Solution

Separation of CO2: The above mixture passed through KOH sol. under pressure CO2 dissolves leaving behind hydrogen.

2KOH + CO → K2CO3 + H2

Separation of Co: The gaseous mixture of [CO and H2] is passed through ammonical cuprous chloride solution in order to dissolve uncombined CO.

CuCl + CO + 2H2O → CuCl.Co.2H2

Thus hydrogen gas is left over.
