摘要： The smoker's article comprises a filter, a tobacco rod and a wrapper. The filter comprises a sorbent consisting of a hydrophobic member of zeolites or zeolite-like molecular sieves, the zeolite or zeolite-like material being defined by the following formula:

M m M' n [aAlO 2 · b SiO 2 ·cTO 2 ] q Q

wherein

M is a monovalent cation,
M' is a divalent cation
a, b, c, n, m, and q are numbers which reflect the stoichiometric proportions,
c, m, n or q can also be zero,
Al and Si are tetrahedrally coordinated Al and Si atoms,
T is a tetrahedrally coordinated metal atom being able to replace Al or Si
and
Q is a sorbate molecules corresponding to the pore geometry of zeolite,
the modulus a/b of the zeolite or the zeolite-like material, enclosed in the filter, has a value >400 and the pore size of the sorbent lays wihin the range of 5 to 7 Å;
and/or the smoker's article contains a tobacco rod containing a catalyst consisting of a hydrated zeolite or a zeolite-like molecular sieve, the said zeolite or zeolite-like material being defined by the following formula:

M m' M' n' M'' p [a' AlO 2 · b' SiO 2 ·c' TO 2 ] q' Q

wherein

M is a monovalent cation
M' is a divalent cation
M'' is a trivalent cation
a', b', c', n', m', p and q' are numbers which reflect the stoichiometric proportions,
c', m', n', p' or q' can also be zero,
Al and Si are tetrahedrally coordinated Al and Si atoms,
T is a tetrahedrally coordinated metal atom being able to replace Al or Si
and
Q is a sorbate capable of passing the pore system of the zeolite,
or of mixtures thereof, which characterized in that the catalyst consisting of a zeolite or the zeolite-like material, enclosed in the tobacco rod is present at least in part in the H form, the Q is mainly water and that the catalyst comprises a thermally stable structure.
The zeolite sorbent incorporated in the filter reduces harmful products in the main stream smoke and the zeolite catalyst which is incorporated in the tobacco rod reduces harmful products in the side stream smoke
