| 英文摘要 | Cuo/al2o3 sorbent-catalyst has been studied extensively for so2 removal from flue gases of stationary sources. in these studies the so2-adsorbed cuo/al2o3 is treated by reducing reagents such as h-2 to yield concentrated so2, which is further converted in a separate catalytic reactor to valuable products, such as elemental sulfur. this work reports a novel technique, which combines the so2 removal, h-2 regeneration of the sorbent-catalyst, and elemental sulfur recovery into one reactor using a cuo/al2o3 sorbent-catalyst simply by recycling the effluent gases back to the reactor during h-2 regeneration. this combined process can be operated isothermally at 400 degrees c with 83% yield to elemental sulfur. the catalyst for the elemental sulfur formation is likely to be cus formed in the h-2 regeneration. most of the cu species regenerated from the h-2 regeneration is cu-0, which converts to cuo and cuso4 during the so2 removal stage. |
