Modified peanut hull porous material and application thereof to cigarettes

[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.

[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.

[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.
