A catalyst and sorbent is disclosed which comprises pellets with an
absorbent core and a protective shell with a catalyst in the shell. Such
material is especially well suited for steam reforming of hydrocarbons to
produce hydrogen since a reforming catalyst can be incorporated in the
shell and a sorbent for the by-product carbon dioxide can be used for the
core. It is also well suited for producing hydrogen from carbon monoxide
by means of the water gas shift reaction. The shell can be made
sufficiently strong and durable for moving bed applications as well as
fixed bed applications.
