Which of the following reactions increases the production of dihydrogen from synthesis gas?
Options
- ACH 4 g + H 2 O g → Ni 1270   K CO g + 3 H 2 g
- BC s + H 2 O g ⟶ 1270   K CO g + H 2 g
- CCO g + H 2 O g → Catalyst   673   K CO 2 g + H 2 g
- DC 2 H 6 + 2 H 2 O → Ni 1270   K 2 CO + 5 H 2 ,
Correct answer
C. CO g + H 2 O g → Catalyst   673   K CO 2 g + H 2 g
Step-by-step solution
The process of producing syn gas or synthesis gas from coal is called 'coal gasification'. C s Coal + H 2 O g Steam → Ni 1270   K CO g + H 2 g ⏟ Synthesis gas The production of hydrogen can be increased by reacting carbon monoxide of the syn gas with steam in the presence of iron chromate as a catalyst at 673   K . CO g + H 2 O g ⟶ FeCrO 4 ,   673   K CO 2 g + H 2 g CO 2 is removed by scrubbing with a solution of sodium arsenite.
