Bio-Diesel Production

Problem

In order to reduce dependence on finite fossil fuel reserves and decrease environmental pollution caused by petroleum diesel production, renewable energy sources such as biodiesel have been sought. However, traditional methods of biodiesel refinery utilize significant amounts of energy for thermal or catalytic cracking and create chemical and wastewater discharge as a consequence of water washing processes. This method also creates unwanted byproducts that require complex downstream processing for glycerol separation.

Solution

ESTER-ZYME LIPID© is a blend of selected enzymes for the esterification of edible and non–edible oils to produce biodiesel in the presence of a suitable solvent system. These enzymes are specific in activity and designed to work upon a wide range of fatty acids derived from various oil sources. ESTER-ZYME LIPID© is compatible with a wide range of temperatures and pH levels to suit various solvent systems at ambient pressure without the requirement for extreme conditions.

Benefits

There is no soap or no caustic formation and the process utilizes less than a tenth of the energy consumed in the traditional chemical process
Enzymes are specifically designed to catalyze esterification in low -water systems and in anhydrous organic solvent systems
The formulation can perform with high specificity and regioselectivity
Unlike the chemical processes, the enzyme application does not require removal of inorganic salts from the downstream processes
Systems are more efficient and specific in conversion of free fatty acid (FFA) content in the starting material leading to a highly pure product
Depending on the system, the enzymes can be separated from the liquid phase and recycled back into the reaction system
