What is the formation mechanism of the by-product COS in the CLAUS sulfur production process? Answer: The mechanism for the formation of the byproduct COS in the CLAUS sulfur production process is roughly as follows: H2S is decomposed at a certain temperature, and the amount of decomposition increases as the temperature rises: H2S → S + H2. The free H2 generated can reduce CO2: CO2 + H2 → CO + H2O. The CO produced then reacts with sulfur to form COS: CO + 1/2S2 → COS. CS2 is also partially decomposed by H2O and SO2, which leads to the formation of COS as well: CS2 + 2H2O → COS + H2S; 2CS2 + SO2 → 2COS + 3/2 S2. At the same time, hydrolysis reactions occur that reduce the amount of COS: COS + H2O → CO2 + H2S

The CO generated then reacts with sulfur to form COS: CO＋1/2S→2COS. CS2 is also partially decomposed by H2O and SO2, resulting in the formation of COS: CS2+2H2O→COS+H2S; 2CS2+SO2→2COS+3/2S2.
