Abstract
The water required for the production of ammonia and carbon monoxide by the catalytic decomposition of hydrocyanic acid present in gases which also contain hydrogen is produced in situ at elevated temperature by introducing a gas containing oxygen. If air is employed for this purpose it is advantageous to combine the process with the manufacture of hydrocyanic acid, the gases after absorption of ammonia and addition of hydrocarbons or carbonaceous material and hydrogen being blown through an electric arc. When the gases containing hydrocyanic acid do not contain sufficient hydrogen for the production of the necessary amount of water, hydrogen must be added before the gases are introduced into the chamber containing the usual catalysts such as ferric oxide, chrome iron or a mixture of ferric and aluminium oxides.
