Abstract：
Bifunctional catalysts of sulfonic acid carbon materials supported Ru were prepared, with different carbon source precursors, namely, cellulose derived carbon, actived carbon and mesoporous carbon materials CMK-3 under different sulfonic acid conditions. The structures of catalysts were characterized by FTIR spectrum, XRD, elemental analysis, thermogravimetric analysis and N2 physical adsorption-desorption. The catalytic performance of hydrogenation reactions of cellulose were studied. Results show that, compared with cellulose derived carbon, activated carbon and mesoporous CMK-3 sulfonic acid carbon materials possess good combination ability with —SO3H，high catalytic activity and good polyols selectivity. Under 170 ℃ for 10 h, hexitols can yield up to 84.0%. When recycled, catalytic activity of activated carbon sulfonic acid materials supported Ru catalyst decreases, but keeps on selectivity of polyols; mesoporous carbon sulfonic acid materials supported Ru catalyst has problems with the loss of S, and conversion rate remaines about the same, but the product selectivity is reduced.
