Catalytic deoxygenation by H-2-free single-step conversion of free fatty acid feedstock over a Co-Ag carbon-based catalyst for green diesel production
A family of activated carbon-supported Co-Ag catalysts, synthesised through incipient wetness impregnation, have been evaluated for the deoxygenation of palm fatty acid distillate (PFAD) and inedible feedstocks (jatropha oil and waste cooking oil) to green diesel. High deoxygenation efficiency and c...
