Abstract

Highlights: HT process research and development for fast pyrolysis bio-oil continues to advance. Precious metal catalysis is a current focus, but long-term operation is unproven. Sulfur content of bio-oil and its effect on HT catalysts remains a key uncertainty. Paths to integrate bio-oil HT into existing refining infrastructure need elucidation. Abstract : This review addresses recent developments in biomass fast pyrolysis bio-oil upgrading by catalytic hydrotreating. The research in the field has expanded dramatically in the past few years with numerous new research groups entering the field while existing efforts from others grow. The issues revolve around the catalyst formulation and operating conditions. Much work in batch reactor tests with precious metal catalysts needs further validation to verify long-term operability in continuous flow systems. The effect of the low level of sulfur in bio-oil needs more study to be better understood. Utilization of the upgraded bio-oil for feedstock to finished fuels is still in an early stage of understanding.
