Recent progress in catalytic deoxygenation of biomass pyrolysis oil using microporous zeolites for green fuels production

Abstract

Biomass pyrolysis is one of the cleaner ways to produce bioenergy focusing on bio-oil. The high oxygen content of oxygen in bio-oil limits its application in transportation applications. The deoxygenation of bio-oil using various catalyst systems is required to upgrade the bio-oil. Herein, we presented the scientometric analysis of microporous zeolites for deoxygenation of biomass-derived bio-oil. The state of the art review of biomass catalytic deoxygenation using zeolite-based materials is elucidated. A special focus on the role of catalyst physicochemical properties and degree of deoxygenation is Furthermore, the reaction pathways for different zeolites for bio-oil upgradation are presented. Finally, the technology readiness level is assessed and future recommendations are also presented.
