The impact of operating conditions on H2-free catalytic deoxygenation of triglycerides for bio-jet fuel synthesis: A step towards sustainable aviation

Sustainable aviation fuels (SAFs) provide a vital pathway to reduce emissions from the growing aviation sector. Taking this inspiration, this review critically examines recent progress in the catalytic deoxygenation (DO) of triglycerides (TGs) feedstocks to produce renewable jet fuel without external hydrogen (H2) requirements. The effects of various key parameters are analysed in terms of its selectivity, efficiency and production yields. The choice of catalyst can be regarded as the most significant parameter followed by the temperature then the feedstock. This review provides an up-to-date examination of this emerging technology area and its status in overcoming barriers to viable aviation biofuel production.
