In Hydrofining catalytic desulphurisation process for sweetening of petroleum products, use of hydrogen_________________?
Correct answer: C. Both A. and B.
- A. Enhances the desulphurisation process
- B. Minimises coke formation
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Hydrogen reacts with sulphur compounds over the hydrofining catalyst, increasing their conversion to removable hydrogen sulphide. It also hydrogenates coke-forming unsaturated compounds, so both desulphurisation and coke suppression are improved.
