Catalytic conversion of biomass-derived hydrocarbons into industrially important chemicals over solid Lewis acid

 Renewable biomass resources have the potential to serve as a sustainable supply of fuels and chemical intermediates. The purpose of this study is to develop an environmentally benign and energy effective system to convert biomass-derived carbohydrates into value-added chemical resources (furans and organic acid) by using solid catalysts.
