Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Redn. of NO and N2O by CO over a SiO2-supported iron oxide catalyst was studied by the transient response method, with different initial oxidn. states of the catalyst, i.e., completely reduced (Fe3O4), or oxidized (Fe2O3). The affect of CO pre-adsorption w ...
Industry requires continuously new chemical processes to convert raw materials to valuable products limiting the formation of by-products. Since a few years, an increasing interest has been given to the intensification of chemical processes. This represent ...
Nonsteady-state kinetics was used for the detn. of the reaction mechanism of a heterogeneous catalytic reaction, and the characteristic shape of the time evolution curves of the concns. at the outlet of the reactor was assocd. with rate-limiting steps. Add ...
A microchannel reactor specially designed for periodic operation and a process to deposit a catalyst, g-alumina, inside the reactor channels were developed. The hydrodynamics of the reactor was characterised. Although the flow in the microchannels is lamin ...
Adsorption to a chelating resin (Chelamine Std.) is a method for recovering heavy metals from wastewater contg. very light quantities of heavy metals (
An anisotropic structured fixed-bed divided into 2 reactor parts is a bundle reactor consisting of fiber-bundle. The fiber-bundle ordered in the flow direction are formed from filaments; the diam. of the fiber-bundle is smaller than its length and bigger t ...

The experimentally observed rise in the single pass methanol production with CO2 and H-2 (T = 200 degreesC, P = 4.3 bar) by in situ product removal over a perm-selective Nafion (R) membrane is verified by model simulations. For this purpose, software was d ...
Continuous cultures of a hybridoma cell line (Zac3) were performed in a stirred tank reactor with protein-free media. At steady state the medium was replaced by one contg. U-14C-labeled glucose. The fluxes leaving the reactor were analyzed with a scintilla ...
A continuously operated reactor was developed for the limited hydrolysis of whey protein using sol. trypsin. It consisted of a stirred tank followed by a tubular device. A stirred tank was used because it allows pH control to be achieved more easily. The t ...
A system for the independent control of ammonia and glutamine in a hollow-fiber reactor has been developed. Online anal. of the two chem. species was performed using FIA. A custom-made program has been written to fully automate the FIA, to perform measurem ...
