Catalyst for reducing CO release guantity in main flow smove of cigarette, its preparation method and application

Abstract

The general formula of the catalyst is Au(a) Pt(b) Pd(c) Ni(d) Co (e) Fe(f) Cu(g) Zn(h) Ti(i) O(j) / carrier, in which a is 0.05-3.0 wt%, b is 0.05-3.0 wt%, c is 0.05-3.0 wt%, d is 0.0-20.0 wt%, e is 0.0-45.0 wt%, f is 5.0-40.0 wt%, g is 3.0-30.0 wt%, h is 0.0-75.0 wt%, i is 0.0-70.0 wt% and j is the rest. The active components of the catalyst and adjuvant are distributed on the carrier in nano size. Said invention can be used in the cigarette, and can be used for reducing CO release amount in the main flow smoke by 20-45%.

Description

technical field

[0001] The invention belongs to the field of tobacco. Specifically, the invention particularly relates to a catalyst for reducing the emission of carbon monoxide in mainstream smoke of cigarettes, a preparation method and application thereof. Background technique

[0002] Carbon monoxide is a gas harmful to health and one of the main harmful components in cigarette smoke. During the burning process of cigarettes, a large amount of carbon monoxide will be produced, and carbon monoxide is easy to combine with the hemoglobin in the human body, resulting in a decrease in blood oxygen delivery, which is harmful to the human body. At present, the governments of various countries are very concerned about smoking and health issues. For example, the European Union has clearly stipulated that in 2004, its marketed cigarette products must be lower than the requirements of "tar 10mg / stick, nicotine 1mg / stick, and carbon monoxide 10mg / stick". Therefore, it is of great pr...
