    摘要： Methods, systems, and apparatus for mass flow are provided. The apparatus can include a housing, an inlet disposed at a first end of the housing, and an outlet disposed at a second end of the housing. The housing can include a first section and a second section. The second section can have at least one tapered sidewall that slopes away from an inner surface of the first section toward the outlet. The apparatus can also include a divider disposed at least partially within the first and second sections of the housing. The divider can have at least one tapered surface disposed proximate the at least one tapered sidewall of the second section. An edge of the divider can be located between the outlet and a point within the second section where the cross-sectional area of the second section is about three times or less a cross-sectional area of the outlet.

    摘要： 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 reactor 100 can comprise a shell 101 and internal catalyst tubes 109. The feed gas stream enters the reactor, flows through the shell 101, and is heated by indirect heat exchange with the catalyst tubes 109. The catalyst tubes 109 comprise reactive zones 122 having catalyst and reaction limited zones 124 that 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 109.
