text: The inven tion thus consists in a process for preparing hydrocyanic acid which comprises passing a stream of reactant gas comprising ammonia through a reaction zone in contact with hot electrically conductive carbon particles, maintaining a fluidized bed of said carbon particles in a dense fluidized state by the upward passage therethrough of a fluidizing gas selected from the group consisting of said reactant gas and a gas substantially inert to reaction with said carbon particles, maintaining circulation of carbon particles between said reaction zone and said fluidized bed, passing an electric current of suflicient power through the fluidized bed to maintain it at an elevated temperature suflicient to sustain reaction between the reactant gas and carbon particles to form hydrocyanic acid, separating carbon particles from product gases coming from Patented Nov. 1, 1960 said product gases.
