Abstract: The tobacco product carries on its surface catalytically active material for improving the burning process. The catalytically active material is selected from the group of crystalline and non-crystalline oxides and hydroxides of aluminium, e.g. gibbsite, having a particle size of 1 to 100 &mgr;m and a specific surface of 75 to 250 m2/g. With the use of the catalyst in the tobacco, the amount of noxious compounds in the mainstream and sidestream smoke can be considerably reduced in the combustion process of the smokers' article during its consumption.

Abstract: 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'Qwherein M is a monovalent cationM' is a divalent cationM" is a trivalent cationa', 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 andQ 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.
