Abstract
Transesterification, esterification, and esterification-transesterification (both one-step and two-step) for producing biofuels. The process may be enhanced by one or more of the following: 1) applying microwave or RF energy; 2) passing reactants over a heterogeneous catalyst at sufficiently high velocity to achieve high shear conditions; 3) emulsifying reactants with a homogeneous catalyst; or 4) maintaining the reaction at a pressure at or above autogeneous pressure. Enhanced processes using one or more of these steps can result in higher process rates, higher conversion levels, or both.
