Yields of oil products from thermochemical biomass conversion processes

Abstract

Thermochemical biomass conversion processes, including mainly pyrolysis, liquefaction and supercritical fluid extraction, were applied non-catalytically and catalytically to obtain the maximum fuels from biomass. Different solvents and their mixtures were used in simple and supercritical extractions. Basic catalysts, such as NaOH, Na 2CO 3 and K 2CO 3, were used in catalytic conversion experiments. The experiments were performed within the 498–820 K range.
