Box Behnken Design

Ethyl acetate as acyl accepter have been used for sewage sludge biodiesel production in micro packed bed reactor. Lipase acrylic resin enzyme activity was investigated in the interesterification reaction of converting the sewage sludge into a biodiesel product. The main parameters affecting the process was adjusted via the design of Box-Behnken and approach of response surface then the optimum conditions were as follow (reaction time=15 h, ethyl acetate/oil ratio=24:1, temperature=40 °C and enzyme quantity=18 wt%) providing 95.78 % biodiesel yield. The lipase acrylic resin was examined under the optimum conditions for the reusability. the flow effect and the heating process of the micro packed bed reactor was investigated. The product biodiesel physicochemical properties were evaluated according to the ASTM D-6751-2 and found acceptable comparable to the mineral diesel properties.
