FIELD: chemical technology.
SUBSTANCE: invention relates to a method for producing peptised aluminum oxide, which involves mixing aluminum oxide in the form of boehmite and acid in a ratio of about 0.16 to about 0.65 mol of acid/mol of aluminum oxide in an aqueous acidic solution for a sufficient period of time and using a mixer with sufficient energy and intensity to form essentially free-flowing solid particles of peptised aluminum oxide with a solid content of about 45 to about 65 wt %, measured as the total volatile content at a temperature of 954°C (1750°F) for 1 hour, and the amount of aqueous acidic solution is less than the pore volume of aluminum oxide in terms of initial moisture capacity. The invention also relates to a method for producing a fluidized catalyst.
EFFECT: faster catalyst production and lower costs due to high solids concentration and less water requiring evaporation.
