Question

Which one of the following process uses water gas shift reaction?

• A. Merck's process
• B. Lane's process
• C. Permutit's process
• D. Bosch's process

Answer 1

The correct option is D Bosch's process

Bosch's process is used to produce dihydrogen Commercially and it uses Bosch's process for dihydrogen production.
$C\left(s\right)+2H_{2}O\left(g\right)\stackrel{1270K}{⟶}CO\left(g\right)+H_2\left(g\right)$

THEORY
Commercial production of hydrogen:
Bosch process:
$C\left(s\right)+2H_{2}O\left(g\right)\stackrel{1270K}{⟶}CO\left(g\right)+H_2\left(g\right)$
$CO\left(g\right)+H_2\left(g\right)$ -water gas or “syngas”
The process of producing ‘syngas’ from coal is called coal gasification
To increase the production of dihydrogen:
Water-gas shift reaction:
$H_2\left(g\right)+CO\left(g\right)+H_{2}O\left(g\right)\underset{F{e}_2{O}_3.C{r}_2{O}_3}{\overset{773K}{\to }}C{O}_2\left(g\right)+2H_2\left(g\right)$
$C{O}_2$ is dissolved in water under high pressure (20-25 atm) and the $H_2$ left undissolved is collected.
