Hydrogen Production by Methane Autothermal Pyrolysis in a Moving Bed Reactor with Separate Supply of Reactants
The hydrocarbon fuel conversion in a fi ltration combustion reactor with a moving solid bed to produce
hydrogen is theoretically investigated. The process can be implemented in reactors with energy recovery with
separate supply of reagents. The entire process in the reactor can be divided into two zones: the fuel pyrolysis zone
and the hydrogen partial oxidation zone. The fuel pyrolysis occurs due to the use of heat from partial oxidation
of the fuel pyrolysis products. The target product is hydrogen, and also contains solid carbon as a product (no
CO2 emissions). The mass-energy balance of the process is calculated. The products analysis is carried out under
conditions of thermodynamic equilibrium. It has been shown that the theoretical maximum effi ciency of methane
conversion with oxygen (or air) in terms of hydrogen yields is 85%. The process combines the advantages of fuel
pyrolysis (no CO2 emissions) and fi ltration combustion (superadiabatic temperature).
