Modeling of a Catalytic Flat Plate Fuel Reformer for Hydrogen-Rich Reformate Fuel Available to Purchase

In this study, using a two-dimensional computational fluid dynamics (CFD) model with co-current flow arrangement, steam reforming of methane coupled with methane catalytic combustion in a catalytic plate reactor is investigated. The two-dimensional approach makes the model more realistic by increasing its capability to capture the effect of design parameters such as catalyst thickness, reaction rates, inlet temperature and velocity, and channel height, and eliminates the uncertainties introduced by heat and mass transfer coefficients used in one-dimensional models. In our work, we simulate the entire flat plate reformer electro-kinetics and carry out parametric studies related to design matrices that can provide guidance for the practical implementation of such design. The operating conditions are chosen in such a way which makes possible a good comparison of the catalytic plate reactor and catalytic combustion analysis with the conventional steam reformer. The CFD results obtained in this study is very helpful to understand the optimized design parameters to build a first generation prototype.
