Embodiment 1

[0034] Take 0.25 g Ni(NO 3 ) 2 ·6H 2 O, 0.5 g Co(NO 3 ) 2 ·6H 2 O, 50 g Cu(NO 3 ) 2 ·3H 2 O, 0.5 g C 16 h 36 o 4 Ti, 0.1 g YCl 3 ·6H 2 O, 4.6 g ZrClO 2 ·8H 2 O, 5.0 g Mn(NO 3 ) 2 ·6H 2 O and 60 g CeCl 3 ·7H 2 Dissolve O in deionized water, heat up to 30°C after complete dissolution, adjust the pH value to 9 with ammonia water, and after the reaction is stable, add 4A molecular sieve carrier that is 1 times the weight of the active component that has been dissolved in deionized water, and continue stirring. Stand still, filter, wash with deionized water and alcohol, age and dry at 120°C for 12 hours, then bake at 500°C for 10 hours, cool to room temperature and pulverize to 360 mesh. The above additives are analyzed by transmission electron microscopy, and the active catalytic components and additives are dispersed on the carrier in nanometer size, and the particle size is between 5-10nm, see figure 1 .

Embodiment 2

[0044] Take 0.25 g Ni(NO 3 ) 2 ·6H 2 O, 0.5 g Fe(NO 3 ) 3 9H 2 O, 50 g Cu(NO 3 ) 2 ·3H 2 O, 0.5 g C 16 h 36 o 4 Ti, 0.1 g YCl 3 ·6H 2 O, 4.6 g ZrClO 2 ·8H 2 O, 5.0 g Mn(NO 3 ) 2 ·6H 2 O and 50 g CeCl 3 ·7H 2 O was dissolved in deionized water. After the dissolution was complete, the temperature was raised to 40°C, and the pH value was adjusted to 11 with KOH. After the reaction was stable, the insoluble matter in the solution was filtered out, washed with deionized water and alcohol, and aged and dried at 120°C. After 10 hours, it was calcined at 450° C. for 6 hours, cooled to room temperature, and pulverized to 400 mesh.

[0045] Dissolve and dilute the above-mentioned additives with ethanol, add 58.5 g of diluent (11.7 g of the additive) to 1170 g of shredded tobacco, and evenly add it to the shredded tobacco after dilution, place it at room temperature for 12 hours for absorption, and make cigarettes according to the conventional process.

Embodiment 3

[0050] Take 0.25g Ni(NO 3 ) 2 ·6H 2 O, 0.5 g Co(NO 3 ) 2 ·6H 2 O, 50 g Cu(NO 3 ) 2 ·3H 2 O, 0.8 g Zn(NO 3 ) 2 ·6H 2 O, 0.4 g C 16 h 36 o 4 Ti, 0.1 g YCl 3 ·6H 2 O, 4.6 g ZrClO 2 ·8H 2 O, 4.0 g Mn(NO 3 ) 2 ·6H 2 O and 65 g CeCl 3 ·7H 2 O is dissolved in deionized water. After the dissolution is complete, the temperature is raised to 30°C, and the pH value is adjusted to 9 with ammonia water. After the reaction is stable, a porous alumina carrier that is 0.5 times the weight of the active component that has been dissolved in deionized water is added. Continue Stir, stand still, filter, wash with deionized water and alcohol, age and dry at 90°C for 10 hours, then roast at 650°C for 4 hours, cool to room temperature and pulverize to 300 mesh.

[0051] Dissolve and dilute the above-mentioned additives with ethanol, add 29.2 g of diluent (5.85 g of the additive) to 1170 g of shredded tobacco, and evenly add it to the shredded tobacco after dilution, place it at...

Abstract

The invention belongs to the technical field of the cigarette materials, in particular to an additive for reducing cigarette smoke carbon monoxide (CO), meanwhile, the invention also relates to a preparation method and an application thereof. The additive comprises the following components in percentage by weight: 10-60%of transition metal oxides of active catalytic component, 10-50% of assistantrare earth metal oxides and / or rare earth metal salt, 0-80% of carrier, wherein, the weight of the carrier is 0-10 times of the active catalytic component. The transition metal oxides and the rare earth metal oxide catalyst adopted by the invention has lower cost than the noble metal catalyst, simple preparation process and strong pointedness, can reduce the carbon monoxide in the cigarette smokewith the efficiency of 5-15% when added into tobacco under the premise that the prior process technology and the original performance is not changed, thus improving safety and comfort in the process of the cigarette smoking and improving and enhancing the taste quality of the cigarette by a certain degree.

Description

(1) Technical field [0001] The invention belongs to the technical field of cigarette materials, and particularly relates to an additive for reducing CO in cigarette smoke, and meanwhile, the invention also relates to the preparation and application of the additive. (2) Background technology [0002] Carbon monoxide (CO) is a gas harmful to health and one of the main harmful gas components in cigarette smoke. Cigarettes will produce a large amount of carbon monoxide during the burning process, and carbon monoxide is easy to combine with hemoglobin in the human body, resulting in a decrease in blood oxygen delivery and causing harm 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 cigarettes must meet the requirements of less than "tar 10mg / stick, nicotine 1mg / stick, and carbon monoxide 10mg / stick". Therefore, the technical re...
