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. |
