Abstract

The invention provides a carbonaceous heat source of a carbon heating cigarette and a preparation method of the carbonaceous heat source. The carbonaceous heat source comprises a modified porous carbon material and flavors and fragrances adsorbed on the modified porous carbon material, wherein a metal oxide is loaded on a surface of the modified porous carbon material. The modified porous carbon material loaded with the metal oxide is obtained by modifying the porous carbon material, and the modified porous carbon material and the metal oxide on the surface of the modified porous carbon material both play a catalytic oxidation role, so CO and other miscellaneous gases generated in the combustion process react immediately and are removed, and the miscellaneous gases are eliminated from the source; besides, due to the fact that the porous carbon material has a rich pore structure, a huge specific surface area and a large number of oxygen-containing functional groups, after essence and fragrance are added into the porous carbon material, the porous carbon material has good adsorbability on the essence and fragrance, and therefore the cigarette is endowed with rich fragrance while offensive odor is eliminated, and the smoking quality of the carbon heating cigarette is improved.

Description

technical field [0001] The invention belongs to the field of novel tobacco products, and in particular relates to a carbon heat source of a carbon heating cigarette and a preparation method thereof. Background technique [0002] Low-temperature heating cigarettes are one of the important categories of new tobacco products. They generally deliver satisfaction and part of the tobacco aroma to consumers through heat-not-burn tobacco. Their appearance and consumption methods are also similar to traditional cigarettes. To a certain extent Adapt to and meet the physical and psychological needs of consumers. This "heat not burn" method enables the tobacco to be heated only at a lower temperature (ideal temperature range 200-500°C), avoiding the generation of tar and a large number of harmful compounds caused by the high temperature environment when the tobacco is burned, and because There is basically no sidestream smoke, no second-hand smoke, and no impact on the public environme...
