Enhancing kinetics of biodiesel production using morpholine.

This work illustrates morpholine assisted transesterification of crude canola oil, corn oil and coffee oil (extracted from spent coffee grounds) using NaOH as a homogeneous base catalyst. Addition of morpholine resulted in a two-fold enhancement in kinetics of transesterification. The properties of the biodiesel final product were evaluated by fuel standard tests and the results were compared with ASTM D6751 standards. Biodiesel produced from canola, coffee and corn oils was found to have a high cetane number (52.5–55.1) and good flash point (140 °C). [ABSTRACT FROM AUTHOR]
