Abstract

ESSENTIALLY SPHERICAL PARTICLES ARE DISCLOSED OF AT LEAST 98.5% ALUMINA HAVING A SURFACE AREA LESS THAN ABOUT 1 M2/G AN ATTRITION RESISTANCE OF LESS THAN ABOUT 0.3 WEIGHT PERCENT/HOUR IN AN AIR JET ATTRITION TEST, A PARTICLE SIZE OF ABOUT 30 TO ABOUT 110 MICRONS, A TAP DENSITY OF ABOUT 1.3 TO ABOUT 1.9 G/CC, AND SUFFICIENT POROSITY TO HOLD CATALYTIC METALS IN CONVENTIONAL CATALYTIC AMOUNTS. THE ALUMINA PARTICLES ARE ESPECIALLY SUITED FOR USE AS FLUID BED CATALYST CARRIERS FOR USE IN ENVIRONMENTS INVOLVING THE PRESENCE OF STEAM, PARTICULARLY AT HIGH TEMPERATURES.
