Abstract
Porous composite particles are provided which comprise an aluminum oxide component, e.g., crystalline boehmite, and a swellable clay component, e.g., synthetic hectorite, intimately dispersed within the aluminum oxide component at an amount effective to increase the hydrothermal stability, pore volume, and/or the mesopore pore mode of the composite particles relative to the absence of the swellable clay. Also provided is a method for making the composite particles, agglomerate particles derived therefrom, and a process for hydroprocessing petroleum feedstock using the agglomerates to support a hydroprocessing catalyst.
