Production of bio-jet fuel from triglycerides (TGs) based vegetable oils have recently received increased attention from research and industries because of its renewability and environmental benefits. Catalytic deoxygenation (DO) is a suitable way to produce bio-jet fuel from TGs. Presently, the main challenges faced by DO are the optimized selection of feedstocks, catalysts, reaction pathways and parameters. This review includes discussion on the feedstock and assessment of several potential catalysts: noble metals, sulphided, non-sulphided for DO of TGs. This assessment elucidates the model compounds of TGs, effect of operating parameters, potential catalysts and different DO reaction pathways to attain optimum yield and selectivity of desired products. In addition, some relevant discussion of TGs derived jet fuel specification, characteristics and fuel properties are also discussed. Overall, this review provides a comprehensive discussion on DO of TGs based vegetable oils in enhancing alternative jet fuel production in all relevant technical aspects.
