PROCESS AND APPARATUS FOR CONTINUOUSLY PREPARING HYDROGEN SULFIDE

摘要

The invention relates to a method and a device for producing hydrogen sulfide H2S by the reaction on a fixed catalyst of a reactant mixture containing gaseous sulfur and hydrogen. The reactant mixture is reacted in a reactor (1) at an absolute pressure from 0.5 bar to 10 bar, a temperature from 300°C to 450°C, and an excess of sulfur. The sulfur excess corresponds to a ratio of excess sulfur to produced H2S of 0.2 kg to 3 kg sulfur per kg of produced H2S.
