Adsorption-enhanced steam–methane reforming

“…permeate purge) gases, have limited the usefulness of the membrane reactor systems. Nevertheless, the bene"ts of the membrane systems have been demonstrated though a wide number of experimental reaction studies, examples of which include the dehydrogenation of ethane (Tsotsis, Champagnie, Vasileiadis, Zraka & Minet, 1992), cyclohexane (Sun & Khang, 1988), ethylbenzene (Wu, Gerdes, Pszczolowski, Bhave & Liu, 1990), and acetylene (Itoh, Xu & Sathe, 1993), CO production via the water}gas shift reaction (Uemiya, Sato, Ando & Kikuchi, 1991), and steam}methane reforming (Adris, Lim & Grace, 1994, 1997.…”

Process intensification aspects for steam methane reforming: An overview

“…Among these the membrane thickness is the most important construction parameter. 66 Significant efforts in the development of membrane reactors considering these aspects for SMR were undertaken by Adris et al 67,68 These authors have carried out both experimental and numerical investigations on the use of hydrogen selective membranes to overcome the thermodynamic equilibrium barrier in bubbling fluidized bed membrane steam reformer (BFBMSR). An improved circulating fast fluidized bed membrane reformer (CFFBMR) 69 further overcomes the limitations of the BFBMSR specifically in terms of flexibility, fluid dynamic limitations, and ability for continuous catalyst regeneration.…”
