| Popis: |
A method for the production of hydrocyanic acid by autothermic, non-catalyzed oxidation of one or several nitrogen-containing hydrocarbons or a nitrogen-containing hydrocarbon mixture, wherein the nitrogen-containing hydrocabons, an oxygen-containing gas, optionally a gas containing nitrogen oxides, optionally water, optionally ammonia, and, optionally other gas components, which behave in a substantially inert manner are placed in a flame reaction zone, are reacted in the flame reaction zone and post-reaction zone at a temperature of 1000 - 1800 °C during a reaction time of 0.03 - 0,3 s to form a cracked gas containing at least the components hydrocyanic acid, carbon oxides, hydrogen, water, ammonia, nitrogen, light hydrocarbons and, optionally, other cracked gas components, whereby the atomic C/N ratio in the reaction zones is 1 - 7 and the atomic excess air coefficient ato< >is lambdaato < 0.6, the cracked gas is cooled and separated. |
