Sulfur dioxide reduction process utilizing catalysts with spinel structure

Patent ·
OSTI ID:6077367
; ;

A catalytic process for the reduction to elemental sulfur of the sulfur dioxide contained in gas streams using a reducing gas such as hydrogen, or preferably carbon monoxide, in a reactor charged with a material represented by the general formula M/sup II/M/sub 2//sup III/O/sub 4/ crystallized in the spinel stucture wherein M/sup II/ is a divalent metal and M/sup III/ is a trivalent metal from the first transition period of the Periodic Table of the Elements, or derivatives of the materials of the above formula resulting from pretreatment with hydrogen or, preferably carbon monoxide, and/or exposure to the sulfur dioxide-containing gas stream.
