Abstract

The invention discloses a preparation method of an activated carbon for cigarettes and a product of the activated carbon for cigarettes and an application. According to the method, a jute rod is used as a raw material, the jute rod is carbonized and then pulverized into granules, under water vapor with flow rate of 450-480 g / h, after activation for 1-3 hours at 800-900 DEG C, the activated carbon for cigarettes is obtained after discharging, sealing and cooling. As the result shows, the activation rate of the activated carbon for the cigarettes obtained by the method can reach 47%, specific surface area is 996.38 m<2> / g, strength is 92.7f%, apparent density is 0.32g / Ml, ash content is 4.31, and water content is 5.12%, pH value is 7.67, which all reach or exceed national tobacco industry standard for the activated carbon for cigarettes; besides, the activated carbon has high iodine adsorption value (1184mg / g), methylene blue adsorption value (195.88 mg / g) and phenol adsorption value (202.04mg / g), and excellent pore structure, and is especially beneficial for removal of harmful gases in small molecules of the cigarettes.

Description

technical field

[0001] The invention relates to the field of functional materials used in cigarette filter rods, and more specifically, to a preparation method of activated carbon for tobacco, activated carbon for tobacco and its application. Background technique

[0002] Adding activated carbon to cigarette filters can absorb non-condensable gas-phase harmful components, such as acetaldehyde, benzene, toluene, isoprene, etc., reduce the harm of harmful components in smoke to human health, and improve the quality of cigarettes. Pumping quality. my country is a big country in the production and consumption of cigarettes. Activated carbon filter cigarettes can greatly improve the filtering effect on smoke and reduce harmful components in smoke. It is also easy to be accepted by consumers, and the cigarette industry will gradually become a huge potential market for activated carbon.

[0003] Activated carbon for tobacco refers to the physical activated carbon added during the ...
