Abstract

Separation of Sulfur dioxide by a new environmentally friendly method through its reduction to sulfur was investigated. Nickel catalyst was synthesized on two bases of alumina and activated carbon, using a wet impregnation method. Both catalyst series in two combinations of different percentages of nickel metal were synthesized, characterized and their performance in the reactor test in terms of conversion rate and selectivity for the desired product were compared. The effect of reaction temperature was investigated in the range of 550-800 ° C. At low temperatures, activated carbon-nickel catalysts have better performance than the Alumina-nickel catalyst. Effect of molar feed ratio of SO2/CH4= 3-1 was studied and stoichiometric feed ratio showed the best performance. Also, investigation of reaction time for catalysts showed a good long-term stability for SO2 reduction with methane in 8 hours. Mean activation energy based on Arrhenius model was determined 0. 32 and 0. 20 for alumina-nickel and CA-nickel catalysts, Respectively.
