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.
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 ...
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 ...
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 ...
A new reactor concept for catalyzed three-phase reactions based on the use of woven fibrous materials for bubble columns is suggested. In comparison to conventional multistage bubble columns, the trays are made from woven fibrous catalytic layers. The hydr ...
A new industrial process for the electrolytic regeneration Mn2(SO4)3 is presented in which: a slurry of MnSO4/Mn2(SO4)3 in 55% H2SO4 was used as a carrier, the electrolyte is purified with an optimum mode before electrogeneration, and a new industrial elec ...
New critical experiments in the framework of an IAEA Coordinated Research Program on `Validation of Safety Related Reactor Physics Calculations for Low-Enriched HTR's' are planned at the PSI PROTEUS facility. The experiments are designed to supplement the ...
Exptl. investigations of the thermal bulk polymn. of styrene (I) in pilot plants of different sizes were done. Each pilot plant consisted of a tubular recycle reactor connected in series with a tubular reactor, both completely filled with Sulzer motionless ...
The performance of steady-state flow ultrafiltration membrane reactors can be considerably increased by improving their hydrodynamic characteristics. A tubule recycle membrane reactor was designed and constructed. This type of reactor approximates plug flo ...
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 ...
The highly efficient Semliki Forest virus (SFV) system has been applied to express several recombinant 7TM receptors and ligand-gated ion channels. High affinity binding and functional coupling to G proteins were obtained for the receptors. The ligand-gate ...
