Embodiment 1

[0022] Weigh 500g of ordinary peanut shells, adjust the water content to 15%, and then place it in a microwave expansion device, expand it for 30 seconds at a power of 800w, spray the expanded peanut shells with distilled water repeatedly, adjust the water content of the peanut shells to 22%, After standing under high temperature for 6 hours, put peanut shells in 1 kg of copper chloride aqueous solution (pH 3, concentration 5%), stir evenly for 2 hours at a solution temperature of 55°C, then cool naturally to room temperature, remove the solvent, and then Place in a microwave expansion device, dry and expand for 60 seconds under the condition of a power of 900W, and pulverize into particles with a particle size of 20 meshes to obtain the desired modified peanut shell porous material.

Embodiment 2

[0024] Weigh 1 kg of pearl-shaped peanut shells, adjust the water content to 15%, and then place it in a microwave expansion device, expand it for 60 seconds at a power of 1200w, and spray the expanded peanut shells with distilled water repeatedly to adjust the moisture content of the peanut shells to 26%. After standing under high temperature for 6 hours, put the peanut shells in 2.5kg of zinc sulfate aqueous solution (pH 2, concentration 20%), stir evenly for 2 hours at a solution temperature of 60°C, then cool naturally to room temperature, remove the solvent, Then place it in a microwave expansion device, dry and expand for 90 seconds under the condition of a power of 1000W, and pulverize into particles with a particle size of 60 mesh to obtain the desired modified peanut shell porous material.

Embodiment 3

[0026] Weigh 3kg of multi-grain peanut shells, adjust the water content to 18%, then place it in a microwave expansion device, expand it for 70 seconds at a power of 2500w, spray the expanded peanut shells with distilled water repeatedly, and adjust the water content of the peanut shells to 25%. After standing at room temperature for 8 hours, put the peanut shells in 8 kg of ferric chloride aqueous solution (pH 3, concentration 12%), stir evenly at a solution temperature of 90°C for 2 hours, cool naturally to room temperature, remove The solvent is then placed in a microwave expansion device, dried and expanded for 60 seconds under the condition of a power of 1000W, and crushed into particles with a particle size of 80 mesh to obtain the desired modified peanut shell porous material.

Abstract

The invention discloses a modified peanut hull porous material and application thereof to cigarettes. The porous material is obtained by performing procedures of microwave expansion, crushing granulation, modification with a modifier, microwave expansion drying and the like on peanut hulls. The modified peanut hull porous material is added to a cigarette filter to prepare a binary composite filter which is applied to the cigarettes, wherein the addition of the modified peanut hull porous material is 12 to 55 percent based on the total weight of the filter. Actual application shows that components such as tar, nicotine, hydrogen cyanide, phenol and crotonaldehyde in cigarette smoke can be effectively reduced. The modified peanut hull porous material is convenient to operate and low in cost, and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a porous material prepared by using peanut shells through chemical modification. At the same time, the invention also relates to the application of the porous material in cigarette processing. Background technique [0002] Peanut is the main oil crop in my country, and its total output and export volume both rank first in the world. my country's total annual peanut output reaches about 15 million tons, accounting for 42% of the world's total peanut output, and about 5 million tons of peanut shells can be produced every year. According to reports, the largest component of peanut shells is crude fiber, with a content of 65.7% to 79.3%. Other nutrients in peanut shells are also very rich, crude protein 4.8% ~ 7.2%, crude fat 1.2% ~ 1.8%, reducing sugar 0.3% ~ 1.8%, disaccharide 1.7% ~ 2.5%, pentose sugar 16.1% ~ 17.8%, Starch 0.7%, also contains some miner...
