A process for the removal of particulate matter and sulfur oxides from waste gases is disclosed which comprises cross-current contacting of the waste gas stream with a moving bed of supported, copper-containing acceptor in a first zone, thereby accepting the sulfur oxides and filtering out the particulate matter, removing in subsequent separate zones the particulate matter and the sulfur oxides from the acceptor and, optionally, reactivating the acceptor in a subsequent zone before introducing it back into the first zone for further removal of sulfur oxides and particulate matter. An apparatus suitable for carrying out the process is also described.
