1、油脂类原料的生物炼制技术 生物法联产生物柴油和1,3-丙二醇技术进展,清华大学化工系 刘德华 2008.7.5,注：为单/双甘酯的生产路线，分别为： 甘油解； 不完全醇解； 不完全水解； 酯化,油脂类原料的生物炼制技术方案,生物酶法生产生物柴油新工艺利用生物柴油副产物甘油生产1,3-丙二醇,生物柴油简介,+,生物柴油是指由动植物油脂（大豆油、菜籽油、棉籽油、动物油、废食用油等）与一些短链的醇（常用甲醇）在催化剂的作用下发生转酯反应后，生成的长链脂肪酸酯类物质。,生物柴油生产方法,反应速率快； 油脂里的游离脂肪酸及水 严重影响生物柴油产率及品质反应速率快，转化率高； 无污染； 高温高压；反应条件
2、温和，醇用量小； 无污染物排放； 产品分离回收方便；催化剂成本高,酸/碱,脂肪酶,清华大学发明的新工艺（国际专利）可以完全解除甲醇和甘油对脂肪酶的抑制，成百倍地延长酶的使用寿命,符合美国、欧盟、中国生物柴油标准,中国石化检验报告,中国石化质量检验结果,利用清华大学的技术 以上油脂油料都能很好地转化成生物柴油,已尝试过的油脂原料： 大豆油 菜籽油 棉籽油 小桐子油 乌桕油 桐子油 橡子油,猪油 鱼油 米糠油 废油 海藻油 酵母油脂,From: Robert and Joanie Peters To: Rambo Smith Cc: Jason Du Sent: Thursday, Decembe
3、r 7, 2006 10:42:05 AM Subject: Rivers Sample Test Rambo,Congratulations! WCC Manager of Chemical R&D, Tim Ely, reported to us yesterday that his test of your sample was the “best that he had seen in his life”. “It is just an outstanding esther”, eventhough it was derived from waste oil. Tim did not
4、believe that this was possible. This is a very impressive vote of confidence for Professor Lius process. I am also really impressed with this testimonial. The meeting went well with Jason being very well prepared in his technical presentation. I believe that our projects are on target and on track.
5、I look forward to working with you to make them a success.Best Regards, ROBERT W. PETERS By: Robert W.

6、n.ch; duwei 主题： Dear Prof. Liu,I am pleased to inform you that the company (Mr. K. Pettas) which is interested in your biodiesel technology has carried out tests on the biodiesel sample you sent me and found it good. This opens the way for further cooperation. Congratulations to you and to your part
7、ners. The company is producing about 40.000 ton biodiesel per year using inorganic catalysis. Mr. Pettas wants to examine the case of making the absolutely necessary changes in order to alternatively use inorganic or enzyme catalysis for biodiesel production with minor changes in the process. That will be very important for him. How do you think it can be managed? Please be kind enough to send me your reply promptly.Best regardsB. J. Macris,
