Der volle Inhalt der QuelleSteam reforming of bio-fuels in catalytic membrane reactors can be used to produce pure hydrogen, which in turn can feed H2/O2 fuel cells for on-board applications in the automotive Industry. Hydrogen can be extracted and purified by permeation across a metallic membrane made of palladium alloy. The use of such membranes pose some treats : (i) the rate of permeation and life time increasing ; (ii) costs reduction (thin membranes developpment) ; (iii) high selectivity (no CO). For these reasons, there is a need to separately probe surface (chemi-dissociation) and bulk (H diffusion transport) contributions to the overall permeation rate. Pneumato-chemical impedance spectroscopy (PIS) which originally was developed for analyzing the dynamics of hydrogen sorption in metal hydride powders has been used for analyzing permeation. An experimental set-up (Sieverts type) has been constructed to collect raw thermodynamic and kinetic data and obtain experimental transfer functions. A model has been developped to obtain microscopic rate parameters associated with individual reaction steps (surface resistance and diffusion coefficient). Results are consistent with those obtained in stationary conditions of flow. In transient conditions of flow, shifts in rate-determining steps have been evidenced. The methodology has been used to characterize different alloys of palladium (palladium-silver and palladium-copper) and characterize a prototype permeator

Der volle Inhalt der QuelleThis work focuses on the challenge of hydrogen purification from gas mixtures (containing CO2 and CH4) under pressure in natural reservoirs. The firts research part is dedicated to developing a new experimental breakthrough curve measurement device. This required substantial calibration of the setup's various components (mass flow meters, analyzer, pressure controller, dead volume, etc.). Additionally, like many laboratory setups, it has a dead volume comparable in magnitude to the reactor volume. Consequently, it was necessary to study the influence of this dead volume on the shape of the breakthrough curve.Pressurized gas mixture flow tests over an inert material (glass beads) were also conducted to evaluate the axial dispersion coefficient of the compounds in the pressurized fluid. Finally, dynamic adsorption experiments were performed on gas mixtures (CO2, CH4, H2) at different compositions, pressures, and a constant temperature. The modeling and numerical simulation of the experimental breakthrough curves are based on the "Linear Driving Force" transfer model in the porous medium. In this model, the adsorption capacities of the mixture components are accounted for using the "Ideal Adsorbed Solution Theory" model, previously validated by studying the isotherms of pure components and mixtures. The tested adsorbents include activated carbon and polystyrene beads. A comprehensive characterization of these adsorbents determined their specific surface areas, pore size distributions, and real and apparent densities. Finally, the adsorption capacities of these adsorbents under the conditions of use were evaluated through adsorption isotherm studies of the compounds, either individually or in mixtures. This analysis validated the "SIPS" model for predicting pure component isotherms and the "Ideal Adsorbed Solution Theory" model for gas mixtures, as previously mentioned

Der volle Inhalt der QuellePalladium-silver alloys are used in the industry for the purification of hydrogen. State-of-the-art materials still require optimization (i) to increase permeation flows ; (ii) to maintain performances on the long-term ; (iii) to reduce investment costs (development of thin membranes). To achieve these goals, it is necessary to measure in situ surface (H₂ dissociative chemisorption) and bulk (diffusion transport of atomic H) kinetic contributions. The kinetics of chemical (gas-phase) and electrochemical (electrolyte) hydrogen insertion have been compared. Electrochemical and chemical impedance diagrams have been obtained from “potential step” and from “pressure step” experiments. Rate constants of individual steps have been measured. Then, the insertion of gaseous hydrogen into a metallic membrane of known surface state (texture and roughness factor) and known volume microstructure (grain size distribution) has been investigated. Values of surface resistance and hydrogen diffusion coefficient have been measured with temperature. By measuring the impedance of membranes of different thicknesses, it has been shown that the surface step is rate-determining. Then, the surface roughness of a membrane has been increased by electrochemical deposition of palladium black. A membrane showing a reduced surface resistance has been prepared and a diffusion impedance diagram has been obtained for the first time for a gas phase experiment

