THERMOLYTIC SOLVENT EXTRACTION OFBIOMASS TO PRODUCE HEAVY OILS IN HIGHYIELD WITH LOW OXYGEN CONTENTS

摘要

It is recognized that bio-oils obtained by fast pyrolysis processes are not compatible with existing petroleum products due to their hydrophilic and acidic nature arising from their oxygen contents. The thermolytic solvent extraction of biomass offers a promising route for producing oils in high yield that are compatible with petroleum streams without the need to employ high pressure catalytic hydrogenation to facilitate high levels of oxygen removal.
