mouthwash and tissues, or can be used to treat odors in
household areas (page 5, lines 55-58). Gloffre teaches that
the molecular sieves can be in shaped forms, i.e., monoliths,
but does not discuss how the shaped forms are made (page 5,
lines 53-55).
Hakansson discloses a method for making a cellular body
for adsorption of preferably organic substances in
purification plants (abstract). The cellular body is made by
binding layers, preferably layers of inorganic artificial
fibers such as glass fibers, by impregnating the layers with a
sludge made of hydrophobic zeolite and an inorganic binder,
and heating the impregnated body at a temperature at which
sintering of the constituents begins to occur (page 2, lines
1-8 and 26-29; page 3, lines 1-6). The zeolite can be a
dealuminized zeolite, and the inorganic binder includes clay
(page 3, lines 16-19). When the clay is a kaolin-type clay of
an alkaline nature or alkaline additives are used with the
clay, “the pH value should be as high as possible without the
hydrophobic properties of the zeolite being negatively
affected” (page 3, lines 20-23). The impregnated cellular
body “is fired at a temperature causing sintering together of
