On-board hydrogen generation from hydrocarbon fuels, such as methanol, natural gas, gasoline and diesel, etc., will be technically feasible in the near future for fuel cell powered vehicles. Among all the fuel processing methods, steam reforming is considered as the most widely used method of hydrogen reforming for the lower reactive temperature, pressure and higher hydrogen ratio in reformate. A laminate micro-channel catalytic reactor was designed for the purpose of hydrogen generation from hydrocarbons. The depth of the reaction channel is 0.5 mm, and the length and width are 50 mm and 40 mm, respectively. The same geometry is designed for the heating channels. A metal sheet is placed between reacting and heating channels to separate them. Piling up alternately the two channels is to buildup the laminate microchannel reactor. Numerical simulation has been conducted in one reactive unit, i.e., one reacting channel and one heating channel. The reactant is the solution of methanol and water mixing with a certain ratio. And the reaction heat is provided by hot air flow with a temperature of 600K. A 2D steady model of the reforming reactive processes was developed and solved numerically. The ratio of water and methanol is set to be at 1.3. The conversion rate of methanol was nearly 100% at the outlet of reactor, while the volume ratio of hydrogen is 51.4% with the selectivity of CO2 reaches 49.2%. Detail results showed that the 50 mm long reacting channel could be divided into four different regimes along with the reacting course. In the first regime (0-5mm), methanol in the reactants is almost completely converted and CO is mainly generated in the third one (15-20mm), while reactions in the other two regimes are indiscoverable. The reasons leading to such phenomena are clarified in this paper.

Production Of Hydrogen

Numerical modeling of methane-steam reforming is performed in a mini/microchannel with heat input through Nickel-deposited channel walls. The low-Mach number, variable density Navier-Stokes equations together with multicomponent reactions are solved using a parallel numerical framework. Methane-steam reforming is modeled by three reduced-order reactions occurring on the reactor walls. The surface reactions in the presence of Nickel catalyst are modeled as Neumann boundary conditions to the governing equations. Effects of the total heat input, heat flux profile, and inlet methane-steam molar concentration on production of hydrogen are investigated in detail.
