Continuous Biodiesel Production with Continuous Liquid-Liquid Extraction and Online MS Analysis

Abstract: Biodiesel is an alternative fuel for diesel engines that is gaining attention in the US. Its advantages are that: it is a renewable fuel; it is non-toxic and is biodegradable and can be used in diesel engines without requiring extensive engine modification.

Biodiesel production involves the conversion of triglycerides into fatty acid esters, typically under Zemplén conditions. The rate limiting step in these reactors is not chemical kinetics, but mass transfer due to the immiscibility of the vegetable oil and the alcohol. The shear forces in the stirred tank reactors are not sufficient to effectively mix the two phases.
