| In a heated tubular reactor with a total reaction volume of 1.4 l, a reactant stream of 0.5 kg/h of methanol and 0.95 kg/h of hydrogen sulphide was fed in at a pressure of 9 bar. The reaction chamber was filled, in the first, upper reaction zone (60% of the total reaction volume), with the catalyst identical . In the second, lower reaction zone (40% of the total reaction volume), the catalystwas disposed. At a wall temperature of 320¡ã C., a reaction temperature between 320 and 380¡ã C. within the first reaction zone and between 320 and 325¡ã C. within the second reaction zone, a conversion of methanol of 99% was established at the reactor outlet. The selectivity for methyl mercaptan was 95.5%, the yield of methyl mercaptan 94.5% |
