Chattez avec Graph Search
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.
A gravimetric app. contg. catalyst particles (H2SO4 on silicate) is used to det. the ethylene [74-85-1] absorption rate during the prepn. of vinyl acetate [108-05-4] from ethylene and AcOH. The influence of the absorption process on the overall reaction at ...
Oscillation of the reaction rate, leading to strong, irregular oscillation of the conversion in dependence on the time, and sudden conversion changes occurred in certain temp. and concn. regions in the exptl. study of the catalytic hydrogenation of C2H4 wi ...

H-ZSM-5 zeolite has been shown to be an active catalyst for the synthesis of polyoxymethylene dimethyl ethers (OME). However, we demonstrated – by passivation of the zeolite's external surface – that the reaction rate is limited due to severe internal diff ...
We develop a model to investigate the time evolution of the mean location and variance of a random walker subject to Poisson-distributed collisions at constant rate. The collisions are instantaneous velocity changes where a new value of velocity is generat ...
