STUDY OF ACTIVITY OF CATALYSTS SYNTHESIZED ON THE BASIS OF INDUSTRIAL WASTE IN THE REACTIONS OF REDUCING CH4/SO2 AND H2S/SO2

In the paper the results of reduction (the Claus process) of sulfur dioxide with methane and hydrogen sulfide in the presence of new red mud bentonite (RMB) of synthesized catalyst are given. Optimal conditions of the process were determined: temperature of I reactor – 8500C, volume velocity – 1000 s-1; volume ratio of initial reagents CH4/SO2=0.5–0.6, temperature of II reactor – 2500C, volume velocity – 500 s-1. Overall sulfur yield 95–97%
