Tóm tắt

Highly efficient and universal biomass conversion methods are described. Methods utilize a base-catalyzed decarboxylation reaction in a conversion process carried out in the presence of excess base to overcome carbonate formation from CO2. Methods can efficiently convert all components of a biomass feedstock to liquid hydrocarbons and carbon dioxide byproduct. The process has several versions: hydrolysis and alcoholysis, etc. The chemical process can be carried out with nearly 100% conversion for any type of biomass feedstock and requires no expensive or complicated pretreatment. The conversion reactions can be carried out at moderate temperatures of 170-300� C. and form a product that can include a mixture of hydrocarbons and oxygenated hydrocarbons, including alcohols and phenol derivatives.
