| Popis: | Enzymatic catalysis for biodiesel production using low-cost, high-acid, lower-grade waste oils has attracted much attention recently due mainly to economic issues, renewability, and sustainable benefits. The performance of a commercial, low-cost lipase (Eversa®, Novozymes) was investigated in the hydrolysis and subsequent esterification reactions for fatty acid methyl esters (FAME) production. In order to reduce the costs of industrial enzymatic biodiesel production, enzyme was used in its soluble, free form. A model mixture comprising soybean oil with high free fatty acid (FFA) content (0, 25, 50, and 75 wt% oleic acid) and low-cost substrates such as non-edible macauba acid oil (Acrocomia aculeata) and waste cooking oil were employed for FAME production. FAME yields as high as 97% were reached using 2.5 wt% water, 1.5 methanol equivalent, and 1 wt% Eversa enzyme content in a 16-h reaction. The enzyme biodiesel process described in this study appears to be a promising alternative to the traditio... |
