Review of catalytic reforming of biomass pyrolysis oil for hydrogen production

After more than 20 years of development, biomass rapid pyrolysis technology has become technically mature. However, its main product biomass pyrolysis oil (bio-oil) has limited its application due to low energy density and poor thermal stability. Catalytic reforming is a workable way for bio-oil subsequent utilization to produce hydrogen. In this article, the research status and main research directions of bio-oil catalytic reforming for hydrogen production are summarized, with emphasis on CO 2 adsorption-enhanced catalytic reforming for hydrogen production.
