Question

(A) In the industrial production of hydrogen from water gas,the mixture of $CO$ and $H_2$ is passed over a catalyst (usually $Fe_2O_3$ and $Cr_2O_3$)

Vedclass · Accepted Answer

$CO$ is oxidized to $CO_2$ with steam in the presence of a catalyst,and then $CO_2$ is absorbed in an alkali.

Vedclass · Answer

(A) In the industrial production of hydrogen from water gas,the mixture of $CO$ and $H_2$ is passed over a catalyst (usually $Fe_2O_3$ and $Cr_2O_3$) at $673 \ K$ with steam. This is known as the water-gas shift reaction:$CO(g) + H_2O(g) \xrightarrow{673 \ K, 	ext{catalyst}} CO_2(g) + H_2(g)$After the reaction,$CO_2$ is removed by scrubbing the mixture with an alkali solution (like $NaOH$ or $K_2CO_3$),which absorbs $CO_2$ to form carbonates,leaving behind pure $H_2$.

Which of the following statements is true regarding the industrial production of hydrogen gas from water gas $(CO + H_2)$?
