Influence on H_2S desulfurize by the compound desulfurizer of attapulgite clay andactive metal oxide

This paper introuduces the compound desulfurizer of attapulgite clay and active metal oxide.The effects of such factors as the contents of attapulgite clay and active metal oxide,and roast temperature on desulfurizion efficiency and sulfur capacity of the compound desulfurizer in removing high concentration H2S at ambient temperature and pressure were studied.Its structure were analysed with IR,XRD and BET.The results showed that attapulgite clay as the major component with 20%～ 30% active metal oxide could achieve higher desulfurizion efficiency and large sulfur capacity of the compound desulfurizer for high concentration and low flowrate H2S.It has high stability and good performance of desulfurization and is suitable for removing H2S at ambient temperature.
