Biodiesel production using lipase immobilized onto chitin in fixed bed reactor
Biodiesel is gaining considerable attention in recent years as a greener candidate to replace petroleum-based diesel. Biodiesel can be synthesized through a transesterification process of vegetable oils using lipase as a biocatalyst, but industrially the process remains economically not yet feasible...

description | Biodiesel is gaining considerable attention in recent years as a greener candidate to replace petroleum-based diesel. Biodiesel can be synthesized through a transesterification process of vegetable oils using lipase as a biocatalyst, but industrially the process remains economically not yet feasible. Thus, this study on biodiesel production was carried out using commercial lipase immobilized on chitin in a fixed bed reactor to obtain optimum conditions. Immobilized lipase with high immobilization degree was obtained through activation of chitin using glutaraldehyde for 1.5-hour, 0.22 mg/mL lipase concentrations, and 18 hours incubation time. The immobilized lipase was then used in the transesterification process to convert palm oil into methyl ester. The transesterification temperatures and the oil-to-methanol molar ratios were varied between 40 to 55 degrees Celsius and 1:3 to 1:6, respectively. The highest methyl ester conversion yield after 8 hours of reaction was obtained at 45 degrees Celsius using the oil-to-methanol molar ratio of 1:4. The stability of the immobilized lipase was investigated through a transesterification reaction in a fixed bed reactor for 50 hours without stopping. The highest conversion of methyl ester was obtained at the twelfth hour with a yield of 67.95%. |
