氧化铝基硫磺回收催化剂对SO_(2)的吸附脱附性能研究

Research on SO_(2) Adsorption and Desorption Performance by Al_(2)O_(3) -based Sulfur Recovery Catalyst

硫磺回收催化剂的活性对硫磺回收生产的影响很大。通过对氧化铝基硫磺回收催化剂进行干燥处理、蒸汽处理、无处理和失活处理后,分别通入SO_(2)进行室温吸附和程序升温试验,以考察其对SO_(2)的吸附和脱附性能,从而为硫磺回收催化剂的开发和应用提供技术支撑。

The activity of sulfur recovery catalyst poses significant influence on the sulfur recovery operation.After drying treatment,steam treatment,non-treatment and deactivation treatment of the Al_(2)O_(3)-based sulfur recovery catalyst,SO_(2) is introduced respectively for room-temperature adsorption and programmed temperature-rise experiment,to examine its SO_(2) adsorption and desorption performances,in order to provide technical support for the development and application of sulfur recovery catalyst.
