High temperature solid-catalyzed in-situ transesterification for biodiesel production
Nur Syakirah Talha1, Sarina Sulaiman2, Azlin Suhaida Azmi3.
In-situ transesterification method is a simplified method for biodiesel production where
the oil was simultaneously extracted and transesterified into alkyl ester in-situ in one
single process. This process combines the steps of lipid (oil) extraction and
transesterification. The alcohol used was methanol as it is widely available and
economically feasible. In this study, in situ transesterification was conducted using solid
coconut waste and a novel heterogeneous catalyst synthesized from eggshells and
solid coconut waste by calcination. Reaction temperature, catalyst loading, and
methanol to solid ratio were varied from 70 to 120ËšC, 0.5 to 10.5 wt %, and 8:1 to 12:1
respectively. Meanwhile, reaction time was fixed to 3 hrs. Heterogeneous catalyst can
help to reduce the steps in separation and purification of the product. Moreover, utilizing
waste in the production can lower the production cost as well as help to save and clean
the environment. The highest biodiesel yield was observed at the condition of 95ËšC, 0.5
wt % catalyst, and 10:1 methanol to solid ratio.
