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.
Results concerning the coupling of the steam reforming and total oxidn. of methanol in a two-passage reactor are presented. A com. available copper-based catalyst is used for the steam reforming. For the total oxidn., a highly active cobalt oxide catalyst ...
The invention relates to an improved process for the production of powders of an inhalable medicament by crystallization from a supersaturated fluid containing said medicament, the method comprising passing along a tubular reactor(a) a segmented flow of th ...
A novel dismantlable monolithic-type electrochem. promoted catalytic reactor and "smart" sensor-catalytic reactor unit has been constructed and tested for hydrocarbon oxidn. and NO redn. by C2H4 in presence of O2. In this novel reactor, thin (.apprx.20-4 ...
The electromagnetic standing wave becomes one of the main sources of plasma nonuniformity in large area capacitively coupled rf reactors. In cylindrical reactors with a central rf connection or one-dimensional linear reactors with rf connections at both ex ...
Plasma enhanced chemical vapour deposition (PECVD) of thin films such as amorphous silicon has widespread applications especially in the field of photovoltaic solar cells and thin-film transistors for flat screen production. Industrial applications require ...
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 ...
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 ...
(Sulzer Chemtech A.-G., Switz.; Ecole Polytechnique Federale de Lausanne (EPFL)).2001
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 ...
Dihydroxyviolanthrone (I) [128-59-6] was prepd. by oxidn. of 4,4'-bibenzanthrone [116-90-5] to dioxoviolanthrone (II) [64346-54-9] with electrogenerated Mn+3+ and redn. of II to I with SO2. A decrease in current efficiency was obsd. after each cycle due to ...
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 ...
