Abstract

Enzyme-catalyzed transesterification is a valid alternative to diminish the disadvantages related to the use of chemicals to catalyze the transesterification reaction for biodiesel production. Processes catalyzed by enzymes are less energy-intensive and more environmentally friendly, assuring higher compatibility with different raw materials and better product separation. The biggest drawback for the use of enzymes is their high cost. In order to be economically competitive, enzyme-catalyzed routes need to be optimized. An alternative to reduce the operating costs and prevent wastes is to reuse the enzymes. However, reuse of liquid enzymes is restricted by the difficulty of separating them from the reaction medium. Ultrafiltration by ceramic membranes is a novel alternative to their recovery eliminating substances that inhibits the enzymes thus improving the efficiency of the enzyme reuse. To complete the process analysis, process optimization should be combined with an environmental impact assessment.
