Abstract Scope |
Kaolinite-based clay has a fascinating microstructure with very high surface area. When bisque fired it is ideal for use as a catalyst support and for gas separation due to naturally forming porous microchannels. Recent experiments with Ni-infiltrated bisque-fired kaolinite have demonstrated that hydrogen can be produced from ethanol (ethanol steam reforming, ESR) at rates that are of high commercial interest. Additionally, the high surface area and fine pore channels lead to excellent gas separation performance. The talk will describe the processing, microstructure evolution, and mechanical integrity of kaolinite-based ceramics in the context of ESR and gas separation, where interfaces and surfaces are the key attributes. |
