Process for producing spherical catalyst particles containing a zeolite as active element, according to which a sol containing zeolite crystals and at least one gel-forming compound is sprayed from below directly into a reaction zone containing a reaction gas such that the sol breaks up into individual sol beads immediately before or upon entry into the reaction zone, the sol beads flow through the reaction zone on a curved trajectory, in so doing are pre-consolidated and the sol beads are collected on a collecting means.

Process for producing spherical catalyst particles, catalyst particles and their use in a chemical synthesis

A process for producing porous polymer beads in which polymers, preferably polyolefins or polyvinyl chloride, are dissolved in a solvent, preferably halogenated hydrocarbons or alkyl esters, at temperatures close to the boiling point of the solvent. The hot polymer solution is cooled, and the polymer beads formed during the cooling process are separated, washed and dried. The porous polymer beads are useful, for example, as catalyst carriers or as adsorption agents.

A method for the sorption of organic compounds using a sorbent, comprising activated carbon in a preferably amorphous oxidic support is described. Novel sorbents are also described.

Sorption of organic compounds from fluids

Disclosed is a product and process for the production of granules of high mechanical strength comprising mixing a molecular sieve and a metal oxide into a paste with a silicate, shaping the paste into granules, subjecting the shaped granules to an exchange of bases, drying the granules and tempering the granules at 300.degree. to 400.degree. C.

A process for the preparation of shaped bodies includes preparing a plastic mixture of a material selected from the group consisting of aluminum oxides, aluminum hydroxides, silicon oxides, silicon hydroxides and mixtures thereof from a predominantly dry component K1 in powdered form and a paste component K2 comprising water and additional additives, continuously extruding the plastic mixture into cut lengths, shaping the cut lengths into spherical shaped bodies and drying the spherical shaped bodies and optionally tempering such bodies to form catalyst and catalyst supports. The solids content of the powdered component K1 is from 65 to 100% by weight whereas the solids content of the paste component K2 is 10 to 50% by weight. Preferable spherical shaped bodies are based on Al.sub.2 O.sub.3, SiO.sub.2, or Al.sub.2 O.sub.3 /SiO.sub.2.
