Abstract (en)

Use of spherical carbon in flue gas adsorption of a heat-not-burn tobacco product. The spherical carbon of a particular structural parameter, as well as doping it in a cartridge, is particularly advantageous for improving the content of harmful substances in flue gas due to the excellent selectivity and specific adsorption effect of a large number of carbonyl compounds produced during the heating of the heat-not-burn tobacco product, and even undesirable adsorption of nicotine is significantly improved.
