燃料乙醇作为车用清洁能源发展迅速。传统的粮食发酵法制乙醇路线经济性较差。目前,甲醇低压羰基化醋酸生产技术非常成熟,随着醋酸行业蓬勃发展,产能严重过剩,价格持续低迷。开发醋酸加氢制乙醇路线,不但能满足日益增长的燃料乙醇需求,还能延长醋酸产业链,缓解醋酸产能严重过剩问题,提升醋酸行业的经济效益,实现经济与社会效益双赢。
Fuel ethanol is rapidly developing as a clean energy vehicle. The traditional method of food fermentation ethanol route economic poor. At present, the methanol production technology of low-pressure carbonylation of methanol is very mature. With the booming development of acetic acid industry, the production capacity is in serious excess and the prices remain sluggish. The development of an acetic acid hydrogenation to ethanol route will not only meet the growing demand for fuel ethanol, but also extend the acetic acid industry chain, ease the serious problem of excess capacity of acetic acid production, enhance the economic benefits of the acetic acid industry and achieve a win-win economic and social benefits.
