Review Canada GIK 7P4This paper is an extensive review of the literature dealing with the class of catalytic membrane reactors which involves hydrogen permeable membranes made of palladium and palladium alloys. The fundamental factors which affect hydrogen permeability are first discussed. A classification of the many reactions which have been conducted in such reactors at both laboratory and commercial scales is then presented. The various techniques for the preparation of palladiumbased membranes are described and the literature on modeling and design of these reactors is also reviewed.Cet article passe en revue la littkrature relative B une classe de rkacteurs catalytiques z1 membranes utilisant des films de palladium ou d'alliages de palladium permtables a I'hydrogtne. On discute en premier lieu les facteurs qui affectent cette permeabilitk. On prCsente une classification des diverses rCactions et prockdes qui ont 6tC effectuCs dans de tels rtacteurs, au laboratoire et a I'kchelle commerciale. Les diverses techniques de prtparation des membranes 2 base de palladium sont dkcrites et on examine aussi la IittCrature portant sur la modClisation et la conception des rtacteurs.

In this paper, the capability of the CVD technique to produce uniform foams of different properties, with cell size ranging from ∼ 450 to ∼ 3200 μm, porosity from ∼ 70 to ∼ 98 %, and nominal thickness up to 3 mm is presented. In addition to the established application as a battery electrode material, some other potential capabilities and applications are explored.
