Abstract: Processes and systems for the production of hydrogen cyanide via the Andrussow process are described. A reaction zone, wherein oxygen, ammonia, and methane can be allowed to react in the presence of a catalyst comprising platinum to provide hydrogen cyanide. A desulfurization zone, wherein a feed stream comprising sulfur and at least one of the oxygen, the ammonia, and the methane can be contacted with a desulfurization material to produce a sulfur- reduced feed stream that is provided to the reaction zone. In an example, the desulfurization material includes zinc oxide.

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.
