF selectivity, probably due to Ti incorporation and the synergic effect with the noble metals. Moreover, this catalyst was studied in order to know the influence of some reaction parameters on DMF selectivity. As results obtained, the increment of the pressure and the bimetallic formation improved the DMF selectivity.
