Abstract
PURPOSE: To selectively decompose and remove NH3 without decomposing hydrocyanic acid by bringing a formed gas contg. hydrocyanic acid and NH3 into contact with a catalyst based on iron and/or iron oxide at an elevated temp.
CONSTITUTION: In synthesis of hydrocyanic acid using NH3 as one of raw materials, a formed as contg. hydrocyanic acid and NH3 is brought into contact with a catalyst baed on iron and/or iron ixide at an elevated temp. above 500, esp. 700W 1100°C to selectively decompose the NH3. This catalyst contains 0.1W50, esp. 1W15 wt% (as iron oxide) of the iron and/or iron ixide. since it is required for the catalyst to be heat resistant, carrier such as alumina or silica, pref. r-alumina is pref. used. The above gas to be treated is undesirable to containg O2 or water
