Directly Catalytic Decomposition of H2S to Sulfur and Hydrogen under Microwave Conditions

摘要

The catalytic decomposition of hydrogen sulfide (H2S) under microwave heating was studied. The effect of microwave supply power on H2S decomposition rate was investigated over M0S2 catalyst and found that 100W was an optimal microwave supply power for this reaction. That is to say, the pathway of H2S decomposition under microwave conditions is different with that under conversional conditions. The activities of Co catalyst with different supports were also compared. The results show that under microwave heating conditions, comparing with Co/ZSM-5 and Co/X-zeolite, Co/5A has a higher activity for decomposition of H2S.
