| 英文摘要 | Cuo/al2o3 is capable of removing so2 and nox from flue gas simultaneously at around 400 degrees c. after the so, removal, the so2-adsorbed cuo/al2o3 needs to be treated to regenerate its so2 removal capacity and to recover the removed sulfur. this paper reports recent research on direct formation of elementary sulfur during h-2-regeneration of the so2-adsorbed cuo/al2o3 through recycling of the regeneration tail gas. in such a way, the so2 removal, the sorbent-catalyst's regeneration and elementary sulfur recovery can be carried out in a single reactor. the operating parameters studied include the amounts of h-2 fed into the reactor, h-2 feed strategy and o-2 treatment of the h-2-regenerated cuo/al2o3. an intermittent h, feeding mode is found to give a higher elementary sulfur yield (91%), less residual sulfur-compounds in the system after the regeneration, and higher so, capacity in the subsequent so2 removal process. an o-2 treatment after the h-2-regeneration improves the elementary sulfur yield further and results in a number of other advantages.
