1. A process of making hydrogen, the process comprising:

  • flowing a first reactant comprising methane through a first flow path;

    flowing a second reactant comprising air through a second flow path;

    reacting air and methane to produce an exhaust and an amount of heat;

    heating the first reactant and the second reactant with a first portion of the amount of heat;

    flowing the exhaust through a third flow path;

    flowing a third reactant through a fourth flow path, wherein the third reactant comprises water and methane;

    heating the third reactant with a second portion of the amount of heat;

    reacting the third reactant to produce a product comprising hydrogen and carbon monoxide;

    flowing the product through a fifth flow path; and

    transferring heat from the product to the third reactant in the fourth flow path, wherein;

    the first flow path, the second flow path, the third flow path, the fourth flow path, and the fifth flow path are coaxial about a longitudinal axis,the third flow path is in fluid communication with the first flow path and with the second flow path, andthe fourth flow path is in fluid communication with the fifth flow path.
