Abstract
The invention relates to a preparation method of a porous composite material for reducing harmful substances in flue gas. The preparation method comprises the following steps: allowing reactions to take place among tetraethylorthosilicate, Fe(NO3)3.9H2O, Ce(NO3)3.6H2O, NaOH, hexadecyltrimethylammonium bromide, sodium laurate and water, and calcining to obtain the porous composite material. The porous composite material can significantly reduce polycyclic aromatics, CO, crotonaldehyde and other harmful substances in flue gas.
Description
[technical field]
The present invention relates to the preparation of additive in the cigarette filter.More specifically, the present invention relates to a kind of composite porous preparation method who is used for reducing the flue gas harmful components, product that this method obtains and the application in cigarette filter.
[background technology]
The CO that mainly is present in the cigarette smoke gas phase that produces in the cigarette smoking process is a kind of harmful typical material.The carbon monoxide that the thermal cracking of tobacco produces is about 30%, all the other multiple harmful components such as polycyclic aromatic hydrocarbons (PAHs), NH
3, HCN, nitrosamine etc. supervene.Wherein in a single day CO is inhaled into human body and just combines with hemoglobin, forms highly stable carbonyl haemoglobin.Carbonyl haemoglobin makes histanoxia in case formation just makes hemoglobin lose the ability of delivery of oxygen, causes tissue hypoxia disease.Carbon monoxide can also influence the permeability that blood fat sees through blood vessel, and the generation and the development of chronic obstructive pulmonary disease also had facilitation.Therefore carbon monoxide is a kind of very harmful flue gas material.
In addition, the low molecule group compounds of aldehydes and ketones in the cigarette smoke is another kind of important harmful substance, has been put into the list of 7 kinds of cigarette smoke nuisance compositions with CO.Low molecule group compounds of aldehydes and ketones has stronger cilium toxicity, and wherein crotonaldehyde toxicity is the strongest, and long-term contact can cause rhinitis chronic, nervous system function obstacle etc.
At present, many achievements in research concentrate on the binary composite filter tip that contains nano-noble metal (containing Au, Pd, Ti) catalysis material, though this filter stick has good catalytic effect, its catalytic activity needs just can develop at the special producing environment.These methods of while are used noble metals to process catalysis material and are added in the filter tip, just can reach the purpose of CO catalytic oxidation under low temperature, so unavoidably will increase the cost that cigarette is made, general manufacturer is difficult to accept; And since the complexity of cigarette burning and the inactivation of smoke condensate at catalyst surface deposition and catalyst still do not have the applied catalysis material in the present industry and be added on the cigarette product appearance that can effectively reduce flue gas CO, crotonaldehyde and polycyclic aromatic hydrocarbons (PAH) (PAHs) in the cigarette.
This patent is developed and is suitable for the porous nanometer material catalyst that tobacco industry is used, and adds metals such as Fe, Al and Ce, and this catalysis material is made an addition in cigarette shreds or the filter tip, and effectively CO catalytic oxidation is CO
2, and utilize that metal effectively reduces harmful components such as crotonaldehyde in the cigarette smoke, polycyclic aromatic hydrocarbons (PAH) (PAHs) and nitrosamine in the porous material.
