Question

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

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

Answer 1

Answer: (B)

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 into methanol $\left(C{H}_{3}OH\right)$.

The temperature of the reaction is 573 K.

$CO+H_2\stackrel{ZnO-C{r}_2{O}_3}{\to }C{H}_{3}OH$

Option D is correct.
