| 摘 要： | 通过棉籽现场碱催化转酯化联产生物柴油和无毒棉粕，考察了棉仁中水的质量分数、粒径对产物中脂肪酸甲酯（FAME）的质量分数和棉粕中游离棉酚（FG）质量分数的影响；对反应过程中的醇油摩尔比、反应时间、催化剂用量、反应温度进行了单因素和正交实验考察。实验得到的反应适宜条件为，棉仁含水量在1.92%左右，棉仁粒径小于0.335mm，反应醇油摩尔比135∶1，反应3h，甲醇中氢氧化钠浓度0.10mol/L，反应温度30℃。在上述反应条件下，反应产物中甲酯的质量分数可达97%，棉粕中游离棉酚的质量分数为0.031%，低于FAO规定的国际标准。

| Abstract: | The production of biodiesel and nontoxic cottonseed meal by in-situ alkaline-catalyzed transesterification of the triglycerides(TG) in the cottonseed was investigated.The effect of the moisture content and particle size of cottonseed flour on the fatty acid methyl ester(FAME) content in the biodiesel and free gossypol(FG) content in the cottonseed meal was investigated.The reaction conditions including the molar ratio of methanol to oil,amount of alkaline catalyst used,and reaction temperature and time were... |
