  • Process for producing hydrogen cyanide
    Patent number: 4128622
    Abstract: Hydrogen cyanide is commercially produced by reacting in the vapor phase ammonia, air, and a hydrocarbon gas, e.g., natural gas, in the presence of a platinum group metal catalyst. The operation of this process to obtain optimum hydrogen cyanide production is accomplished by determining HCN production at various natural gas feed rates, i.e., varying the air/natural gas ratio, while maintaining a constant air/ammonia ratio. Once the production peak is located, the natural gas feed is maintained at the corresponding rate.
