中高温环境下VOCs在活性炭上的吸附性能研究
Study on adsorption capacity of VOCs on activated carbon at medium-high temperature
摘要
Abstract
A total of 5 kinds of activated carbons were selected, including 3 kinds of commercial activated carbons, one of which was impregnated with HCl solution and KOH solution, to study the influence of space velocity and adsorption temperature on the adsorption of volatile organic compounds (VOCs), and the influence of types of VOCs and characteristics of adsorbents on the adsorption and desorption of VOCs at high temperature and low concentration. It was found that the space velocity had a great effect on the adsorption penetration time, but did not affect the adsorption capacity. Adsorption temperature and the concentration of VOCs was found to have a great influence on the adsorption capacity, and when the adsorption temperature was 150℃, adsorption capacity of adsorbent to toluene can only reach 40% of that at 90℃. High-boiling adsorbates are more easily adsorbed and more difficult to desorb.关键词
