Abstract: A method of preparing spheroidal eta-alumina particles. An acidic alumina hydrosol is commingled with a gelling agent and dispersed as droplets in a hot oil suspending media to form firm, spherical, hydrogel particles. The particles are washed at a temperature of from about 25* to about 60* C., and at a pH of at least about 5.5, with an aqueous salt solution having a salt concentration substantially equivalent to that of the aqueous phase of the hydrogel particles. The salt concentration is reduced during the washing process until the wash-water is saltfree and the pH is adjusted to at least about 9. Spheroidal bayerite alumina particles are produced which, upon calcination, yield spheroidal eta-alumina particles.

Abstract: There is disclosed the preparation of high purity, high surface area, porous beads of silicon oxide doped with small quantities of other oxides, which preparation comprises hydrolyzing a silicon alkoxide dissolved in a hydroxyl containing organic solvent with less than a stoichiometric amount of water so as to provide a partially hydrolyzed intermediate product. The resulting partially hydrolyzed intermediate product is then treated with additional water and an immiscible non-polar organic medium so as to form a discontinuous phase of liquid partially hydrolyzed intermediate product dispersed in a continuous phase of organic medium. As a source of dopant oxide, a selected water soluble salt is added to the process at any convenient step prior to the next process step of pH adjustment, e.g. before, during, or after the partially hydrolyzing; before, during, or after the organic medium treatment. The dispersed intermediate product is then treated with a base and a quantity of water sufficient to hydrolyze any residual alkoxy groups in the dispersed intermediate product. The resulting mixture is stirred until the dispersed intermediate is converted to firm, hard, solid, porous beads of silicon oxide doped with at least one other oxide. The beads are typically recovered by filtration and evaporation of non-solid residues or by like method.

Abstract: Shaped bodies of a molecular sieve zeolite having an improved mechanical hardness greater than 5 kp are produced by spraying an unstable silicic acid sol as the binder on to a zone of the rotating plate of a granulating device and concurrently applying the pulverized zeolite particles to another zone of the rotating plate, while avoiding the formation of a plastic mass, and the thus produced shaped bodies are dried and activated according to the disclosed process. The unstable silicic acid sol has a silicic acid content greater than 10 percent by weight and a BET surface greater than 150 m2/g.

Abstract: A method of preparing amorphous alumina spheres. An acidic alumina hydrosol is commingled with a neutralizing or gelling agent and dispersed as droplets in a hot oil suspending media to form firm, spherical, hydrogel particles. The particles are transferred after forming to an aqueous salt solution with a pH of at least about 5.5, and with a salt concentration substantially equivalent to that of the aqueous phase of the hydrogel particles. The salt concentration of the aqueous solution is reduced gradually until the solution is salt-free. Amorphous alumina spheres are recovered upon drying.
