Adsorbent for selectively reducing release amount of volatile carbonyl and phenol compounds in cigarette smoke and preparation method and application of adsorbent

Abstract

The invention discloses an adsorbent for selectively reducing the release amount of volatile carbonyl and phenol compounds in cigarette smoke and a preparation method and application of the adsorbent. The preparation method comprises the following steps of: preparing an aqueous solution of inorganic metal salt, directly spraying the aqueous solution on the surface of any one carrier material of activated carbon fibers, a zeolite molecular sieve, sepiolite, activated carbon and the like, performing drying treatment and preparing the adsorbent. When the adsorbent is applied to cigarettes in a binary composite filter stick form, the release amount of multiple volatile carbonyl compounds and phenol compounds in main stream smoke of the cigarettes can be greatly reduced while the sensory quality of the cigarettes is not obviously influenced. The adsorbent has the obvious effect of selectively reducing the cigarette harm, is extremely simple in preparation process, low in cost and safe, has the effect of environment protection, and has wide application prospects in the field of cigarette harm reduction, and the large-scale industrial production of the adsorbent is easily realized.

Description

technical field [0001] The invention relates to the technical field of reducing tar and harm of cigarettes and the preparation of cigarette filters, in particular to an adsorbent capable of selectively reducing the release of phenols and carbonyl compounds in mainstream smoke of cigarettes and its preparation method and application. Background technique [0002] Cigarettes undergo a series of chemical and physical changes such as pyrolysis, degradation, and distillation during the combustion process. The components of cigarette smoke formed are complex. More than 5,000 components have been identified, and volatile carbonyl and phenolic compounds are important among them. Harmful and carcinogenic ingredients. Studies have shown that volatile carbonyl compounds such as formaldehyde, acetaldehyde, and crotonaldehyde with less than five carbons can cause diseases through inhalation and skin absorption, especially crotonaldehyde is a highly toxic substance with cilia toxicity, an...

Chinese patent 201010542254.8 utilizes the characteristic that CN- has a strong complexation with metal ions, and different metal ions are complexed on a porous carrier with a large specific surface area to obtain a class of metal complex materials that can be used to selectively reduce cigarette smoke. The amount of HCN released in the air, but the preparation of complex materials has many processes and complicated procedures, and it is necessary to load three or more metal ions on the carrier

Using a metal ion adsorbent, it can selectively and greatly reduce various volatile carbonyl compounds and The release of phenolic substances, but also has a simple preparation process, can be mass-produced, and has application prospects. There are no relevant patents and literature reports in the field of cigarette harm reduction and tar reduction.
