Embodiment 1

[0020] Weigh 10g of sodium alginate, add 100mL of water, stir well to make it gelatinous, add gelatinous sodium alginate and add 10g CaCl 2 Aqueous solution, stirring rapidly and reacting quickly to generate alginic acid complex, filtering off water, drying in an oven at 80°C for 5 hours, and grinding in a grinder to obtain CaCl 2 composite material.

Embodiment 2

[0022] Weigh 20g of sodium alginate, add 200mL of water, stir well to make it gelatinous, add the gelatinous sodium alginate into the 2 25g of aqueous solution, stirred rapidly and reacted rapidly to form alginic acid complex, filtered off the water, dried in an oven at 60°C for 6 hours, and ground by a grinder to obtain CaCl 2 composite material.

[0023] The synthetic ammonia CaCl of example 1,2 2 There was no significant difference in the ammonia reduction effect of the complex composites.

Embodiment 3

[0025] Weigh 10g of sodium alginate, add 150mL of water, stir well to make it gelatinous, add the gelatinous sodium alginate into the 2 15g of aqueous solution, stirred rapidly and reacted rapidly to form alginic acid complex, filtered off the water, dried in an oven at 70°C for 7 hours, and was ground by a grinder to obtain CuCl 2 composite material.

Abstract

The invention provides an ammonia complex composite capable of selectively reducing ammonia in smoke. A preparation method of the ammonia complex composite comprises the steps that a certain amount of sodium alginate is weighed; water is added, and stirred fully to ensure that sodium alginate is jellied; a metal chloride solution with a certain concentration is added and stirred quickly, reacts, and is subjected to moisture removal, placed in a drying oven for drying, and ground by a grinding mill; and a sample is obtained. The composite is added to a filter stick of a cigarette, can selectively reduce ammonia in the smoke, is obvious in effect, low in production cost and high in adding safety, does not generate a negative effect on sensory quality of the cigarette, and has a good industrial application prospect, and the operation is easy and simple.

Description

technical field [0001] The invention relates to the preparation of an ammonia complex composite material and its application in selectively reducing ammonia in flue gas Background technique [0002] Ammonia is one of HOFFMANN's 44 hazardous components. The content of ammonia in fresh tobacco leaves is very small, and the content of ammonia in tobacco leaves increases due to reactions such as metabolic oxidation and deoxygenation of proteins and amino acids after modulation and fermentation. Amino acids, proteins, nitrates and ammonium salts in tobacco leaves are the precursors of ammonia in cigarette smoke. In cigarettes, an appropriate amount of ammonia is necessary for cigarettes with more carbohydrates and organic acids, and it and other nitrogen-containing compounds participate in the formation of smoke flavor. If the ammonia content is too low, the strength of the smoke will decrease and the plumpness will not be enough; but if the ammonia content is too high, it will...
