燃料酒精制备研究

该研究在传统发酵制备燃料酒精基础上,根据原料成分与影响发酵因素,在实验中添加果胶酶和植酸酶;结果表明:添加果胶酶6 U／g原料,作用时间30 min,植酸酶7 U／g原料时,使酒精度提高1．6％(v／v),原料出酒率提高3．9％,降低生产成本4．3％,同时缩短发酵时间8hr,从而有效降低生产燃料酒精成本;经济效益分析表明:这是一种切实可行燃料酒精制备工艺。

Study on the Produce of Fuel Alcohol

This experiment are based on the traditional experiment, according to compositions of the raw materials and the influencing factors of fermentation, we added pectinase and phytase. The result showed that: pectinase 6 U/g, added in the pretreatment of mixture, and the action time was 30 min, phytase 7 U/g, added during the fermentation, as a result, it could remarkably increase alcohol content by 1.6%(v/v), output rate of materials by 3.9%, and reduce about 4.3% production cost, meanwhile, shorten fermentation time for 8hr, so it effectively cut the production cost down. By the economy benefit analysis: this process is showed to be a fesible way to produce fuel alcohol.
