摘　　要：为探究文冠果油在生物柴油产业中应用前景,以SO_(4)^(2-)/ZrO_(2)-CeO_(2)-杭锦2#土(SZCe-HJ)为催化剂,采用中心复合(CCD)实验设计方法,通过改变对生物柴油产率影响最大的四个因素:反应时间-X_(1)、醇油摩尔比比-X_(2)、催化剂用量-X_(3)和反应时间-X_(4),考察生物柴油产率-Y的变化,并对实验数据进行拟合,建立数学模型。研究结果表明:该模型能够准确估算SZCe-HJ催化文冠果油制备生物柴油的产率。醇油摩尔比达到8.21:1、催化剂用量达到2.66 wt.%、反应时间持续8.65 h,生物柴油产率最高将达到62.76%。To investigate the potential application of Avena sativa oil in the biodiesel industry,we utilized SO_(4)^(2-)/Zr O_(2)-CeO_(2)-Hangzhou 2#soil(SZCe-HJ)as a catalyst.The central composite(CCD)experimental design method was employed,with the reaction temperature(X_(1)),alcohol-oil molar ratio(X_(2)),catalyst dosage(X_(3)),and reaction time(X_(4))as independent variables.The biodiesel yield(Y)was considered as the response value,and a mathematical model was established byfitting the experimental data.The results demonstrated that the model accurately predicted the biodiesel yield of SZCe-HJ-catalyzed Avena sativa oil preparation.The optimum conditions for maximum yield were found to be an alcohol-oil molar ratio of 8.21:1,catalyst dosage of 2.66 wt.%,and reaction time of 8.65 h.Under these conditions,the highest biodiesel yield achieved was 62.76%.
