| description | A recent rise in crab aquaculture activities has intensified the generation of waste shells. In the present
study, the waste shells were utilized as a source of calcium oxide to transesterify palm olein into methyl
esters (biodiesel). Characterization results revealed that the main component of the shell is calcium carbonate
which transformed into calcium oxide when activated above 700 �C for 2 h. Parametric studies have been investigated and optimal conditions were found to be methanol/oil mass ratio, 0.5:1; catalyst amount, 5 wt.%; reaction temperature, 65 �C; and a stirring rate of 500 rpm. The waste catalyst performs equally well as laboratory CaO, thus creating another low-cost catalyst source for producing biodiesel. Reusability results confirmed that the prepared catalyst is able to be reemployed up to 11 times. Statistical analysis has been performed using a Central Composite Design to evaluate the contribution and performance of the parameters on biodiesel purity. |
