摘　　要：研究了低温硫磺回收工艺克劳斯反应器在吸附和再生状态下催化剂性能的变化情况,并对吸附、再生时间与反应器温升/压差进行了定量回归分析。吸附阶段,催化剂活性中心随吸附液硫的增多而逐渐被覆盖,导致催化活性快速衰减。再生阶段,催化剂活性中心随吸附液硫的蒸发而逐渐暴露出来,活性快速恢复。通过增大催化剂孔道、减小催化剂颗粒热容,可延长反应器吸附时间,缩短再生时间,从而提高低温克劳斯工艺硫磺回收装置性能。Changes of catalyst performance in adsorption and regeneration state of Claus reactor in lowtemperature sulphur recovery process are studied. Quantitative regression analysis of adsorption,regeneration time and reactor temperature rise/pressure difference are carried out. During adsorption,active center of catalyst is gradually covered with increase of adsorbed liquid sulphur,which led to rapid attenuation of catalytic activity. During regeneration stage,active sites of catalyst gradually expose with evaporation of adsorbed liquid sulphur,and activities of catalyst recovered rapidly. By increasing catalyst pores and reducing heat capacity of catalyst particles,adsorption time is prolonged and regeneration time is reduce,which improve performance of sulphur recovery unit by low temperature Claus process.
