| 英文摘要 | in this study, the regeneration conditions of mn-fe-zn-o supported upon gamma-al2o3 sorbents for high-temperature desulfarization of fuel gases were investigated. nln-fe-zn/gamma-al2o3 sorbents with mn/fe/zn molar ratio of 2:1:0.2, amfz0.2, were prepared. desulfurization and regeneration were carried out in a quartz fixed-bed reactor of 10-mm diameter. sulfidation tests were performed at 650 degreesc using the gas mixture containing (mol) 0.3%h2s-11.62%h-2-19.34%co-6.85%co2-61.84%n-2 at sv=3000 h(-1). sulfur capacity of the fresh sorbent was about 5.3 gs/100 gsorbent. regeneration parameters including temperature, concentration of oxygen, space velocity and steam content have been considered in order to obtain suitable regeneration conditions. the regeneration was performed at the following parameters-pressure: atmosphere, temperature: 600-750 degreesc, space velocity: 2000-3000 h(-1) and gas composition (vol.%): 2-8 o-2, 4-10 h2o with n-2 balance. typical properties of the sorbents before and after regeneration were characterized using xrd, sem, bet and icp methods. the most suitable regeneration conditions were obtained including 700 degreesc of regeneration temperature, 6.0% of oxygen content and 8.0% of steam in the gas stream.
