Consider the industrial processes involving coal gasification and the water-gas shift reaction. Whic — Hydrogen Chemistry Question

💡 Solution & Explanation

Syngas ($CO + H_2$) is made by passing steam over hot coke at $1270\text{ K}$. The hydrogen yield is increased via the water-gas shift reaction, where $CO$ reacts with steam at $673\text{ K}$ over $FeCrO_4$ catalyst to form $CO_2$ and $H_2$. The resulting $CO_2$ is removed by scrubbing with a sodium arsenite solution.
