Question

Cryogenic process is coupled with which type of separating technique of deuterium?

(a) Dual temperature exchange

(b) Distillation

(c) Electrolysis

(d) Hydrogen distillation

I have been asked this question during an online exam.

The doubt is from Inorganic Chemical in section Inorganic Chemical Industries of Chemical Technology

Answer 1

The correct answer is (d) Hydrogen distillation

For explanation I would say: The cryogenic or low -temperature process must be coupled with a synthesis gas plant to extract the deuterium and effectively use the hydrogen for chemical synthesis or rocket propellant fuel.
