BEI debuts enzymatic biodiesel processing

April 4, 2011 |

In Texas, Biodiesel Experts International relates that it has developed a process – and will provide engineering, onsite supervision, startup, training, enzyme material, and complete plants – for an enzymatic process to convert waste oils or greases into ASTM spec biodiesel.

“The enzymatic process consist of two different types of enzyme, one for transesterification and one for esterification,” BEI’s Ernie DeMartino advised the Digest.  “Feed stocks with 0-100 FFA can be processed at an operating temperature of 85 F with minimal methanol required.  No caustics are required and there is no soap formation.” According to BEI, existing biodiesel plants can be re-engineered to utilize the process.
