摘要
A process for sepg. oxides of sulphur from gas mixts. contg. them and contg. also oxygen, e.g. furnace gases, consisting of contacting the gas mixt. with a sorption solid contg. an active constituent, incorporates oxidn. of a part of the active constituent after regeneration and before sorption. The process may be carried out using several sorption beds in a cycle of sorption and regeneration. One of the beds is used for sorption while other beds are being regenerated. The oxidn. may be carried out using the treated gas from the sorption beds. About 35% of the active matl. should be oxidised. The process is partic. effective in cyclic sorption operations using copper, vanadium or a mixt. of vanadium and potassium, or an inert support e.g. alumina. The process achieves a greater recovery of sulphur oxides from gas mixts. contg. them than existing processes.
