Abstract (en)

[origin: CN101269824A] The invention relates to a method for preparing hydrogen cyanide according to andrussow process, which is carried out by reacting methane gas, ammonia gas and oxygen-containing gas at rising temperature on catalyst. Oxygen has a volume proportion (O<2>/(O<2>+N<2>) of 0.2 to 1.0 corresponding to total volume of nitrogen and oxygen, and the reaction is carried out by adopting mixture of incombustible reactant gas.
