Title:
水熱的に安定な高い細孔容積を有する酸化アルミニウム/膨潤性粘土組成物およびこれの製造および使用方法
Document Type and Number:
Japanese Patent JP4754144
Kind Code:
B2
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.
