Catalysis in membrane reformers: a high-performance catalytic system for hydrogen production from methane

Combined oxidation and reforming of methane to produce pure H2 in a membrane reactor

“…For this reaction, we and others have reported that the CH 4 conversion can be greatly improved by removing the hydrogen formed with a stable and highly selective dense Pd-Ag membrane [3][4][5]. Ferreira-Aparicio et al used a Ni-catalyst in a membrane reactor and showed similar results [6]. However, one problem lies in the high-energy requirement of this reaction.…”

“…However, in the case of a membrane reactor the situation is different because H 2 is being extracted from the reaction side (retentate). Ferreira-Aparicio et al [6] employed a highly selective Pd film (12-35 m) supported on porous stainless steel and several Nibased catalysts in a membrane reactor for the dry reforming reaction. They found that a CO 2 excess in the feed stream with respect to the stoichiometric ratio establishes more favorable conditions for the membrane reactor operation with lower carbon deposition.…”

Thermodynamic analysis and performance of a 1kW bioethanol processor for a PEMFC operation

“…The applications of membrane reactors to produce CO-free hydrogen streams are limited because palladium, the active phase, is so expensive [20,21] and also the costs associated with pressure control system required for their operation [22].…”

Development of compact and efficient hydrogen production module with membrane on catalyst

“…Membrane reactors have been studied intensively as excellent apparatus for the production of hydrogen from hydrocarbon and alcohols (Tosti, 2010;Ferreira-Aparicio et al, 2005). In general, a membrane reactor consists of catalysts for the SMR and metallic membranes which separate the produced hydrogen.…”
