Previous work by the experimental team has successfully examined methane reforming catalysts using CO2 as the oxidant. Unfortunately, the progression to using steam as the oxidant has proved considerably more troublesome. A recent allocation of beamtime (RB1010349) was cancelled in advance of the run as initial testing highlighted material problems with the INS cells. Those issues have now been addressed and new cells designed. The new cell arrangement will be available from March 2011. This application is a re-submission of RB1010349.
