| Summary: | 碩士 === 國立成功大學 === 化學工程學系碩博士班 === 97 === CaO, immobilized in chitosan beads by physical encapsulation, was employed as an alkali catalyst to catalytically produce biodiesel by transesterification of soybean oil with methanol. The operation conditions for CaO immobilization with high stability were optimized as the CaO loading of this catalyst was obtained around 12% (w/w). The immobilized CaO trapped in chitosan beads was further employed to investigate the transesterification reaction of soybean oil with methanol. The response surface methodology (RSM) was applied to determine the optimal catalytic reaction conditions at temperature of 60oC, molar ratio of oil to methanol of 1:13.4, and catalyst loading of 13.78 wt%. Under the optimal reaction conditions, the equilibrium conversion of soybean oil was up to 97% for 3 hours.
