“…Dense Pd [3][4][5][6][7][8], microporous silica [9][10][11][12], and carbon molecular sieve (CMS) membranes [13][14][15] have been studied for use in the MR applications for the WGS reaction. For example, Bi et al [7] used a Pt/Ce 0.6 Zr 0.4 O 2 catalyst with a hydrogen-selective Pd membrane and attained an improved performance using feeds with compositions that match those at the exit of industrial reformers.…”

“…CMS membranes, which have attracted recent attention for gas separation applications [19], have also found use in MR for the WGS reaction. Harale et al [13,14] studied a hybrid adsorbentmembrane reactor (HAMR) system to carry out the WGS reaction. They used a hydrotalcite sorbent for CO 2 adsorption and nanoporous hydrogen-selective CMS membranes.…”

[30][31][32] The work of the Tsotsis group experimentally demonstrated the sorption-enhanced membrane reactor for the low temperature WGS reaction; utility of this approach for the SMR process was investigated only through modeling of a fixed bed reactor consisting of two concentric tubes separated by a membrane with the outer (feed) shell containing SMR catalyst + CO 2 sorbent and the inner shell carrying sweep gas and permeated H 2 .…”

To meet the stringent requirements of distributed hydrogen production, combined reaction-separation approaches to the endothermic steam methane reforming process have been investigated widely as a potential means to reduce the required reaction temperature, ratio of steam to methane in the fuel (or steam to carbon ratio), and number of sequential unit operation steps. The CHAMP-SORB is a new reactor technology for distributed hydrogen production from methane that incorporates both a hydrogen-selective membrane and CO 2 adsorption into a variable volume batch operation using a four stroke cycle. Active control of the reactor volume, and hence pressure, in combination with continuous removal of both reaction products allows CHAMP-SORB to circumnavigate the equilibrium limitations of the steam-methane reforming (SMR) reaction, which otherwise limit fuel conversion, especially at temperatures below 500°C with a stoichiometric fuel mixture. In this work, we present the first demonstration of an operating CHAMP-SORB reactor, achieving SMR at temperatures as low as 400°C and at a steam to carbon ratio of 2:1. A kinetic model of the CHAMP-SORB process is developed, verified for agreement with detailed experimental measurements, and used to investigate the interactions between the reaction, permeation, and adsorption processes. Timescale analysis is introduced to explore the relationship between reactor component design dcharacteristics and the ratelimiting steps of the CHAMP-SORB. Supported by the results of kinetic simulations, the scaling analysis provides a powerful tool for rapid exploration of the operating space, including operating temperatures and hydrogen collection/utilization pressures.

“…Some systems are enhanced by adding extra features to the multifunctional reactors, as the cyclic hybrid adsorbent-membrane reactor (HAMR), which combines the functionalities of PSAR and membrane separation with reaction into a single unit for hydrogen production. 19 From all the mentioned chromatographic reactors, the SMBR is the most commonly used in the process intensification for oxygenated compounds production. The SMBR process is implemented in the well-known SMB equipment, 20 in which the columns are packed with a solid (catalyst with adsorptive properties) or a mixture of solids (a catalyst and an adsorbent).…”

A new technology, the simulated moving bed membrane reactor (PermSMBR), was presented and applied for the production of the green solvent ethyl lactate and of the biofuel 1,1-diethoxyethane. Its conception was a result of process reintensification for oxygenates production, by integrating the simulated moving bed reactor with hydrophilic membranes to enhance the water removal, leading to high process performance. For ethyl lactate synthesis, the PermSMBR technology proved to have better performance than the reactive distillation (RD) and the simulated moving bed reactor (SMBR) processes; the RD and SMBR processes require more 152 and 165% of ethanol consumption than the new technology, respectively. For the 1,1-diethoxyethane production, the PermSMBR also leads to a decrease in ethanol consumption of 69% and a productivity enhancement of 53%, when comparing with the SMBR.
