    摘要： The smoker's article comprises a filter, a tobacco rod and a wrapper. The tobacco rod contains 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.sub.m' M'.sub.n' M".sub.p �a'AlO.sub.2 .multidot.b'SiO.sub.2 .multidot.c'TO.sub.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, m', n', p or c' can also be zero, Al and Si are tetrahedrally coordinated Al and Si atoms, T is a tetrahedrally coordinated 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. The said catalyst consisting of a zeolite or the zeolite-like material, enclosed in the tobacco rod is present optionally in the H form and has a thermally stable structure. The sorbate Q is mainly water. The zeolite catalyst which is incorporated in the tobacco rod, especially in combination with the zeolite sorbent incorporated in the filter, reduces harmful products in the main and side stream smoke.
