Decarboxylation of Coconut Methyl Ester (CME) to form hydrocarbons was performed using calcium carbonate (CaCO3) as catalyst. The following parameters were tested: temperature (150°C and 180°C), catalyst loading (20% and 40%), and percent solvent ( Moreover, analyses showing a decrease in the amount of CME in the liquid product and evolution of carbon dioxide in the gaseous product, confirmed that decarboxylation happened. Parametric study revealed that the percentage reacted of CME can be further increased using the following conditions: temperature at low setting (150°C), catalyst loading and percent solvent at high settings (40% catalyst-to-feed w/w and 87% solvent in the mixture, respectively). It was also found out that the most influential factors are catalyst loading and percent solvent.