Der volle Inhalt der QuelleThis work focused on the interest of using a zeolite composite membrane (CHA SSZ-13) accessible on a commercial scale through the membrane technology of gas and vapor permeation. The applicability of this separation technology has mainly focused on the recovery of methane, propane and isobutene from fluxes produced at industrial scales by sustainable processes. The development of an experimental lab scale pilot for gas and vapor permeation data measurements is detailed. Based on experimental permeation measurements carried out with the zeolite membrane of the study, a first case of practical application was to simulate the separation performance of a hybrid process associating a zeolite membrane module with a cryogenic condensation from an industrial specification for the recovery of isobutene. The hybrid process studied is always more efficient than the only cryogenic condensation process taken as reference in terms of purity of the condensed product obtained and energy consumption. A chart was generated to locate the simulated separation performance based on the desired isobutene recovery objective. A second theoretical case of propane recovery from nitrogen purging vents with hybrid membrane cryogenic separation process was studied. This study presented a chart of the membrane separation performance of propane over nitrogen according to data from the open literature. The most nitrogen- and propane-selective membrane (CHA SSZ-13 and PEBAX 2533 respectively) was then selected and used in order to simulate hybrid processes where separation performances were compared to a baseline cryogenic standalone process. For low propane contents in the nitrogen feed mixture, it was found that the most efficient process (energy need and quality of the condensed product) involved a PEBAX 2533 polymer membrane module with a vacuum system for the permeate

Der volle Inhalt der QuelleThe present work focuses on the study of a nanofiltration step to purify solutions containing lactate and glucose. From previous results, it was concluded that, whilst good separation was expected from results obtained with single solute solutions, the NF selectivity achieved with mixed solutions was finally very poor. On the other hand, it was demonstrated that the presence of a charged solute can change significantly the retention of either neutral or charged ones. The objective of this experimental study is to investigate to what extend the addition of an electrolyte can improve the selectivity of lactate / glucose separation by nanofiltration. Experimental results were used to get the variation of the observed retentions vs. The permeation flux and to evaluate the separation efficiency from the separation factor. In presence of NaCl, both glucose and lactate retentions slightly decrease and remains very close except at low permeation fluxes where the addition of NaCl has more effect on lactate retention than on glucose one. On the contrary, whilst the addition of Na2SO4 has no influence on glucose retention, a strong effect was pointed out on the lactate retention, especially for high electrolyte concentrations for which negative retentions were obtained at low permeation fluxes. Then, the separation improvement by adding salt is much more important in presence of Na2SO4 compared to NaCl. A maximum separation factor of 1. 9 was obtained with Na2SO4 at 0. 25 M adding to the glucose / lactate solution whereas the separation was impossible without the addition of salt

Der volle Inhalt der QuelleThe aim of this work is the development of micro- and mesoporous membranes of new generation for gas separation, with special insight into tubular and hollow fibre geometries. After a review of the state of the art, we present the techniques of preparation and synthesis of the membranes. In a third section, a detailed study is presented, focusing on the influence of the desorption conditions on the pure gas permeance and gas mixture separation in MFI tubular membranes. Gas desorption prior to any test appears to be a crucial step not only to obtain reliable gas permeance data, but also to also to improve the separation performance of a membrane in practical applications. In a fourth section, we present, for the first time, the synthesis of nanocomposite MFI/alumina hollow fibres, where the zeolite material crystallizes in the alumina support pores instead offorming a surface film. This architecture offers not only more mechanical stability, but also a better separation performance at high temperature. In a fifth section, this work presents, also for the first time, the characterization of nanocomposite MCM-41(‘LUS’)/alumina tubular membranes, with a mean pore size about 3 nm. A last section provides complementary results of permeance and gas separation

Der volle Inhalt der QuelleThe elimination of carbon dioxide has become a worldwide challenge to minimize its impact on global warming. Capture using physical adsorption is viable as long as the right adsorbent is found. CO2 capture from flue gases poses a number of problems in terms of low CO2 concentration (below 20%), low total pressure, and the eventual presence of water. This study focuses on the impact of water vapour during CO2 adsorption on different porous materials. An experimental device has been developed to assess the impact of water vapour during CO2 adsorption: both the heats of adsorption and the breakthrough curves were obtained. The uptakes of CO2 at 0.2 bar have been studied in porous materials after having been pre-equilibrated under different relative humidity's (3 and 40%). The enthalpies allow a better understanding of the phenomena involved. Several MOFs, like HKUST-1(Cu), UiO-66(Zr), MIL-100(Fe), MIL-101(Cr), MIL-127(Fe) have been compared to a zeolite NaX and an activated carbon Takeda-5A.Three different behaviours are shown: - Where water has a negative impact on CO2 adsorption. This can be due to poisoning or the poor stability of the materials like HKUST-1. - Where water seems to have little effect on CO2 adsorption like case of UiO66. - Where water has a positive effect on CO2 uptake. Slight improvement for MIL-101(Cr) and remarkable enhancement of CO2 uptake through pre-adsorption of water vapor has been highlighted here in two cases: the mesoporous MIL-100(Fe) and the bifunctional MIL-127(Fe).This work is part of the European project FP7 Macademia "MOFs as Adsorbents and Catalysts: Discovery and Engineering of Materials for Industrial Applications"
