Processes for the production of hydrogen cyanide from the reaction of methane with ammonia at temperatures above about 800.degree. C. where the reactor contains a matrix bed of heat resistant materials. The product stream produced within the reactor is preferably routed in a countercurrent fashion to the feed stream entering the reactor to preheat the feed stream and to lower the exit temperature of the product stream. Reactors capable of being used to practice such processes are also provided by the invention.

[ What is claimed is:] [1.] A process for producing hydrogen cyanide, comprising:(a) directing a gaseous feed stream comprising methane and ammonia to an inlet of a matrix bed reactor, wherein the concentration of the methane and ammonia is at least 50% by volume of the feed stream;(b) directing the feed stream into a plenum within said reactor;(c) directing the feed stream from the plenum through an inside portion of a plurality of feeding tubes, the feeding tubes having an entrance end and an exit end, the feeding tubes extending through a gas impermeable barrier such that the entrance end of the feeding tubes is located within the plenum and the exit end of the feeding tubes is positioned either within a matrix bed of heat resistant materials that is located within the reactor or within a void located adjacent to the matrix bed within the reactor at a position remote from the gas impermeable barrier;(d) maintaining a reaction temperature of at least 800.degree. C. within at least a portion of the reactor;(e) reacting the methane with the ammonia to form a product gas stream comprising hydrogen cyanide; and(f) exiting the product gas stream from the reactor by passing the product gas around the outside portion of the feeding tubes and through a reactor outlet, whereby the feed stream is recuperatively preheated within the feeding tubes by the thermal energy possessed by the product gas stream.
