Embodiment 1

[0036] Drying: Remove impurities from pruned Zanthoxylum bungeanum, then air-dry or dry at 105±5°C.

[0037] Crushing: Break the dried Zanthoxylum bungeanum branches into craft wooden strips with a length of 5-10cm.

[0038] Charcoal activation reaction: put the obtained craft sticks into the rotary kiln, set the temperature rise rate of the rotary kiln to 1°C / min, the charcoal activation temperature to 400°C, the charcoal activation time to 4h, the rotary kiln speed to 0.5rpm, start After heating up, feed water vapor and keep the flow rate of water vapor at 1kg / h, so that the pore structure of the raw material will gradually develop, and finally become activated carbon.

[0039] Pulverization: After the activated material is cooled, the tilting angle of the rotary furnace is adjusted to 14°, and the activated carbon is taken out from the rotary furnace tube and pulverized to ensure that the particle size of the product activated carbon meets the specified requirements.

Embodiment 2

[0044] Drying: Remove impurities from pruned Zanthoxylum bungeanum, then air-dry or dry at 105±5°C.

[0045] Crushing: Break the dried Zanthoxylum bungeanum branches into craft wooden strips with a length of 5-10cm.

[0046] Charcoal activation reaction: put the obtained craft sticks into the rotary kiln, set the temperature rise rate of the rotary kiln to 10°C / min, the charcoal activation temperature to 700°C, the charcoal activation time to 3h, and the rotary kiln speed to 1.5rpm, start After the temperature rises, water vapor is introduced to keep the flow of water vapor at 10kg / h, so that the pore structure of the raw material is gradually developed, and finally becomes activated carbon.

[0047] Pulverization: After the activated material is cooled, the tilting angle of the rotary furnace is adjusted to 14°, and the activated carbon is taken out from the rotary furnace tube and pulverized to ensure that the particle size of the product activated carbon meets the specified...

[0052] Drying: Remove impurities from pruned Zanthoxylum bungeanum, then air-dry or dry at 105±5°C.

[0053] Crushing: Break the dried Zanthoxylum bungeanum branches into craft wooden strips with a length of 5-10cm.

[0054] Charcoal activation reaction: put the obtained craft sticks into the rotary kiln, set the temperature rise rate of the rotary kiln to 10°C / min, the charcoal activation temperature to 800°C, the charcoal activation time to 2.5h, and the rotary kiln speed to 1.5rpm, After starting to heat up, feed water vapor and keep the flow rate of water vapor at 20kg / h, so that the pore structure of the raw material will gradually develop, and finally become activated carbon.

[0055] Pulverization: After the activated material is cooled, the tilting angle of the rotary furnace is adjusted to 14°, and the activated carbon is taken out from the rotary furnace tube and pulverized to ensure that the particle size of the product activated carbon meets the specified requireme...

Abstract

The invention relates to a method for producing active carbon by pyrolysing pepper branches. The method comprises the following steps: a, detaselling the pepper branches, and airing or roasting and crushing; b, filling the crushed pepper branches by the step a in a rotary furnace, setting the temperature rising rate and temperature range of the rotary furnace, and heating to activate carbon in the presence of activating gases; and c, carrying out acid washing, water washing, drying, crushing and examination in a sieve, and then packaging the active carbon to prepare the product active carbon. Waste used by the invention not only solves the problem of multi-layer compound utilization of forest product pepper and greatly reduces the production cost of the active carbon, but also finds a novel resource capable of producing active carbon with high absorption for the active carbon industry.

Description

technical field [0001] The invention relates to the technical field of biomass pyrolysis, in particular to a method for producing activated carbon by pyrolyzing prickly pruned wood of prickly ash. Background technique [0002] Zanthoxylum bungeanum, also known as Qinjiao and Chuanjiao, is the fruit of deciduous shrubs or small trees of the genus Zanthoxylum in Rutaceae. It is a commonly used cooking seasoning and traditional Chinese medicine ingredient in the family. - Composed of eucalyptol, limonene and other substances, rich in polyunsaturated fatty acids (PUFAs), which have the functions of warming and dispelling cold, dehumidification, insecticidal and analgesic, and anti-tumor. Zanthoxylum bungeanum is planted in Japan, South Korea, North Korea, India, Malaysia, Nepal, the Philippines and other countries. Zanthoxylum bungeanum is widely distributed in our country. It is distributed in South China. Hancheng City, Baoji Chencang District, and Fengxian County are the cou...
