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.

Abstract: A process for the production of hydrogen cyanide comprises feeding a reaction mixture feed to a plurality of primary reactors each comprising a catalyst bed comprising platinum, wherein the reaction mixture feed comprises gaseous ammonia, methane, and oxygen gas, determining whether a percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below a threshold, identifying one or more suboptimal reactors amongst the plurality of primary reactors when the percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below the threshold, and supplementally feeding the reaction mixture feed to one or more supplementary reactors when the one or more suboptimal reactors are identified, wherein each of the one or more supplementary reactors comprises a catalyst bed comprising platinum. The supplemental feeding can be performed in place of the feeding of the reaction mixture feed to the one or more suboptimal reactors or in addition to the feeding of the reaction mixture feed to the one or more suboptimal reactors. The overall process is sufficient to maintain an overall measured hydrogen cyanide production rate amongst the one or more supplementary reactors and the primary reactors that is within a desired overall hydrogen cyanide production rate range.

Abstract: A method and a system for recovering hydrogen from a process for making hydrogen cyanide are described herein. In the method, hydrogen is recovered from a gaseous waste stream of an Andrussow process. The method comprises the following steps: (a) adjusting a reaction mixture comprising methane, ammonia and oxygen to provide the reaction mixture with sufficient oxygen to generate a gaseous waste stream that has at least 40% hydrogen after removal of ammonia and recovery of hydrogen cyanide; and(b) removing components from the gaseous waste stream to generate recovered hydrogen.

Abstract: The following example is a method treating a cyclohexylhydroperoxide (CHHP) hydrogenation catalyst. A reactor is provided that is filled with a partially deactivated hydrogenation catalyst from a CHHP hydrogenation process. A regeneration stream is then fed into the reactor, wherein the regeneration stream is a portion of the product mixture from the CHHP hydrogenation process. The partially deactivated hydrogenation catalyst is then contacted with the regeneration stream and finally the used regeneration stream is recovered from the reactor.
