Abstract

本发明提供一种脂肪酸转化工艺，将油脂与甘油混合，加热到55摄氏度左右，采用脂肪酶作为催化剂，使油脂中的游离脂肪酸与甘油发生酯化反应，从而将油中FFA转变成甘三酯，这样减少脱酸工艺，并可以提高酯产量。

Description

脂肪酸的转化方法
技术领域
本发明涉及一种生物柴油技术，尤其生物柴油的脂肪酸转化的工艺。
背景技术
目前的油脂的转化技术中，在油脂与甲醇进行酯交换反应中，1摩尔油脂与3摩尔甲醇反应，生成3摩尔甲酯和1摩尔甘油；而在脂肪酸与甲醇的酯化反应中，1摩尔脂肪酸与1摩尔甲醇反应生成1摩尔甲酯和1摩尔的水。这样生成的水会稀释反应物甲醇的浓度，从而使甲醇产量大大降低，并减缓反应速度。
目前去除脂肪酸的处理方式就是采用化学方法中和皂化去除脂肪酸的方法，这样会增加工艺流程和其他投入成本，而且也造成脂肪酸的浪费。
发明内容
本发明提供一种脂肪酸转化生物柴油的工艺。
为实现上述目的，本发明的技术方案是：
一种脂肪酸转化工艺，其特征在于将油脂与甘油混合，加热到55摄氏度左右，采用脂肪酶作为催化剂，使油脂中的游离脂肪酸与甘油发生酯化反应，从而将油中FFA转变成甘三酯。
这样减少脱酸工艺，并可以提高酯产量。
具体实施方式
具体实施中，也可以采用210摄氏度的温度，采用氯化锌为催化剂，使过量的甘油与油脂中的游离脂肪酸进行酯化反应，使游离脂肪酸变成甘三酯，另外，需求采用高度真空环境，在600～800Pa之间。

Claims (2)

1.一种脂肪酸转化工艺，其特征在于将油脂与甘油混合，加热到55摄氏度左右，采用脂肪酶作为催化剂，使油脂中的游离脂肪酸与甘油发生酯化反应，从而将油中FFA转变成甘三酯。
2.如权利要求1所述，其特征在于采用210摄氏度的温度，采用氯化锌为催化剂，使过量的甘油与油脂中的游离脂肪酸进行酯化反应，使游离脂肪酸变成甘三酯，另外，需求采用高度真空环境，在600～800Pa之间。
