Abstract: There is disclosed a process for receiving, storing and handling aluminum hydroxide wet hydrate, wherein the aluminum hydroxide wet hydrate is unloaded, optionally in batches, by means of a dumping means, e.g., a dump truck into a hopper which is equipped with a conveying means, e.g., a plate conveyor, the aluminum hydroxide wet hydrate supplied by means of a transporting apparatus, e.g., a double belt vertical conveyor, to a weighing means, e.g., a conveyor-type weigher and weighed, subsequently supplied to an aluminum hydroxide wet hydrate suspension tank, mixing the aluminum hydroxide wet hydrate in the tank with the amount of aqueous sodium hydroxide needed to produce a suspension of the aluminum hydroxide wet hydrate and producing a pumpable and meterable suspension of the aluminum hydroxide wet hydrate by heating to a temperature between 20 and 100.degree.C with the aid of a heating element and a stirrer.

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.
