Title (EN) ZEOLITE/SIC COMPOSITES AND THE USE THEREOF AS A CATALYST
(FR) COMPOSITES ZEOLITHE/SiC ET LEUR UTILISATION EN CATALYSE
Abstract: front page image
(EN)The invention relates to a composite comprising a zeolite (such as zeolite ZSM-5, zeolite-$g(b) and silicalite) which is deposited on a rigid support. The inventive composite is characterised in that said rigid support comprises a silicon carbide (SiC) having a BET specific surface area which is greater than 5 m2/g. Preferably, the support is a $g(b)-SiC foam having a specific surface area of between 10 and 500 m2/g. Said composite can be used as a catalyst or as a catalyst support for chemical reactions in a gaseous or liquid medium, for example, for the cracking, acylation, alkylation or isomerisation of hydrocarbons.
(FR)L'invention concerne urrcomposite formé d'une zéolithe (telle que la zéolithe ZSM−­5, la zéolithe−&bgr;et la silicalite) déposée sur un support rigide, caractérisé en ce que ledit support rigide est constitué d'un carbure de silicium (SiC) ayant une surface spécifique BET supérieure à 5 m2/g. De façon préférentielle, le support est une mousse de &bgr;−SiC avec une surface spécifique comprise entre 10 et 500 m2/g. Ce composite peut être utilisé comme catalyseur ou support de catalyseur pour des réactions chimiques en milieu gazeux ou liquide, par exemple le craquage, l'acylation, l'alkylation ou l'isomérisation des hydrocarbures.
