    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.
