Abstract

The invention discloses a method for preparing activated carbon by using waste wool, which specifically comprises the following steps of: firstly, cutting waste wool into pieces, heating to 260 DEG C in a tubular reactor under the protection of nitrogen, pyrolyzing for 30min to 60min to form initial carbon with a tubular structure; secondly, evenly mixing the initial carbon and a powdered activator together according to a certain mass ratio, activating the mixture in the tubular reactor at high temperature, heating to 400-700DEG C, and then preserving the temperature for 30-90min, and coolingto the room temperature and taking out; and finally cleaning and drying to obtain finished activated carbon made from waste wool. By the method for preparing activated carbon provided by the invention, the pollution caused by the waste wool is avoided; and simultaneously, based on the special structure of wool, the prepared activated carbon is of a tubular structure and has special performances and purposes; and the pollution is not produced in the whole production method basically, so the production method meets the requirements of clean production and recycling economy, and has great marketvalue and social benefit.

Description

technical field

[0001] The invention belongs to the fields of material chemical industry and environmental science, and relates to a method for preparing activated carbon, in particular to a method for preparing activated carbon by using waste wool. Background technique

[0002] my country is rich in wool resources. It is the world's largest sheep breeding country, the second largest wool producer, and the largest wool importer. It is also a major wool textile producer. Due to the limitation of wool quality, feeding management and textile technology, a large amount of wool short fibers and crude fibers are discarded every year; at the same time, many worn wool sweaters are discarded, which not only causes a waste of resources, but also pollutes the environment. Therefore, it is of great significance to study the recycling and utilization of waste wool fibers and their methods for the effective utilization and protection of natural resources and the realization of sustainable...
