Candida antarctica lipase B (CALB) and Thermomyces lanuginose lipase (TLL) were co-immobilized on epoxy functionalized silica gel via an isocyanide-based multicomponent reaction. The immobilization process was carried out in water (pH 7) at 25°, rapidly (3 h) resulting in high immobilization yields (100%) with a loading of 10 mg enzyme/g support. The immobilized preparations were used to produce biodiesel by transesterification of palm oil. In an optimization study, response surface methodol. (RSM) and central composite rotatable design (CCRD) methods were used to study the effect of five independent factors including temperature, methanol to oil ratio, t-butanol concentration and CALB:TLL ratio on the yield of biodiesel production The optimum combinations for the reaction were CALB:TLL ratio (2.1:1), t-butanol (45 wt%), temperature (47°), methanol:oil ratio (2.3). This resulted in a FAME yield of 94%, very close to the predicted value of 98%.
International Journal of Biological Macromolecules published new progress about Biodiesel fuel. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate.
