Tóm tắt

This study aimed to investigate the effects of expansion pretreatment on the chemical structure and reaction characteristics of tobacco pyrolysis. Systematic characterization of the pretreated feedstock was conducted to analyze changes in the physicochemical properties of the feedstock. The thermal conductivity and specific heat capacity of the tobacco decreased significantly after expansion pretreatment. Furthermore, the average pore diameter and pore volume of the feedstock increased, leading to a significant enlargement of the specific surface area from 0.18 to 0.46 m
