Abstract

Activated carbons of grades AG-5, SKT-6A, and LiderKarbon-E, impregnated with copper sulfate with an additive content of 10–20 wt % and modified with fullerenes in the amount of 0.003–0.006 wt % were prepared and studied. The introduction of additives reduces the volume of micropores up to 36% with a slight decrease in the volume of mesopores. Modification of activated carbon by fullerenes increases its dynamic benzene capacity in humid environments by 28–36%, and the introduction of fullerenes into a chemical adsorbent based on activated carbon modified with copper sulfate increases its dynamic ammonia capacity by 45–51%, especially at high air humidity.

基于活性炭的富勒烯改性氨化学吸附剂的生产与研究

摘要

制备并研究了AG-5，SKT-6A和LiderKarbon-E等级的活性炭，其中浸渍了添加剂含量为10–20 wt％的硫酸铜并经0.003-0.006 wt％的富勒烯改性。添加剂的引入使微孔的体积减少多达36％，而中孔的体积略有减少。在潮湿环境中，富勒烯对活性炭的改性可将其动态苯容量提高28％至36％，将富勒烯引入以硫酸铜改性的活性炭为基础的化学吸附剂中，其动态氨容量可提高45–51％，尤其是在空气湿度高。
