Jose VALVERDE considère que la responsabilité des intellectuels dans la vie de la Cité est très importante mais il ne croit pas qu’ils ont un rôle moteur dans celle-ci. Dans le meilleur des cas ils peuvent espérer montrer la réalité mais ils ne la produisent pas.

VENT DE TEMPÊTE - THÉÂTRE DU NORD-OUEST

L'âme humaine n'existe que par sa mise en scène. La vie humaine n'existe que par sa mise en abîme. L'honneur humain n'existe que par sa mise en cause. Scène-abîme-cause même combat, le seul l'unique combat pour le dépassement de la survie et pour la vraie vie dans le paradis mental des acteurs qui se trémoussent sur scène pour nous faire pleurer ou nous faire rire. Défendons le théâtre corps et âmes, becs et griffes, contre vents et marées.

Determination of Intraparticle Diffusivities Using a Single Pellet String Fixed Bed and a Shallow-Bed Diffusion Cell

A theoretical model was developed to describe the response of the system that includes the resistance to mass transfer inside the particle and the effect of the electric field (Nernst-Planck approximation). Equilibria were described using a homogeneous model based on the mass action law in which nonideal behavior for both the solution and the solid phase was taken into account. Simulations were performed to analyze the effect of the model parameters on the response curves. The values of intraparticle diffusivities of Na + and K + were obtained by nonlinear regression. Both the regression and the parameters were highly meaningful from the statistical point of view. A simple dimensionless relationship that relates diffusivity (through the Schmidt number) to different physical properties of solvents (namely, viscosity, dipolar moment, and density) and resin swelling was found.

Electrochemical activation of Au nanoparticles for the selective partial oxidation of methanol

Journal of Catalysis, 2014

ABSTRACT An electrochemical catalyst based on Au nanoparticles dispersed in an yttria-stabilized ... more ABSTRACT An electrochemical catalyst based on Au nanoparticles dispersed in an yttria-stabilized zirconia (YSZ) matrix was prepared by reactive cosputtering of zirconium–yttrium and Au targets on a K-βAl2O3 solid electrolyte. The Au/YSZ catalyst film deposited on K-βAl2O3 was found to be active in the partial oxidation of methanol with a high selectivity toward methyl formate. This configuration allowed to electrochemically promote a highly dispersed Au catalyst by K+ ions and allowed to decrease the amount of metal used in the solid electrolyte cell. The back-spillover of K+ ions sharply increased the H2 and HCOOCH3 production rates up to more than 9 and 5 times, respectively. A number of experiments confirmed that the observed electro-promotional effect did not depend on the rate of K+ supply nor on the operation mode (galvanostatic or potentiostatic) and only depended on the promoter coverage (total applied charge). The stability of the Au–YSZ catalyst film under the explored conditions was also verified.

Deactivation kinetics of toluene alkylation with methanol over magnesium-modified ZSM-5

A kinetic model taking into account both the deactivation of the main and the secondary reactions and the influence of the intracrystalline diffusion has been developed. The best fit of the experimental data has been obtained assuming that gaseous hydrocarbons, formed mainly by ethylene,

Electrochemical reforming of ethylene glycol. Influence of the operation parameters, simulation and its optimization

Fuel Processing Technology, 2014

ABSTRACT A compact pure hydrogen production process was developed based on the electrochemical re... more ABSTRACT A compact pure hydrogen production process was developed based on the electrochemical reforming of ethylene glycol-water mixtures by using a low temperature proton exchange membrane (PEM) electrolysis cell. A bimetallic 40% Pt-20% Ru carbon based anode and a 20% Pt carbon based cathode were used for the PEM electrochemical reforming experiments. The main operation parameters (applied current, feed stream flow rate, concentration and temperature) were experimentally studied and optimized to enhance the hydrogen production rate. As a result and based on the experimental data, a complete integrated process was proposed and simulated by Aspen HYSYS software. Considering the energy requirements of the different units of the process, an energetic evaluation of the whole system was carried out by integrating the experimental current-potential data. Thus, material and energy balances of the overall process have been calculated for each of the possible current-working conditions. Hence, the optimal operating conditions, which led to the highest energetic efficiency of the system (57%) were attained at a current density of 0.08 A/cm(2), leading to a total energy consumption of 17.14 kwh kg(H2)(-1). The analysis presented in this paper also offers a better understanding of the characteristics of a PEM electrochemical plant for hydrogen production.

Effect of vibration on the stability of a gas-fluidized bed of fine powder

Physical Review E, 2001

The powder is uniformly fluidized by an adjustable gas flow that enables us to control the average solid volume fraction straight phi(0). The fluidized bed is then subjected to a vertical oscillatory motion of controlled amplitude and frequency. The response of the fluidized bed depends essentially on the value of straight phi(0). For straight phi(0)&amp;amp;gt;0.28 the fluidized bed is in a weak solidlike regime, it has a mechanical strength, and particles are static. In this regime vibration causes compaction of the loosely packed bed. For straight phi(0)&amp;amp;lt;0.28 the mechanical strength vanishes and stresses are carried by interstitial gas and collisions. In this fluidlike regime the fluidized bed displays a diffusive dynamics and particles aggregate due to the strong interparticle van der Waals forces. When vibration is applied the powder expands due to the partial disruption of aggregates. However at a critical value of the vibration amplitude A=A(c) either surface (sloshing) or flow (bubbling) instabilities develop. The nucleation of gas bubbles has been correlated to the saturation in particle diffusivity measured elsewhere. The size of the bubbles increases as A is further increased above A(c) and as the vibration frequency is reduced. Moreover, as it should be expected from the predictions of hydrodynamic models, A(c) is independent of cohesivity for particles of the same size and density.

Correlation between bulk stresses and interparticle contact forces in fine powders

This additive is well known for its ability to control interparticle adhesion force. Parallel measurements using an atomic force microscope have been carried out on the adhesion force between two individual grains as a function of a controlled previous load force. The effect of the additive on the tensile strength and adhesion force is analyzed. We have found a good correlation between bulk stresses and adhesion forces between individual particles. This correlation is compatible with the existence of a subnetwork of force chains.
