A process for the production of silica-bound zeolite granulates is disclosed, wherein zeolite to be formed into a granulate is mixed with silica sol. The process is carried out by adding aqueous alkali metal silicate to the silica sol immediately before the silica sol is mixed with the solid zeolite to be granulated. By the described process, granulates of various grain sizes can be obtained, and the resultant granulates can have a narrow grain size distribution.

Process for the production of molecular sieve granulates

A lacquer comprising an organic binder, at least one pigment or filler, and a zeolite in an amount sufficient to increase the dispersibility of the pigment or filler. Advantageously the pigment is at least one of titanium dioxide, iron oxide and mixed-phase rutile, and the binder is a polyester. Desirably the pigment is present in from about 1 to 5% by volume of the pigment plus any filler and its average particle size is from about 1 to 3 .mu.m.

Stabilizing pigmented lacquers with zeolites

A process for the production of synthetic zeolite with the crystal structure of faujasite and with a composition corresponding to the formula:

Production of synthetic zeolite of faujasite structure

In the production of a porous shaped inorganic structure wherein an inorganic solids-containing suspension is mixed with a gas-generating compound and the suspension is poured into a mold, the improvement which comprises employing as said gas-generating compound a molecular sieve zeolite laden with a gas.
