Description

Detailed Description of the Invention

[0001] This application claims priority to a prior application bearing patent number 202011453514.4 and entitled "Application of Spherical Carbon in Smoke Adsorption of Non-Combustion Heat-Not-Burn Tobacco Products," filed with the State Intellectual Property Office of the People's Republic of China on December 11, 2020, which is incorporated herein by reference in its entirety.

[0002] [Technical field] The present invention relates to the application of spherical carbon in the adsorption of smoke from non-combustion heated tobacco products, and belongs to the field of smoke adsorption from non-combustion heated tobacco products.

[0003] [Background technology] With the growing concern about the health of smoking, the demand for healthy smoking is also becoming stronger. In the tobacco industry, compared with traditional cigarettes, the development of new tobacco products is progressing rapidly, and new tobacco products are mainly divided into two types: smoked and smokeless. The smoked type is mainly divided into electronic cigarettes and non-combustion heated tobacco (HNB), and the non-combustion heated tobacco is divided into cigarette type and non-cigarette type. The main raw material of the cartridge in the cigarette type is traditional shredded tobacco, tobacco sheet or reconstituted midrib cut, and the main raw material of the cartridge in the non-cigarette type is nicotine-free herb particles, and flavor beads may be placed between the raw material and the mouthpiece, and different flavor beads are incorporated according to preference. The cigarette type non-combustion heated tobacco retains more of the tobacco flavor, making it more acceptable and easier for the general consumer to convert.

[0004] Compared with traditional cigarettes, non-combustion heated tobacco products utilize the special heating temperature of the smoking device to heat the cartridge without burning it, thereby significantly reducing the release of harmful substances (HPHCs). However, the tobacco part of the cartridge of non-combustion heated tobacco products is usually composed of tobacco sheets, flat tobacco, reconstituted tobacco leaves or herb particles, etc., to which a large amount of smoke injectors, flavors and fragrances and other substances have been added, and the smoke injectors are mainly composed of propylene glycol and glycerol, so a large amount of carbonyl compounds are generated during the heating process. These carbonyl compounds mainly include, but are not limited to, formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone, butyraldehyde, etc., which are considered to be important harmful components of smoke. Specifically, formaldehyde is classified as a class I carcinogen, acetaldehyde is classified as a group 2B by the International Agency for Research on Cancer (IARC), and may also be ciliary toxic, and acrolein is cytotoxic. How to effectively reduce harmful substances is currently an important direction in the research of new cigarettes, especially non-combustion heating cigarettes.

[0005] [Summary of the invention] In order to improve the above technical problems, the present invention provides a use of spherical carbon for smoke adsorption in non-combustion heated tobacco products.

[0134] Test Example 1 Smoke adsorption test of non-combustion heating type cartridge 1 and cartridge 2 The cartridge was formed by combining the composite nozzle rod 1 with at least one of a hollow filtration section, a temperature reducing section, a solid filtration section, or a tobacco section (tobacco sheet, tabular tobacco, or reconstituted tobacco leaf).

[0135] Specifically, the cartridge having the structure shown in FIG. 1 is composed of a hollow composite nozzle rod 1, a temperature-reducing section 2, a hollow filtration section 3 and a tobacco section 4, which are connected together.

[0136] The structure of the hollow composite nozzle rod 1 is as follows: the center is an empty part containing spherical carbon, and both ends are tow parts formed by low resistance tow. The manufacturing process of the hollow composite nozzle rod is as follows: the tow is cut into uniform pieces, molding paper is used for the exterior, and by adjusting the operating speed of the composite machine, the tow pieces are fixed to the molding paper with hollow intervals of about 6 mm, and then spherical carbon is uniformly added to the hollow intervals, and the hollow composite nozzle rod is manufactured by winding and molding by rotation.

[0137] Cartridge 1 and Cartridge 2 were manufactured according to the amount of spherical carbon filled and the particle size. In Cartridge 1, the amount of spherical carbon filled was 15 mg, and the spherical carbon XH-1 produced in Example 1 with a particle size range of 0.2 to 0.4 mm was selected as the spherical carbon. In Cartridge 2, the amount of spherical carbon filled was 30 mg, and the spherical carbon DH produced in Example 3 with a particle size range of 0.6 to 0.8 mm was selected as the spherical carbon. Comparative Example 1 used coconut shell activated carbon (among which the coconut shell activated carbon has an average pore size of 1.7268 nm and a specific surface area of ​​983 m) used in the commercially available "Haorizi" cigarettes from Shenzhen Tobacco Factory. 2 / g and a pore volume of 0.4244 cm 3 / g), and the amounts of coconut shell activated carbon added in the comparative examples were two specifications of 15 mg and 30 mg.

[0138] The cartridges were placed in a non-combustion heated smoking device and heated; there were at least three non-combustion heated smoking devices and at least 120 cartridges.

[0139] The cartridge is heated by the smoking device, and the generated smoke is collected and analyzed, and the analysis standard refers to YC / T 254-2008 or the European Union TPD Directive. The main harmful substances detected include, but are not limited to, aldehyde-ketone substances such as formaldehyde, acetaldehyde, acetone, acrolein, propionaldehyde, crotonaldehyde, 2-butanone, butyraldehyde, etc. Through the inspection, the content of harmful substances in the smoke of the non-combustion heated tobacco product containing activated carbon provided by the embodiment is significantly lower than that of Comparative Example 1, especially the content of a large amount of carbonyl compounds generated during the heating process of the smoke generator is significantly lower, indicating that the spherical carbon produced in the embodiment has excellent selective and specific adsorption effect on carbonyl compounds.

[0140] Test Example 2 Smoke adsorption test of non-combustion heating cartridge 3 In this embodiment, the structure of the cartridge 3 is substantially the same as that of Test Example 1, except that the tobacco part 4 is filled with a commercially available tea-scented tobacco sheet, the inhalation part is covered with a silica gel sheet with uniformly distributed pores, and is filled with 30 mg of the spherical carbon XH-2 of Example 2. The cartridge of Comparative Example 2 is a cartridge that does not contain spherical carbon or other activated carbon, and is also called a "blank cartridge."

[0141] Cartridge 3 and Comparative Example 2 were heated under the same conditions using a smoking device, and the results were compared using CORESTA RECOMMENDED METHOD N. 0 Referring to the measurement method of 74, the smoke generated by inhaling an electronic cigarette with a smoking machine was passed through an impact bottle filled with an acidic 2,4-DNPH (2,4-dinitrophenylhydrazine) solution, and the carbonyl compounds in the smoke were absorbed into the solution. The solution that collected the carbonyl compounds was analyzed by high performance liquid chromatography (HPLC-UV) connected to an ultraviolet detector to measure the content of aldehyde and ketone substances, and the measurement results are shown in the table below.

[0142] [Table 2]

[0143] The results showed that due to the adsorption effect of Cartridge 3, the content of harmful substances in the smoke of non-combustion heated cigarettes was significantly lower than that of the blank cartridge, and the content of aldehyde and ketone compounds was significantly lower. In particular, the adsorption rate for acetone (content after adsorption by Cartridge 3 / content in Comparative Example 2 × 100%) reached as high as 100%, and the adsorption rate for acetaldehyde exceeded 70%, demonstrating that the spherical carbon produced in the embodiment has excellent selective and specific adsorption effect on carbonyl compounds in smoke.

Any modifications, equivalent replacements, improvements, etc. made within the scope of the present invention that do not deviate from the gist and principles of the present invention are included within the scope of the claims of the present invention.
