METHOD FOR PRODUCING BIODIESEL FROM OIL EXTRACTED FROM GROUPER FISH VISCERA, CATALYZED BY A COMMERCIAL LIPASE AND ASSISTED BY ULTRASOUND.

摘要

The present disclosure is related to a novel method for producing biodiesel using oils extracted from fish viscera, as the raw material (commonly known as grouper). Methodologies related to the use of enzymatic catalysis have been found for the biodiesel production or, methodologies in which the use of chemical catalysis assisted by ultrasound technology is exposed. In the present application, the necessary conditions to carry out a transesterification of fish viscera oil is set forth using a commercial lipase as catalytic medium (such as N 435) solvent free, assisted by ultrasound technology with the application of low frequency of high intensity (40kHz) at atmospheric pressure, previously heating the reactive mixture at 45°C, obtaining a yield of up to 98%.
