Question

methane + nh3 with alumina product asked?

Answer 1

Hydrogen Cyanide (HCN)

Answer 2

The reaction of methane ($\text{CH}_4$) with ammonia ($\text{NH}_3$) in the presence of alumina ($\text{Al}_2\text{O}_3$) as a catalyst at high temperatures is a significant industrial process for the synthesis of hydrogen cyanide (HCN). This process is often referred to as the BMA process (Bauscher-Degussa process).

The balanced chemical equation for the reaction is:

$\text{CH}_4 (g) + \text{NH}_3 (g) \xrightarrow{\text{Al}_2\text{O}_3, \Delta} \text{HCN} (g) + 3\text{H}_2 (g)$

The main product is hydrogen cyanide.

Methane reacts with ammonia over an alumina catalyst at high temperatures to produce hydrogen cyanide and hydrogen gas.
