Abstract
An ammonia converter system and method are disclosed. The reactor 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 reactorcan comprise a shelland internal catalyst tubes. The feed gas stream enters the reactor, flows through the shell, and is heated by indirect heat exchange with the catalyst tubes. The catalyst tubescomprise reactive zoneshaving catalyst and reaction limited zonesthat 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 tube
