Abstract

This work experimentally evaluates a novel non-premixed opposed-flow reactor for reforming gaseous fuels. Our reactor is like the canonical opposed-flow reactor commonly used in flame studies but has a catalyst-coated metal mesh located between the air inlet and fuel inlet. Experiments were conducted to evaluate both temperature profile and species profiles of the rector with methane as fuel at different catalytic mesh location. We operated the reactor using wash coat supported platinum on the metal mesh as the active material. A CHEMKIN diffusion opposed-flow model with modified GRI-30 mechanism was created based on reactor boundary condition. This model provided a preliminary estimate of local equivalence ratio based on species diffusion. Our results show that the reactor can convert methane to reforming products and mesh stoichiometry plays a critical role in optimizing the reforming products. Moreover, the data experimentally confirm that the catalytic mesh serves like a flame sheet in an opposed flame reactor by completely reacting the oxygen without crossover.
