Abstract
La présente invention concerne un catalyseur comprenant un support extrudé essentiellement à base d'alumine, et constitué d'une pluralité d'agglomérats juxtaposés et se présentant en partie sous la forme d'empilements de feuillets et en partie sous la forme d'aiguilles, et comprenant éventuellement au moins un métal catalytique ou un composé de métal catalytique de groupe VIB, et/ou éventuellement au moins un métal catalytique ou un composé de métal catalytique du groupe VIII. Elle concerne également son utilisation dans un réacteur à lit fixe, pour l'hydroraffinage et l'hydroconversion de charges hydrocarbonées.
