ABSTRACT:
An ammonia converter is disclosed. The converter can alter the conversion of ammonia by controlling the reaction temperature of the exothermic reaction along the length of the reactor to parallel the equilibrium curve for the desired product. The converter can comprise a shell101and internal catalyst tubes109. The feed gas stream enters the reactor, flows through the shell101, and is heated by indirect heat exchange with the catalyst tubes109. The catalyst tubes109comprise reactive zones122having catalyst and reaction limited zones124that can comprise inert devices that function to both separate the reactive zones, increase heat transfer area, and reduce the temperature of the reaction mixture as the effluent passes through the catalyst tube109.
