摘　　要：本文介绍了以焦炉气中自有的ＮＨ＿３为碱源，在ＰＤＳ（双核酞菁钴磺酸盐）的催化作用下，脱除煤气中Ｈ＿２Ｓ、ＨＣＮ的工艺模拟研究，提出了新的焦炉气净化工艺流程，称为Ａ－ＰＤＳ工艺。选择出了适宜的工艺条件，可将煤气中Ｈ＿２Ｓ由５～７ｇ／ｍ￣３脱至２０ｍｇ／ｍ￣３以下，脱除率达９９％以上；可将ＨＣＮ由０．８～１．３ｇ／ｍ￣３脱至２０ｍｇ／ｍ￣３以下，脱除率达９８％。A new process of purifying coke over gas (COG),named A-PDS process,has been developed.In which the PDS(Dinuclear Cobalt Phthalocyanine Sulfonate) wasused as catalyst and the ammonia in COG itself as alkali source for removing its H_2S andHCN. In model tests,high removing efficiency were obtained.
