Abstracts:

This research consists of the numerical and experimental of chemical reactions by the flow of methane (biogas) and steam in a microchannel with catalytic walls. The numerical simulation was performed within the framework of full Navier-Stokes equations for laminar, compressible, multicomponent gas. Experiments were carried out in an annular microchannel with a rhodium catalyst on the wall. The comparison of the numerical simulation results and experimental data showed the possibility to use the kinetic scheme of methane steam reforming to simulate the biogas steam reforming without considering the additional reaction of carbon dioxide conversion with methane. The temperature regimes with high conversion levels of methane and biogas were found. It is shown that, the complete conversion of methane and biogas in the microchannel can be occurred at length of several centimeters at the constricted conditions. This demonstrates the feasibility of the compact hydrogen production systems based on microchannel technology.
