摘要/Abstract

摘要： 向模拟煤层气(13.11vol% CH4+86.89vol% N2)中添加5.8mol%四氢呋喃(THF)?0.03mol%十二烷基硫酸钠(SDS)促进剂溶液分离提纯煤层气，考察了压力、温度、反应时间对气体消耗量、反应速率、分解气中甲烷浓度、甲烷回收率和甲烷分离因子的影响，采用色谱分析法分别测定了CH4在剩余气相和分解气相中的浓度。结果表明，压力增加，CH4回收率增大，CH4分离因子增大，CH4分离效果越好；温度是影响甲烷分离因子的关键因素，温度降低，氮气和甲烷竞争进入水合物晶体中，导致水合物相中甲烷浓度降低；温度升高有利于提高水合物对甲烷的选择性。甲烷回收效率最高可达98.65%，分离因子最大为14.83。随反应时间增加，分解气中CH4浓度升高。
