Dkt. No. 46-DV-2062 ABSTRACT OF THE DISCLOSURE A process and system for simultaneously removing from a gaseous mixture, sulfur oxides by means of a solid sulfur oxide acceptor on a porous carrier, nitrogen oxides by means of ammonia gas and particulate matter by means of filtration and for the regeneration of loaded solid sulfur oxide acceptor. Finely-divided solid sulfur oxide acceptor is entrained in a gaseous mixture to deplete sulfur oxides from the gaseous mixture, the finely-divided solid sulfur oxide acceptor being dispersed on a porous carrier material having a particle size up to about 200 microns. In the process, the gaseous mixture is optionally pre-filtered to remove particulate matter and thereafter finely-divided solid sulfur oxide acceptor is injected into the gaseous mixture to form an entrained bed. Ammonia gas is also injected into the exhaust gas stream. A filter separates spent solid sorbent and particulate matter from clean gas. A classifier is used to separate mixtures of spent sorbent from particulate matter. A regenerator receives spent sorbents for regeneration and means are provided for passing regenerated finely-divided solid sorbent from the regenerator to the entrained bed reactor. A preferred sorbent is copper oxide on porous alumina carrier.
