An improved process for producing HCN from CH4, NHj, and air over a platinum-alloy screen catalyst has been developed by the Freeport Sulphur Company. It involves a novel method of separating the HCN and NH3 from the gas mixture coming from the reactor. About 157 per cent of the ammonia is converted to HCN in a single pass through the converter, and only about 18 per cent is dissociated. Most of the remaining ammonia is recovered and recycled. Based on the use of recycled ammonia, the overall )deld is about 74 per cent. A flow diagram and a description of the operation for the production of liquid HCN will be found in Sec. X. <... 

Through an agreement with Freeport Sulphur Company, the Girdler Company offers the complete process and license to use it.
