Abstract: A process for forming plastic inorganic agglomerates from which inorganic catalysts or adsorbent bodies can be formed is disclosed. The process involves(a) dispersing a portion of said inorganic material as surface hydrated noncolloidal sized dry particles in a water-immiscible solvent;(b) titrating the dispersion with a controlled quantity of an aqueous phase in the presence of colloidal sized particles of the same or different inorganic material while mixing until a hydrous plastic agglomerate forms; and(c) separating said hydrous plastic agglomerate from said water-immiscible solvent.

Abstract: A carrier for olefin polymerization catalysts (or catalyst components) which is in spherical form and has a narrow particle size distribution is produced by reacting an anhydrous magnesium dihalide with an alcohol or a phenol in an inert organic solvent to obtain a complex compound; suspending this complex compound with vigorous stirring in the presence of a nonionic surfactant in an inert organic solvent at the melting point of the complex compound or higher; and adding an organoaluminum compound or a silicon halide to the suspension to react them to thereby form spherical solids.

Abstract: This invention relates to catalysts for gaseous phase fluorination of aliphatic chlorinated derivatives by hydrofluoric acid. The catalysts comprise chromium oxide microspheres obtained by a sol-gel process. This invention also relates to gaseous phase fluorination processes for aliphatic chlorinated derivatives utilizing these catalysts.

Abstract: A process of making a high purity, low surface area porous alumina support having improved crush strength and abrasion resistance which comprises employing with the alumina a small amount of barium aluminate or silicate during its manufacture.

Abstract: Spherical particles of alumina are prepared by agitating a slurry of solids comprising rehydratable alumina solids in water with a hot immiscible liquid to disperse droplets of the slurry in a continuous phase of the immiscible liquid. The droplets are shaped by interfacial surface tension and are hardened by heat while in the immiscible liquid, then are separated and calcined to produce finished spherical alumina beads. The preferred beads are of size less than one millimeter. These are used as supports for catalysts that are used in several oil refining processes such as hydrotreating for removal of sulfur or for reforming or cracking.
