Both chemical looping processes and oxygen permeable ceramic membranes require gas-solid surface reaction to occur in order to function; the two approaches have much in common at a fundamental level. Both approaches, through either dynamic operation in the case of looping or membrane operation, allow a degree of process intensification through simultaneous reaction and separation. Here the use of chemical looping and oxygen permeable ceramic membranes for hydrogen production is reviewed. Hydrogen production from water with various reducing gases is covered, as is synthesis gas production from hydrocarbons with various oxidants (this requiring 10 further hydrogen separation from the synthesis gas). The two approaches are compared and contrasted.

“…The POM reaction in CMRs is an old concept; however, the commercialization of this process has not yet been realized and the development of an MIEC membrane with long-term stability is one of the main challenges. In the past several years, most of the work in this area has focused on developing novel membrane materials 6,[8][9][10]41,43,44,[92][93][94][95] (see Table S1, Supporting Informationw) and designing membrane reactors with new configurations. 7,62,63,71,74,75,80,[96][97][98][99] These studies have been discussed in previous sections.…”

Catalytic membrane reactors which carry out separation and reaction in a single unit are expected to be a promising approach to achieve green and sustainable chemistry with less energy consumption and lower pollution. This article presents a review of the recent progress of dense ceramic catalytic membranes and membrane reactors, and their potential applications in energy and environmental areas. A basic knowledge of catalytic membranes and membrane reactors is first introduced briefly, followed by a short discussion on the membrane materials including their structures, composition and strategies for material development. The configuration of catalytic membranes, the design of membrane reaction processes and the high temperature sealing are also discussed. The performance of catalytic membrane reactors for energy and environmental applications are summarized and typical catalytic membrane reaction processes are presented and discussed. Finally, current challenges and difficulties related to the industrialization of dense ceramic membrane reactors are addressed and possible future research is also outlined.

The other group of the membrane materials explored is composites comprising an oxygen ion-conducting phase and an electron-conducting phase .…”

A Novel Energy-Efficient Process for Production of Nitrogen from Air via a Reaction-Driven Membrane Reactor

Gaseous nitrogen has a wide variety of applications in industry. Currently, nitrogen is produced by energyintensive cryogenic fractional distillation of liquefied air, pressure swing adsorption (PSA), and membranes. In this paper, a novel process was proposed and experimentally verified for production of nitrogen. In this process, oxygen in air is extracted through a dense oxygen−permeable membrane, which is then reacted with methane. By optimizing the air and methane flow rate, the process can produce nearly pure nitrogen as well as a syngas (a mixture of CO and H 2 ). At 800 °C, the reactor produced nitrogen at a rate of 9.2 mL cm −2 •min −1 with purity over 99%, and methane was reformed to syngas with CH 4 throughput conversion over 90%, H 2 selectivity of 92%, and CO selectivity of 92%. The syngas can be burned to generate heat or used as intermediate chemicals for production of liquid fuels and hydrogen. Since the membrane reactor is driven by the energy released by the reaction and does not consume high grade energy electricity, it has a much higher overall energy efficiency than the current industrial nitrogen separation processes.
