摘要
Abstract
With molecular sieve NaY as carrier, supported solid base CaO/NaY was prepared by microwave irradiation, and the transesterification of soybean oil and methanol to produce biodiesel was investigated with the catalyst. The results show that the yield of biodiesel can be about 95% under the conditions when molar ratio of methanol to soybean oil is 9 : 1, catalyst mass fraction is 3%, reaction temperature is 65℃ and reaction time is 3 h. The CaO/NaY catalyst is more tolerant to free fatty acids and water, and the yield is 92.4% and 84.8% respectively when acid value (as KOH) is 4 mg/g and water mass fraction is 1.5%. Moreover, X-ray diffraction (XRD) analysis shows that CaO is well dispersed in NaY after microwave irradiation, and CaO/NaY is a kind of solid super base with total basicity of 3.798 mmol/g(H-≥27).关键词
