摘　　要：以氢氧化铝干胶为主要原材料,经改性制备成三叶草型载体,采用钴钼共浸液浸渍制备硫磺尾气加氢LS-951催化剂。考察了LS-951催化剂的物化性质、尾气处理工艺流程及所用尾气加氢催化剂LS-951的装填、预处理过程及工业应用情况。结果表明,催化剂具有良好的低温活性,完全能满足硫磺回收装置尾气处理工艺的要求,经净化后的尾气总硫排放量一般在100mg/m3以下。LS-951 catalyst was developed for treating the tail gas of a 80 kt/a commercial sulfur recovery plant.The catalyst,which was clover in shape, was prepared from modified Al 2O 3 as carrier,and impregnated with cobalt-molybdenum solution.Its preparation method, chemical and physical properties, reactor packing pattern, catalyst pretreatment and plant flow diagram were described.Two years of continuous commercial application showed LS-951 catalyst was very active at relatively low temperatures.It could satisfactorily meet the requirements of tail gas treatment unit of sulfur recovery plant.The total sulfur content in effluent gas was below 100 mg/m 3.
