During the first year a pair of laboratory reactors has been designed, constructed and commissioned which are capable of studying the relevant methane reactions (i.e., partial oxidation and steam reforming) at temperatures up to 1450K. A chemical analysis train has been developed which provides the qualitative and quantitative measurement of CH4, CO2, H2, O2, N2, and CO. Preliminary results indicate that while methane is essentially unreactive toward homogeneous attack by steam (i.e., in the absence of any catalyst) oxygen readily activates its dissociation. Three modeling approaches have been identified for possible use in describing the proposed system one of which is used to describe complete methane combustion as a test reaction.
