Hydrogen is typically present in the reaction atmosphere, resulting in the hydrogenation of any double bonds including the terminal olefins produced via decarbonylation, which makes the liquid products resulting from decarbonylation and decarboxylation indistinguishable. Many of the drawbacks associated with biodiesel stem from the high oxygen content of fatty acid methyl esters (FAMEs), which can be higher than 10 wt% Therefore, research has aimed to develop processes that convert animal fats and plant oils to fuel-like hydrocarbons by removing the oxygen from these feeds via catalytic cracking, hydrodeoxygenation (HDO), or decarbonylation/decarboxylation (deCOx). This chapter focuses on the most salient work performed to date on the deCOx of lipids involving heterogeneous catalysts. It discusses the most abundant lipid feed sources, certain heterogeneous catalysts that support Group 10, including bimetallic formulations containing these metals. Developments to deCOx catalyst technology are promising.
