“…Other relevant examples are the use of H 2 permselective membranes in GTL technology to enhance the gasoline yields [6,7] and the integration of H 2 membranes with PEM fuel cells to eliminate poisoning by CO and CO 2 [8]. Pd-based thin films are usually utilized in such a type of H 2 permselective membranes, because ideally (e.g.…”

Dedicated to the friend Helmut Knözinger on in the occasion of his 75 th birthday for the seminal contribution to the advancement of fundamental knowledge on catalysis. AbstractThe use of co-deposition instead of sequential deposition during the preparation of Pd-Ag thin films by electroless plating deposition leads to two different nanostructures, e.g. a dendritic nanostructure or a more compact and dense film, allowing to analyze the role of this parameter, at equal membrane composition, on the performances. In pure H2 the permeability to hydrogen of the second type of thin films is 3-4 times higher, but the presence of CO2 in the feed changes considerably the performances. The results are tentatively interpreted on the basis of a non-permanent in situ modification of the characteristics of the Pd-Ag thin films, with creation of strains and microholes particularly enhanced for the nanostructure present in the sample prepared by co-deposition. These strains and microholes are suggested to derive from the combined effect of CO2 (with creation of subsurface O and/or C) and of hydrogen diffusion through the thin film, which induces lattice expansion and stress on the nanograins. When the flux of H2 stops, there is a relatively rapid restoring of the initial situation. Scanning electron microscopy (SEM) characterization after the tests in the presence of CO2 indicates the presence of desintering consistently with above indications and the creation of crack like voids.

High-temperature Fischer-Tropsch (HTFT) process aims to produce lighter cuts such as gasoline and diesel. For many years there have been studies and improvements on HTFT process to make the existing reactors more efficient. Recent studies proposed new configurations such as dual-type membrane reactor and coupling configurations reactor, which improved the performances of this process. This achievement persuades us to update the existing knowledge about the available reactors for HTFT process. In this article, features and performances overview of two classes of reactors are reviewed. The first class consists of the reactors which are based on older studies, and the second one includes recent studies which are called product intensifier reactors. Finally, it is shown that the product intensifier reactors have higher CO conversions and lower selectivity of undesired by-products which results in higher production yield of gasoline. Furthermore, the place of product intensifier reactor among common reactors with regard to the influence of the process parameters on the product distribution has been estimated.

“…Prof. Rahimpour's group proposed the application of fluidized bed membrane reactors for different reaction systems. In particular, an example of fluidized bed applied to Fisher-Tropsch reaction system can be found in Rahimpour (2009b). In this work Pd-based membranes are inserted in a fluidized bed in a two reactors plant as indicated in Figure 18.…”
