Development of a novel combined catalyst and sorbent for hydrocarbon reforming Abstract A combined catalyst and sorbent was prepared and utilized for steam reforming methane and propane in laboratory-scale systems. The am terial was prepared in the form of small spherical pellets having a layered structure such that each pellet consisted of a highly reactive lime or dolime core enclosed within a porous but strong protective shell made of alumina in which a nickel catalyst was loaded. The am terial served two functions by catalyzing the reaction of hydrocarbons with steam to produce hydrogen while simultaneously absorbing carbon dioxide formed by the reaction. The in situ er moval of CO 2 shifted the reaction equilibrium toward increased H 2 concentration and production.
