摘要:
报道了植物油在KOH 为催化剂的作用下通过甲醇酯交换反应生成脂肪酸甲酯即生物柴油的试验研究。考察了反应条件 如原料油、醇油比、催化剂用量、反应温度、反应时间等的变化对转化率和产品纯度的影响。采用气相色谱法测定反应体系中 脂肪酸甲酯的含量。应用正交实验的方法找出精棉籽油酯交换反应的最佳反应条件为:反应温度45 ℃, 醇油物质的量比6∶1 , 催化剂用量1.1 %, 反应时间60 min 。在此反应条件下原料油转化率可达98.33 %, 粗产品得率可达99.83 %。实验放大所得的 生物柴油主要质量指标已达到
Abstract:
A research was reported that biodiesel was manufactured by the transesterification of vegetable oils. Vegetable oils were readily transesterified batchwise with an excess of methanol at atmospheric pressure and at a temperature of approximately 45 ℃in the presence of KOH as catalyst .Through orthogonal analysis of parameters in a four -facto r and three -level test ,the optimum conditions were obtained for the t ransesterification : molar ratio of methanol to oil 6∶1 , usage amount of KOH 1.1 %and reaction temperature 45 ℃.Vegetable oil led to a 98.33 %conversion , and the yield of crude esters w as 99.83 % under these conditions .The propert ies of manufactured biodiesel oil had a quality specification near that of biodiesel oil f rom ASTM .
