甲醇汽油的抗相分离性能研究

摘要

The paper studied several different volume fraction methanol gasoline's low temperature anti—separate property and water anti -separate property and identified three different phase separation inhibitor. By changing the addition amount of phase separation inhibitor,the paper studied the methanol gasoline's low temperature anti —separate property and water anti-separate property again,and compared the results with the raw methanol gasoline, found its optimum adding amount at the stable and uniform situation. So that it can meet the actual production requirements. The results show that the optimum adding amount is 4%(Volume).%考察了几种甲醇体积分数不同的甲醇汽油的低温抗相分离性能和遇水抗相分离性能,并通过在实验室进行的研究制备了3种不同的相分离抑制剂.通过改变相分离抑制剂的加入量,还考察了相分离抑制剂对甲醇汽油的低温抗相分离性能和遇水抗相分离性能的影响,并将其结果与未加相分离抑制剂的甲醇汽油的数据进行了对比.考察结果得知:所添加的相分离抑制剂的体积分数为4％时,甲醇汽油的相分离性能最好,能够满足实际生产需求.
