The conversion of biomass into sustainable fuels and chemicals is essential for addressing environ-mental concerns,reducing the carbon footprint of the energy sector,enhancing energy security,and promoting economic and social development.Among various biomass feedstocks,triglycerides from diverse sources,such as vegetable oils,animal fats,and microalgal oils,are particularly suita-ble for producing sustainable hydrocarbon fuels and chemicals due to their low oxygen contents and highly paraffinic backbone in the fatty acid units,the structures of which are already quite sim-ilar to those of petroleum-derived hydrocarbons.This implies that relatively simple catalytic con-versions can effectively convert triglycerides into hydrocarbon products.In this Perspective,we will provide an overview on the hydroconversion of triglycerides into oxygen-free fuels,such as diesel and jet fuel,and value-added products such as lube base oil.In addition,we will discuss the im-portant structural properties of the required catalysts and the effects of different fatty acid compo-sitions of triglycerides for each conversion process in light of reaction mechanisms.
