Abstract: To develop the laser-catalytic approach of olefins production from C2-C3 alkanes we designed a reactor where the zone of homogeneous endothermic pyrolysis of C2-C3 alkanes (gas zone) is surrounded by the zone of catalyst (porous zone) where methane and hydrogen are oxidized with energy release. This energy goes into the zone of gaseous pyrolysis by means of thermo conductivity of products of deep oxidation: CO2 and H2 O. The energy of CO2 laser that is effectively absorbed by the mixture components is introduced into the same zone to increase the rate of methyl radical generation. Using ANSYS FLUENT software package we developed numerical model of such laser-catalytic reactor, where the transient 3D flow of gas mixture in gas and porous media is reproduced. We used specially defined coefficients of diffusivity to model the multi-component gas flow and Zimont approach to introduce the radiation into gas. The aim of simulation is to verify whether the higher diffusivity of hydrogen compared to the other components of the mixture can influence the selectivity of the pyrolysis.
