Method for preparing active carbon from lignin and polymer composites comprising active carbon prepared the same

摘要

The present invention comprises the steps of (a) sonicating lignin to obtain lignin from which impurities are removed; (b) preparing a mixture by mixing lignin from which impurities have been removed and a base; And (c) preparing activated carbon by carbonizing the mixture under argon (Ar) and hydrogen (H ₂ ) mixed gas; a method for producing lignin-derived activated carbon is provided. Thereby, lignin, a waste bio by-product, is efficiently used as an eco-friendly material, and the specific surface area is significantly improved compared to activated carbon produced by conventional acid treatment. By applying it to industrial parts, it is possible to reduce pollutants generated from parts by adsorption of pollutants such as volatile organic compounds.
