Our Methane reformer is up and running

Methanol reforming

Summary: The metane reforming system has been successfully tested in the proof of concept phase. Two rich air-methane flames have been stabilized under controlled conditions 

There are three main methods for hydrogen production using carbon-containing fuels: steam reforming,  autothermal reforming and partial oxidation. For portable hydrogen production, most of the prototypes  fabricated and tested made use of the steam reforming process with catalyst. However, as steam reforming is  an endothermic process, a catalytic combustor is employed in parallel to supply the sufficient amount of heat to sustain the steam reforming process. This design complicates its use in portable devices for hydrogen  production. We propose in the present project to investigate hydrogen production through the partial  oxidation technique, similar to previous works [1] .

Given that partial oxidation is an exothermic reaction  (CmHn + ½mO2 mCO + ½nH2), this method avoids the integration of a combustor element and simplifies  the design and operation of the reformer, in particular for portable devices. A possible drawback of this  reformer is the deposit of soot on the walls of the channels at ultra-rich equivalence ratios, an effect that will  be carefully addressed in the present project.
