INVENTION: SULFUR DIOXIDE REDUCTION INVENTOR: W. D. DALEY ABSTRACT OF THE DISCLOSURE Sulfur dioxide is reduced to sulfur and hydrogen sulfide with a gaseous reducing agent in the presence of a catalyst by a process involving mixing a sulfur dioxide- containing gas stream with a portion of the gaseous reducing agent and passing the resulting mixture through a first reactor to effect reduction of a portion of the sulfur dioxide to hydrogen sulfide and sulfur, mixing the gas stream from the first reactor with the remaining gaseous reducing agent, and splitting the resulting mixture into two gas streams which are in parallel passed through a second and third reactor to effect reduction of sulfur dioxide to form hydro- gen sulfide and sulfur. Periodically, the flow in the first and third reactors is reversed to thereby subject these reactors to periodically alternating heat absorbing and desorbing cycles while the flow in the second reactor is always maintained in the same direction. Inlet gas temperatures to the second and third reactors are maintained within desired ranges by by-passing a portion of the sulfur dioxide-containing gas stream and reducing agent around the first reactor.
