Fossil hydrogen with reduced CO2 emission:modeling thermocatalytic decomposition of methane in afluidized bed of carbon particlesMuradov, N. et al. International Journal c?f Hydrogen Energy, 2005, 30,(10), 1149 1158.Thermocatalytic decomposition (TCD) of methane is an environmentallyattractive approach to the production of hydrogen with reducedCO2 emissions. The perspectives of large-scale hydrogen productionvia TCD of natural gas (NG) are discussed in this paper. The processinvolves a fluidised bed reactor-regenerator system with carbon catalystparticles circulating between the apparatuses in a fluidised state.Modelling and scaling-up of a fluidised bed reactor (FBR) for TCD ofNG is presented in this paper. In particular, two mathematical models,one for the bubbling fluidised bed and the other for the turbulentfluidised bed, were developed and implemented into a computer codeto predict the FBR performance. These models capture most of thechemistry and physics occurring within the FBR. Model predictionscompared favourably with the experimental data on methanedecomposition over carbon catalyst particles.
