Abstract To reduce the exposure risk of potentially harmful cigarette smoke, the precise design of fiber raw materials is key to modifying pyrolysis product distributions in cigarette paper. This study investigates the effects of pulp/wood blending ratios on the physical properties, chemical composition, and pyrolysis behavior of cigarette paper. Results indicate that the pulp blending ratio reconstructs the chemical microenvironment – particularly the lignin/hemicellulose distribution – thereby inducing a directional shift in the pyrolysis pathway. At 900 °C, the total relative abundance of fused-ring aromatic compounds and benzenes decreased from 55.07 % (pure hemp pulp, S1) to 43.87 % (pure softwood pulp, S7), demonstrating that wood pulp incorporation significantly regulates product distribution. This work elucidates the intrinsic relationship among fiber composition, chemical microenvironment, pyrolysis behavior, and products distribution, providing a theoretical basis for designing cigarette paper with tailored pyrolysis product profiles. The results represent compositional trends under pyrolytic conditions and require further validation under standardized smoking conditions for extrapolation to actual cigarette smoke.
