Method for reducing release amount of carbon oxide of main stream smoke of cigarette

Abstract

The invention discloses a method for reducing the release amount of carbon oxide of main stream smoke of cigarette. A composite additive of nano metal oxide and chlorophyll is added into a cigarette filter stick and the amount of the composite additive added into the cigarette filter stick is 0.7-7 percent by mass of a cigarette; the nano metal oxide is formed by compounding iron oxide, copper oxide, manganese oxide and chromium oxide; the iron oxide accounts for 5-30 percent by mass of the nano metal oxide; the copper oxide accounts for 10-50 percent by mass of the nano metal oxide; the manganese oxide accounts for 15-40 percent by mass of the nano metal oxide; the chromium oxide accounts for 5-20 percent by mass of the nano metal oxide; the proportion of the nano metal oxide to the chlorophyll is 0.25:1-25:1; and the composite additive is obtained after mixing the nano metal oxide and the chlorophyll. The release amount of the carbon oxide in the main stream smoke of the cigarette can be reduced by 17-35.8 percent through combination of the nano metal oxide and the chlorophyll, so that the health of cigarette consumers is favorably protected.

Description

technical field [0001] The invention relates to the technical field of tar reduction and harm reduction of cigarettes, in particular to a method for reducing carbon monoxide emission in mainstream smoke of cigarettes. Background technique [0002] Cigarette burning and smoking is a process of high-temperature anoxic incomplete combustion, and the maximum temperature can reach about 950°C. When the cigarette is smoked, the combustion mainly occurs around the bottom of the combustion cone, the oxygen in the airflow is almost exhausted, and the oxidation process does not play a major role. The limited combustion leads to the simultaneous occurrence of distillation, dry distillation, pyrolysis, synthesis and other reactions, forming a large number of nascent compounds. Cigarette smoke is a complex multiphase aerosol in which gas, liquid, and solid coexist. According to reports, there are nearly 4,000 chemical components in cigarette smoke alone, more than 1,000 types in tobacc...

Problems solved by technology

This technology lowers the temperature in the combustion zone of cigarettes through the cracking of polyhydroxy organic acid salts to absorb heat, thereby reducing the purpose of cracking carbonyl compounds to generate CO. The disadvantage is that the temperature in the combustion zone is lowered, and the aroma precursors of cigarettes may directly enter the smoke without cracking. , leading to a decrease in the aroma of cigarettes
