Question

Water gas is mixed with steam and the mixture is passed over heated $Fe_2O_3$ in presence of $Cr_2O_3$. The mixture when passed in water dissolves $CO_2$ and dihydrogen left undissolved is collected. This method of preparation of hydrogen gas is known as

Prashant Kotian · Accepted Answer

Correct answer: A. Water gas (1 : 1 volume ratio of CO and hydrogen) is mixed with steam and passed over 2 3 Fe O catalyst with promotor 2 3 Cr O etc. at 440 550 C 2 2 2 2 Fe O Cr O 2 3 2 3 440 550 C CO H H O CO 2H -> This is Bosch process.
