Question

Water gas is mixed with steam and the mixture is passed over heated Fe2O3 in presence of Cr2O3. The mixture when passed in water dissolves CO2 and dihydrogen left undissolved is collected. This method of preparation of hydrogen gas is known as (A) Bosch process (B) Lane process (C) Kellner process (D) Hall process

Tardigrade Admin · Accepted Answer

For the commercial preparation of dihydrogen, Bosch process is used.
In Bosch's process, water gas (i.e.

CO + H_{2}

) is mixed with twice of its volume of steam in presence of catalysts

F e_{2} O_{3}

and

C r_{2} O_{3}

or

T h O_{2}

where

C r_{2} O_{3}

acts as promoter. It gives the products

C O_{2}

and

H_{2}

. Now,

C O_{2}

is dissolved in water & removed leaving

H_{2}

behind which is undissolved.
