Abstract: A catalyst composition useful in the hydroprocessing of a sulfur- and metal-containing hydrocarbon feedstock comprises 1.0-5.0 weight percent of an oxide of nickel or cobalt and 10.0-25.0 weight percent of an oxide of molybdenum, all supported on a porous alumina support in such a manner that the molybdenum gradient of the catalyst has a value of less than 6.0 and 15-30% of the nickel or cobalt contained in the catalyst is in an acid extractable form. The catalyst is further characterized by having a total surface area of 150-210 m 2 /g, a total pore volume of 0.50-0.75 cc/g, and a pore size distribution such that pores having diameters of less than 100A constitute less than 25.0%, pores having diameters of 100-160A constitute 70.0-85.0% and pores having diameters of greater than 250A constitute 1.0-15.0% of the total pore volume of the catalyst. A method for the hydroprocessing of a sulfur- and metal-containing hydrocarbon feedstock comprises contacting the feedstock with the abovedescribed catalyst and hydrogen in a manner such that the catalyst is maintained at isothermal conditions and is exposed to a uniform quality of feed. The method is particularly effective in achieving desired levels of hydrodesulfurization in vacuum residua feedstocks.

Abstract: Process for the preparation of polyalkoxylated aromatic compounds from aromatic compounds bearing at least one halogen atom and at least one hydroxyl group. More precisely, the invention is a process for the preparation of polyalkoxylated aromatic compounds, characterised in that the following stages are carried out: 1 - An aromatic compounds bearing at least one halogen atom and at least one hydroxyl group is reacted with an alkali metal or alkaline-earth metal alcoholate in the presence of a catalyst which is copper and/or a copper compound and of a cocatalyst chosen from organic carbonates, mixed organometallic carbonates, carbon dioxide or compounds capable of forming carbon dioxide. 2 - The O-alkylation of the hydroxyl group(s) of the product obtained previously after alkoxylation is carried out by direct addition to the organic reaction mixture of an alkylating agent chosen from lower alkyl halides, dialkyl sulphates and dialkyl carbonates. The invention thus makes it possible to carry out the alkoxylation reaction and the O-alkylation reaction in succession.

Abstract: Un procédé de préparaton d'un matériau polymère poreux consiste à chauffer un mélange comprenant un polyfluorure de vinylidène et un système de solvant composé intitialement d'une première composante qui est un solvant latent de polyfluorure de vinylidène et d'une seconde composante qui n'est pas un solvant de polyfluorure de vinylidène, de sorte que, à une température élevée, le polyfluorure de vinylidène se dissout dans le système de solvant pour produire une solution optiquement claire. La solution est alors rapidement refroidie de sorte qu'une séparation en phase liquide-liquide non équilibrée ait lieu pour produire une phase continue riche en polymère et une phase continue pauvre en polymère, les deux phases étant mélangées sous forme d'une matrice bicontinue à large interphase. Les processus de refroidissement est poursuivi jusqu'à ce que la phase riche en polymère se solidifie. La phase pauvre en polymère est enlevée du matériau polymère solide. Un matériau poreux ainsi produit est caractérisé par une texture filamenteuse ou analogue à une dentelle composée d'une multiplicité de brins de polymère (1) reliés entre eux en différents endroits (2) espacés le long de chaque brin.

Abstract: Dispositif de commande (102) de diode laser utilisant un microcontrôleur programmé (162) pour commander de manière précise le procédé d'allumage et de sélection du point de fonctionnement de la diode laser (100). La diode laser (100) comprend une facette frontale (100) pour transmettre la lumière, et une facette arrière (114) pour surveiller la puissance optique émise par la diode laser. Une fois la facette arrière (114) de la diode laser (100) étalonnée, le dispositif de commande peut surveiller de façon précise les caractéristiques de fonctionnement de la diode laser, et peut choisir le meilleur courant de point de fonctionnement en fonction des caractéristiques de fonctionnement de la diode laser (100). Au cours de l'étalonnage de la diode laser (100), le dispositif de commande (102) peut vérifier la linéarité de la puissance optique émise par la diode en fonction du courant de commande, et peut ainsi détecter des défaillances de la diode laser (100). Dans une liaison optique en duplex total, le dispositif de commande (102) de la présente invention empêche les diodes laser de générer de la lumière à leur pleine intensité normale jusqu'à ce que l'intégrité de la liaison ait été établie, évitant ainsi que la lumière émanant de la diode ne blesse accidentellement les yeux de l'utilisateur. De plus, le dispositif de commande (102) peut utiliser la liaison en duplex total pour établir des courants de commande de point de fonctionnement inférieurs à ceux qui devraient normalement être utilisés, ce qui prolonge de façon significative la durée de vie des diodes laser (100). Les caractéristiques de fonctionnement d'une diode laser changent avec le temps de manière déterminée, ce qui permet au dispositif de commande (102) de prédire le moment où le laser va subir une défaillance.
