Figure 5.5 Principles of dense ceramic membrane reactors (a) electrochemical pump membrane reactor (EP-MR) (b) solid oxide fuel cell membrane reactor (SOEC-MR) (c) mixed ionic-electronic conducting membrane reactor (MIEC-MR).

Abstract Dense ceramic membrane reactors are made from composite oxides, usually having perovskite or fluorite structure with appreciable mixed ionic (oxygen ion and/or proton) and electronic conductivity. They combine the oxygen or hydrogen separation process with the catalytic reactions into a single step at elevated temperatures (>700°C), leading to significantly improved yields, simplified production processes and reduced capital costs. This chapter mainly describes the principles of various types of dense ceramic membrane reactors, and the fabrication of the membranes and membrane reactors. 

This chapter will describe extensively the dense ceramic oxygen permeable membrane reactors from their principles, fabrication, and design to their applications. The prospects and critical issues of the dense...
