Abstract: A static mixer is disclosed for a hydrogen cyanide reaction process that thoroughly mixes the reactant gases to form a ternary gas mixture that has a coefficient of variation of less than 0.1 across the diameter of the catalyst bed. The static mixer comprises tabs that are inserted through non-continuous slots in the conduit and the tabs are secured to the external wall of the conduit.

Abstract: The present invention relates to a process for producing hydrogen cyanide and more particularly, to a process for economically producing hydrogen cyanide. More particularly, the present invention relates to the controlled use of a ternary gas mixture including a methane-containing gas comprising less than 1 vol.% C2+ hydrocarbons, such as, for example, less than 5,000 mpm C2+ hydrocarbons, an ammonia-containing gas, and an oxygen-containing gas for production of hydrogen cyanide at enhanced levels of productivity and yield.
