ABSTRACT:
Hard, rounded aggregates are produced by preparing droplets of a slurry consisting of suspending liquid containing distinct particles of a solid and dropping the droplets of the slurry onto a bed of particles under conditions where the suspending liquid of the slurry droplet is removed. This technique is especially desirable for making unique fixed-bed catalysts.
