商用活性炭对乙酸酯类挥发性有机物的动态吸附
Dynamic adsorption of acetate volatile organic compounds by commercial activated carbon
摘要
Abstract
VOCs are critical precursors of PM2.5 and ozone pollution,and controlling their emission is one of the main ways to reduce PM2.5 concentration and O3 pollution.Activated carbon adsorption method is a widely used VOCs control method due to its advantages of high energy efficiency,economy and environmental friendliness.The dynamic adsorption behavior of ester organic compounds was systematically studied using granular activated carbon(AC)as adsorbent.The results showed that for the ester organics with similar molecular structure,the saturated adsorption capacity of ester compounds on AC had a good positive correlation with the molecular weight,and a negative correlation with the saturated vapor pressure.The dynamic simulation results showed that both Thomas and Yoon-Nelson models could well describe the adsorption behavior of ester organics on AC.The former had a high degree of fitting on the adsorption breakthrough curve,and the latter had a more accurate prediction of the semi-saturation time.The kinetic results showed that Bangham equation was better than the pseudo-first order and pseudo-second order equations for fitting the kinetic model of AC adsorption of ester organics.关键词
