Process for use of molecular sieve adsorbent blends

A Process for the production and uses of a molecular sieve adsorbent blend product with improved performance characteristics produced by preparing a zeolite powder, preparing a highly dispersed attapulgite fiber binder, mixing the zeolite powder with the highly dispersed attapulgite binder to form a mixture, forming molecular sieve adsorbent products into a shaped material and calcining the shaped material, wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml.

Analysis of volatile organic compounds in water and air using attapulgite clays

The purge and trap procedure commonly used for analysis of volatile organic compounds in water or air can be significantly improved using traps employing clays and modified clays as adsorbents. Examples of clays include attapulgite clay, attapulgite clay modified with tetrasodiumpyrophosphate, carboxymethylcellulose and the combination thereof, kaolin clay, kaolin clay modified with tetrasodiumpyrophosphate, carboxymethylcellulose or the combination thereof, and mixtures of the above clays.

Absorbent materials

Absorbent material comprising clay mineral particles, the particles comprising compacted masses of relatively smaller particles is found to have high absorbency which may be further increased by the use of additives such as silicates, pyrophosphates, swelling clays, polysaccharides or polyvinyl pyrrolidone. Preferred are smectites, attapulgite or sepiolite preferably in the form of particles in below 1.4 mm, preferably below 710 microns in the size range compacted into larger particles in the 710 micron to 4 mm size range. The absorbent particles are suitable for use as pet litter.
