In this study, we produce biodiesel from jatropha oil through enzymatic synthesis in a re circulated packed bed reactor (PBR). A solvent free system by three stepwise addition of one equivalent molar methanol in each step was chosen for this study. The enzyme was Lipozyme IM, a 1, 3 regiospecific immobilized lipase from Mucor miehei. Initially, we scrutinized the appropriate amount of lipase by varied...
Biodiesel production catalyzed by Novozyme 435 was optimized using Plaekett-Burman design and response surface methodology. Firstly, Plaekett-Burman was employed to screen the main efficient parameters on conversion rate from enzyme dosage, reaction temperature, tert-butanol amount, oil/alcohol molar ratio and molecular sleves added amount. Then, the steepest ascent experiments were carried out to...
The transesterification of Jatropha oil and methyl acetate to biodiesel catalyzed by Novozym 435 (N435) was explored. The organic solvent and the factors of influenced reaction were optimized.The optimum reaction conditions were 6% of N435 based on the Jatropha oil weight, the molar ratio of n-hexane to Jatropha oil was 19, 10% of organic trihydroxymethyl aminomethane base on the Jatropha oil weight,...
The activity behavior of Novozym 435 treated with organic solvents was investigated, and the influence of several crucial parameters, including Novozym 435 dosage, oil to methanol molar ratio, reaction time and type of monohydric alcohol, on biodiesel yield was also addressed using tert-butanol as co-solvent. The results showed that the functional group as well as log P of organic solvents was an...
