Air pollution research conversion of sulfur dioxide by reaction with carbon
The reaction of sulfur dioxide with charcoal was studied in a laboratory reactor to investigate the feasibility of the process for removing SO/sub 2/ from stack gas. The main products consisted of sulfur and carbon disulfide, with some carbonyl sulfide also being formed. The initial reaction between charcoal and SO/sub 2/ to give carbon dioxide and sulfur was first order, depending only on the concentration of SO/sub 2/ and the temperature. The formation of COS appeared to be second order, and the formation of CS/sub 2/ also appeared to be second order with respect to COS. The formation of COS was hindered by the presence of SO/sub 2/ and S. Thus the conversion of SO/sub 2/ to either S or CS/sub 2/ with the liberation of either CO/sub 2/ or carbon monoxide was demonstrated.
