Production of green biofuel by using a goat manure supported Ni–Al hydrotalcite catalysed deoxygenation process

The high oxygen content in natural biomass resources, such as vegetable oil or biomass-pyrolysed bio oil, is the main constraint in their implementation as a full-scale biofuel for the automotive industry. In the present study, renewable fuel with petrodiesel-like properties was produced via catalyt...

In the present study, renewable fuel with petrodiesel-like properties was produced via catalytic deoxygenation of oleic acid in the absence of hydrogen (H 2 ). The deoxygenation pathway of oleic acid to bio-hydrocarbon involves decarboxylation/decarbonylation of the oxygen content from the fatty acid structure in the form of carbon dioxide (CO 2 )/carbon monoxide (CO), with the presence of a goat manure supported Ni-Al hydrotalcite (Gm/Ni-Al) catalyst.
