Abstract: LS-951T catalyst developed by Research Institute of Qilu Petrochemical Company is a new hydrogenation catalyst for treating sulfur recovery tail gas. LS-951T catalyst, with the advantages of uniform distribution of active components, light bulk density and high hydrogenation activity, has a good applicability. The properties of the catalyst and the commercial processes of catalyst loading, presulfurization in a 380kt/a sulfur recovery tail gas unit in Sinochem Quanzhou Petrochemical Co.，Ltd were described. The performance of the catalyst was examined and compared in low and high load operation case．The loading pattern of LS-951T catalyst was modified because it’s easy to flow in the later case. The application results after modification of loading show that the catalyst presents good hydrogenation activity ever if in high load case. The SO2 content is less than 300mg/m3 in the treated gas, lower than the country’s emission standard of 960mg/m3.
