Patent GB-590252-A (GB)
Title: Improved process for the manufacture of spherical particles
IPC: B01J2/08
Filed: 1945-04-12
Abstract: Spherical particles comprising natural or synthetic adsorbents, e.g., ball clay, bentonite, bauxite, pumice, kieselguhr, carbon, and synthetic gels are obtained by dispersing the adsorbent in water with the addition of a settable hydrosol, and suspending droplets of the dispersion in a water-immiscible liquid until they gel.  In some cases addition of a hydrosol is unnecessary as the adsorbent itself forms a settable hydrosol.  In examples, bentonite is dispersed in water alone or with silica or alumina sol and the mixture is dispersed in butanol.  Small particles are obtained by agitating the aqueous dispersion with the immiscible liquid; particles larger than 1mm. are obtained by maintaining the mixture quiescent, particularly by allowing the drops to descend slowly in a column of the liquid.
