Porous composite particles are provided which comprise an aluminum oxide component, e.g., crystalline boehmite having a crystallite size of from about 20 to about 200 Angstroms and additive component residue, e.g., silicate, phosphate, of a crystal size growth inhibitor, intimately dispersed within the aluminum oxide component. The aluminum oxide component of the composite particles are derived from a mixture of alumina trihydrate (e.g., gibbsite) and an alumina seed component, i.e., active alumina, which are both converted to crystalline boehmite in the presence of the additive component. Also provided is a method for making the composite particles, agglomerate particles derived therefrom, and a process for hydroprocessing petroleum feedstock using the agglomerates.
L'invention concerne des particules de composite poreux constitué d'un composant oxyde d'aluminium, par exemple, de boehmite cristalline possédant une taille de cristallite de 20 Angstroms environ à 200 Angstroms environ, et d'un résidu de composant additif, par exemple, silicate, phosphate, d'un inhibiteur de croissance cristalline, intimement dispersé dans le composant oxyde d'aluminium. Le composant oxyde d'aluminium des particules de composite est dérivé d'un mélange de trihydrate d'alumine (par exemple, de gibbsite) et d'un composant germe d'alumine, c'est à dire, une alumine active, qui sont tous les deux convertis en boehmite cristalline en présence du composant additif. L'invention concerne aussi un procédé de fabrication des particules de composite, d'agglomérat de particules dérivés de ces particules, ainsi qu'un procédé permettant un hydrotraitement de matière première pétrolière au moyen de ces agglomérats.
