摘　　要：本文利用抗水性能良好且能将水和硫化氢分离度很大的Hayesep-T作为预柱,GDX-301作为主分离柱,通过控制切阀的时间,使硫化氢和羰基硫进入主分离柱GDX-301,同时全部水分却被反吹预柱Hayesep-T柱,并配合程序升温,使预柱中的水分充分被洗脱出预柱。通过与目前普遍使用分析方法做对比试验,发现利用本文中提出的分析方法测量水煤气中硫化氢、羰基硫含量时既克服样品中含水带来的一系列问题,又操作简洁,且测量结果重复性和准确性大幅度提高,能满足现代煤制烯烃化工厂实际生产的需要。Hayesep-T was used as pre-separating column and GDX-30 as main separating column in this paper to separatehydrogen sulfide and carbonyl sulfide in GDX-301by controlling the valve-switch,and the water was blown out of Hayesep-Tat the same time coupled with programming heating. This method can not only resolve the problems of samples carrying water indetection of H2S and carbonyl sulfide in water gas,but also operate easily,the repeatability and accuracy of the testing results areimproved as well,which can meet the requirements of modern coal to olefin plants.
