Question

Which of the following catalyst is used in the conversion of water gas and hydrogen to methyl alcohol?

• A. $MnO$
• B. Raney $Ni$
• C. $Fe$
• D. $ZnO-C{r}_2{O}_3$

Answer 1

The correct option is D $ZnO-C{r}_2{O}_3$

The industrial method of preparation of methanol includes catalytic reduction of carbon monoxide. For this purpose, water gas is used.
Water gas is an equimolar mixture of $CO$ and $H_2.$ A mixture of zinc oxide and chromium oxide $(ZnO-C{r}_2{O}_3)$. converts water gas in methanol $\left(C{H}_{3}OH\right)$.
The reaction for methanol preparation is as follow:
​
Hence correct option is (d).
