Abstract

L'invention concerne une cigarette dotée d'un filtre (1) et comprenant une partie tabac (2) qui est composée de feuilles de tabac enroulées dans un papier à tabac et à laquelle est relié en continu un filtre (3). Ce filtre (3) est caractérisé en ce qu'il comporte une première partie (4) située côté bouche du fumeur et une seconde partie (5) placée entre la première partie (4) et la partie tabac (2), et en ce que cette seconde partie de filtre (5) contient une poudre produite au moyen d'un procédé consistant à malaxer des cendres volantes et de l'argile en tant que composants de base, et du dioxyde de titane, de l'oxyde de fer et une résine phénolique en tant que composants secondaires, de manière à produire une céramique poreuse, puis à pulvériser la céramique. On peut utiliser cette cigarette avec ce filtre (1) pour adsorber de manière sélective le goudron contenu dans la fumée du tabac et donc améliorer la capacité d'élimination du goudron.
