摘要: The hydrogenolysis of dimethyl disulfide in the presence Ni,Mo and Co,Mo bimetallic sulfide catalysts was studied at atmospheric pressure T = 160–400°C. At ≤ 200°C, undergoes S-S bond, yielding methanethiol 95–100% yield. selectivity reaction decreases with increasing residence time temperature due to undergoing condensation C-S bond yield methane hydrogen sulfide. specific activity Co,Mo/Al2O3 catalyst bonds is equal or lower than total monometallic catalysts. Ni,Mo/Al2O3 twice as active Ni/Al2O3 + Mo/Al2O3 cobalt-molybdenum catalyst.
