Valorization to hydrogen of bio-oil aqueous fractions from lignocellulosic biomass pyrolysis by aqueous phase reforming over Pt/C catalyst
Aqueous phase reforming was studied for the valorization to hydrogen of the aqueous fraction of bio-oil from lignocellulosic biomass pyrolysis. Aqueous phase reforming was carried out at 220 °C with a 3 % wt. Pt/carbon catalyst and an aqueous fraction of bio-oil feed containing 1 % wt. of organic ma...
