Research Progress in Co-pyrolysis-liquefaction of Coal and Biomass

The co-pyrolysis-liquefaction of coal and biomass is one of the new methods to convert coal and biomass to fuel and chemical materials. The mechanism of co-pyrolysis-liquefaction, reaction kinetics, the synergy of coal and biomass, catalyst, processing technics and co-pyrolysis-liquefied products during the co-liquefaction of coal and biomass are mainly introduced in this paper. The fast co-pyrolysis of coal and biomass will be an important co-processing technology in the future. Promoting the quality of co-liquefied oil and reducing production costs for the application of the catalysts during the co-liquefaction of coal and biomass and the upgrading of co-liquefied products are pointed out. The co-liquefied oil of coal and biomass will be a substitute for the current petrochemical oil.
