Poster summary

The existing hydrogen production technologies are associated with a number of hardship and disadvantages. The process of methane catalytic pyrolysis permits one to obtain the hydrogen along with nanostructured carbon at significantly lower temperatures then thermal pyrolysis of methane. The efficiency of the catalytic decomposition of methane-hydrogen mixture over the NiO-CuO/Al2O3 catalyst was studied using the reactor with McBain balances. The kinetic model based on the dissociative adsorption of methane was used for the mathematical modeling. The defined kinetic constants for this model provide an appropriate fitting of the experimental points. In order to optimize the process parameters for catalytic decomposition of methane–hydrogen mixture, the mathematical modelling was carried out using the non-stationary mathematical model.
