FIELD: composite materials.
SUBSTANCE: invention relates to catalyst carriers and methods for preparation thereof. Novel porous composite material particles are proposed comprising alumina component and swelled clay component finely dispersed in alumina component in amount effective to raise hydrothermal stability, pore volume, and/or pore mode in the mesopore region in composite material particles as compared to swelled clay-free material. Also proposed are composite material particles and agglomerate particles obtained therefrom as well as a method for hydroprocessing of petroleum feedstock using agglomerates as hydroprocessing catalyst carrier.
EFFECT: increased hydrothermal stability and pore volume.
