“…21 The operating temperature for the dual-phase membrane appears to match the reaction temperature for the dry reforming of methane (> 700 C). Thus, the membrane offers potential for use directly in a membrane reactor packed with an adequate catalyst for carbon dioxide separation and dry reforming of methane, as illustrated in Figure 1.…”

“…Another objective of this article is to study carbon dioxide permeation through the ceramic-carbonate dual-phase membrane with the occurrence of a reaction on the downstream side. 21 To form supports of 1.5 mm in thickness, 3.0 g of the LSCF powder and PVA binder mixture was placed into a 30 mm stainless steel mold and pressed to 160 MPa for 5 min in a Carver hydraulic press. The green disks were sintered in air for 24 h at 900 C (2 C min 21 ramp rate) to produce mechanically stable, porous supports of about 20 mm in diameter and 1.5 mm in thickness, with the appropriate pore size.…”

“…First, the reaction is endothermic (DH 0 298 5 206 kJ mol 21 ) and must be carried out at high temperature, thus requiring substantial energy and capital investment to sustain a high throughput process. [6][7][8] Furthermore, the H 2 :CO ratio produced in the reaction is 3:1.…”

“…Direct partial oxidation is mildly exothermic (DH 0 298 5 236 kJ mol 21 ) and produces H 2 and CO in a ratio of 2:1. Although the H 2 :CO ratio is closer to the desired figure for methanol and Fischer-Tropsch fuel synthesis, the reaction scheme is not without drawbacks.…”

“…On the downstream (sweep side) membrane surface, the reverse of Reaction E occurs, releasing carbon dioxide and oxygen ions which transport back through the ceramic phase to the upstream membrane surface. CO 2 flux through the LSCF dual-phase membrane varied from 0.039 to 0.282 mL min 21 …”

in Wiley Online Library (wileyonlinelibrary.com) High-temperature CO 2 selective membranes offer potential for use to separate flue gas and produce a warm, pure CO 2 stream as a chemical feedstock. The coupling of separation of CO 2 by a ceramic-carbonate dual-phase membrane with dry reforming of CH 4 to produce syngas is reported. CO 2 permeation and the dry reforming reaction performance of the membrane reactor were experimentally studied with a CO 2 -N 2 mixture as the feed and CH 4 as the sweep gas passing through either an empty permeation chamber or one that was packed with a solid catalyst. CO 2 permeation flux through the membrane matches the rate of dry reforming of methane using a 10% Ni/c-alumina catalyst at temperatures above 750 C. At 850 C under the reaction conditions, the membrane reactor gives a CO 2 permeation flux of 0.17 mL min 21 cm 22, hydrogen production rate of 0.3 mL min 21 cm 22 with a H 2 to CO formation ratio of about 1, and conversion of CO 2 and CH 4 , respectively, of 88.5 and 8.1%.

This article discusses the research and development of inorganic membranes and their applications for liquid or gas separations. The general characteristics of the inorganic membranes and their historical development are introduced first followed by a brief description on the membrane morphology, preparation, and characterization. Compared to the established applications in the areas of liquid phase or particle separation, the development of inorganic membranes for gas separation is relatively new, with a more complex mechanism behind the separation and transport behavior, and therefore is the emphasis of this article. An overview of various microporous membranes including silica, zeolite, and carbon membranes and dense inorganic membranes in terms of solid oxide membranes, dual‐phase membranes, and palladium‐based metal membranes for gas separations, their relevant gas transport mechanisms, and future challenges are presented.
