Chemistry of cigarette burning processes

Philip Morris USA, Research Center, Richmond, VA, USA

Cigarette burning processes and its smoke formation and composition are important topics for understanding cigarette performance. This paper proposes a basic chemistry model of the cigarette burning processes. The previous knowledge of the cigarette burning processes and smoke formation helped to establish the parameters in deriving the basic chemistry equations. The proposed chemistry explains the mechanisms of the cigarette burning processes during puffing and interpuff smoldering and predicts the deliveries of some smoke components for Bright, Burley, and Oriental cigarettes. Based on the proposed chemistry, the effect of ventilation on the smoke component delivery is discussed and the reaction heat of the puff-burning process is estimated.
