选用3种商用活性炭及其分别经HCl溶液和KOH溶液浸渍改性的商用活性炭,研究中高温烟气环境下,反应空速、吸附温度对挥发性有机物(VOCs)吸附性能的影响,以及VOCs种类、吸附剂特性等与VOCs吸脱附效果的关系。研究发现:空速对吸附穿透时间影响较大,但对饱和吸附量影响不显著。吸附温度与VOCs浓度对饱和吸附量存在较大影响,150℃时甲苯的饱和吸附量仅能达到90℃时的40%。高沸点吸附质更易被吸附,更难被脱附。
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.
