SPHEROIDAL PARTICLES OF ALUMINUM OXIDE WITH IMPROVED MECHANICAL STRENGTH, HAVING AVERAGE DIAMETER OF MACROPORES, BETWEEN 0,05 AND 30 mcm Russian patent published in 2020 - IPC C01F7/02 C01F7/24 C01F7/26 C01F7/44 C01B3/40 B01J21/04 B01J23/40 B01J32/00 B01J35/08 B01J35/10 B82Y40/00

Abstract RU 2716435 C2

FIELD: chemistry.

SUBSTANCE: invention can be used in obtaining a catalyst support used in catalytic reforming. Spheroidal alumina particles have a BET specific surface area, is 150–300 m²/g, an average particle diameter of 1.2–3 mm, the dispersion of particle diameters, defined as the standard deviation of not greater than 0.1. Said particles have total pore volume, measured by mercury porosimetry making between 0.50–0.85 ml/g, degree of macroporosity in one particle smaller than 30. Spread of macropore diameters, expressed through ratio of diameters D90/D50, does not exceed 8.

EFFECT: invention increases strength of aluminum oxide particles.
