Renewable Hydrogen

The optimum design, modeling and simulation of a fixed bed multi-tube reformer for the renewable hydrogen production are carried out in the present paper. The analogies between plug flow model and a fixed bed reactor are used as design patterns. The steam reformer is designed to produce enough hydrogen to feed a 200kW fuel cell system (>2.19molH/s) and considering 85% of fuel utilization in the cell electrodes. The reactor prototype is optimized and then analyzed using a multiphysics and axisymmetric model, implemented on FEMLABM(R) where the differential mass balance by convection-diffusion and the energy balance for convection-conduction are solved. The temperature profile is controlled to maximize hydrogen production. The catalyst bed internal profiles and the effect of temperature on ethanol conversion and carbon monoxide production are discussed as well.

Ethanol Reactions

In this study, a mechanism containing ethanol reactions is employed and the effects of exhaust gas fuel reforming on operation parameters such as ignition timing, burn duration, temperature, pressure and NOx emission are studied in which a homogeneous mixture is assumed. The results show that hydrogen in the form of reformed gas helps in lowering the intake temperature required for stable HCCI operation. It is concluded that the addition of hydrogen advances the start of combustion in the cylinder. This is a result of the lowering of the minimum intake temperature required for auto-ignition to occur during the compression stroke, resulting in advanced combustion for the same intake temperatures. The obtained results from the model are compared with the experimental data published in the literature and the comparison showed a reasonable compatibility.
