Resumen:
Methane is the main source of hydrogen worldwide. Under
certain circumstances, dry reforming (DRM) is an appealing option [1]. One
drawback is the high endothermicity of this reaction. Thus, the co-feeding of
oxygen becomes attractive from the standpoint of the overall energy balance of
the process. In any case, however, the product stream must be carefully treated
in several steps to obtain very pure hydrogen (< 10 ppm CO) for fuel cell
use. This is why the use of a membrane reactor to obtain ultrapure hydrogen in
a single vessel becomes so appealing. In this work we report the results
obtained when the dry reforming of methane (DRM) was conducted in the presence
of oxygen in the membrane reactor. The catalysts used were Rh and Ru supported
on lanthana, which are known to be active, stable catalysts for the dry
reforming of methane in membrane reactors [2,3].
