摘要

Processes for reducing water in a pyrolysis oil derived from biomass containing water, and to prepare for pyrolysis oil derived from biomass with low water content, and pyrolysis oil derived from biomass with low water content. Pyrolysis oils derived from biomass containing low water content and processes for their preparation are provided.The pyrolysis oil derived from biomass containing water is distilled in the presence of a liquid azeu00f3tropo maker to form a azeu00f3tropo. The azeu00f3tropo is removed at or above the boiling point of the azeu00f3tropo and pyrolysis oil derived from biomass with low water content is obtained.
