固体酸在生物柴油生产中的应用

Application of solid acid in production of biodiesel

随着石油资源的日益紧缺,生物柴油作为绿色可再生资源已经成为研究的热点。传统的生产工艺是以液体酸碱催化生产。随着人们环保意识的增强,人们正研究用固体酸碱替代液体酸碱。对固体超强酸、负载型固体酸、无机盐类、金属氧化物、树脂、金属螯合物、改性分子筛等催化剂在生物柴油生产中的应用及制备进行了介绍,以期为生物柴油催化剂的研究提供借鉴。

With the increasing shortage of petroleum resources, biodiesel as a environment - friendly and renewable resource has become the hotspot of study. In the traditional craft of biodiesel prodution, the liquid acid and base were used as catalysts. With the enhancement of environmental consciousness, the solid acid and alkali were used to substitute for the liquid acid and base. The application in the production of biodiesel and preparation of the catalysts of solid superacid,supported solid acid, inorganic salts, metal oxide compoundes, resin, metal complexes, modified - sieves and so on were introduced so as to provide reference for the study of catalysts used in biodiesel production.
