题目: Effect of pre-adsorbed water in zeolites with different pore structures on acetone adsorption performance
内容提要:

Zeolites with uniform pore structures are potential adsorbents for the volatile organic compounds (VOCs) adsorption. The pore structures of zeolites and the pre-adsorbed water contained in the adsorbents all affected the VOCs adsorption performance. In this work, we investigated the acetone adsorption performance of four zeolites with different pore structures and studied the effect of pre-adsorbed water vapor on the adsorption performance of acetone. The results showed that the acetone adsorption performance was affected by the specific surface area, pore size and pore volume of zeolite. The pre-adsorbed water had a negative influence on acetone adsorption capacities, which formed competitive adsorption between water vapor and acetone molecular. In addition, we measured and analyzed the difference between the ideal specific surface area and the actual specific surface area, which will provide a reference for actual industrial applications in the future.
