Abstract
Research and development on the desulfurization methods of stack discharge are advancing but there is yet to emerge a practically applicable procedure. The direct reduction method of sulfur dioxide by carbon monoxide converts sulfur dioxide into sulfur according to SO2 plus 2CO equal 1/2S2 plus 2CO2. The purpose of the present paper is to present the results of the authors' research on the possibility of direct reduction by carbon monoxide of the sulfur dioxide contained in the exhaust gas from a combustion furnace. By means of small, fixed-floor type equipment and by using a gas mixture consisting of SO2, CO, CO2 and N2, the catalytic effects (mainly of bauxite), the reaction speed and the chemical equilibrium were studied under the conditions of reaction temperatures 100 - 900C and contact time less than 0.30 seconds.
