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

• A review on biomass pyrolysis oil using shape selective microporous zeolites. • Historic evaluation of research was analyzed using bibliometric analysis. • Reaction pathways for different zeolites for bio-oil upgradation are presented. • Challenges and recommendation suggested the way forward. 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. [ABSTRACT FROM AUTHOR]
