Development of Catalyst for Hydrodesulfurization of Coke Oven Gas

The experimental and test results for a coke oven gas hydrodesulfurization catalyst and the associated process were described.The key to application of coke oven gas as an economically advantageous feedstock for methanol synthesis is highly-efficient treatment of the gas for abatement of the hazardous impurities.Existing hydrodesulfurization(HDS) processes can only meet the requirement of ammonia plants with a total sulfur content <0.5×10-6 to 1×10-6.Modern high-efficiency methanol synthesis catalysts require that total sulfur in the synthesis gas be treated to as low as <0.1×10-6.The experimental results show that JT-1 and JT-8 HDS catalysts,developed by Northwest Research Institute of Chemical Industry,were applicable to HDS of coke oven gas with high CO and CO2 concentration,with high treatment efficiency and little side reactions.The total sulfur in the treated gas is as low as <0.1×10-6.
