Methane reforming operated in fluidized bed reactors is modelled and simulated for four different chemical processes: Steam Methane Reforming (SMR) process and the both non-commercially available Sorption-Enhanced Steam Methane Reforming (SE-SMR) process and Chemical Looping Reforming process for non-autothermal (naCLR) as well as autothermal (aCLR) operation. These processes are operated at relevant operating conditions. The results from the reforming simulations are used as input in a Pressure Swing Adsorption model, where the hydrogen is further purified to about 99.99 % and delivered at 2500 kPa (25 bar) of pressure and 25 °C. The energy consumption for hydrogen production on a mole basis is calculated for each chemical process with and without heat recuperation, with heat recuperation referring in this context to the utilization of the thermal energy available from the cooling of certain fluid streams to power other parts of the process.
