Membranas Inorgânicas e reatores catalíticos
(1997)
norganic membranes and catalytic reactors. Membrane reactors are reviewed with emphasis in their applications in catalysis field. The basic principles of these systems are presented as well as a historical development. The ...
Performance of the catalytic membrane reactors of different pore size with palladium as catalytic phase in hydrogenation and oxidation reactions
(2018)
The catalytic membrane reactors (CMR) were prepared using a commercial Hollow Fiber Membrane of corundum of 4 and 1400 nm and impregnated palladium. The tests performed were phenol hydrogenation, hydrogen peroxide generation ...
Development of catalytic membranes over PdAu selective films for hydrogen production through the dry reforming of methane
(Elsevier B.V., 2018-07)
PdAu composite membranes were applied in the preparation of catalytic membranes for hydrogen production. The APTES surface modification of PdAu membranes synthesized by sequential electroless deposition was carried out. ...
An environmentally friendly triphasic catalytic system: Mn(salen) occluded in membranes based on PDMS/PVA
(ELSEVIER SCIENCE BV, 2010)
The commercially available Jacobsen catalyst, Mn(salen), was occluded in hybrid polymeric membranes based on poly(dimethylsiloxane) (PDMS) and poly(vinyl alcohol) (PVA). The obtained systems were characterized by UV-vis ...
Catalytic palladium-based and iron-based membrane reactors: Novel strategies of synthesis
(American Chemical Society, 2019-11)
Several procedures were employed in the preparation of different Pd- and Fe-based catalytic membrane reactors (CMRs) via the normal wet impregnation method, reverse filtration of a microemulsion, sputtering method, and the ...
Chromium(VI) reduction in aqueous medium by means of catalytic membrane reactors
(ELSEVIER LTD, 2016-06-01)
A novel method for catalytic reduction of chromium(VI) to chromium(III) in model and real water is proposed in this work. Hydrogen was used as a reducer. Three different catalytic membrane reactors were prepared and employed ...
Durable ethanol steam reforming in a catalytic membrane reactor at moderate temperature over cobalt hydrotalcite
