This study reports the selective obtaining of butanediols, mainly23BDO and 12BDO isomers, by C- O hydrogenolysis of erythritol on Ru (2%) supported on titania at 473 K and 25 bar H2 and their modification with Re species that improve the selectivity to C-O hydrogenolysis over other reactions (C-C hydrogenolysis, dehydration, etc). The dependence of the catalytic activity with reaction temperature and reactants concentrations is also discussed. Characterization by XPS, TEM and TPR indicates that the surface of rhenium modified Ru is formed by small particles (
