摘要：

Silica gels that were made humidity indicating by impregnation of CoC12 were used for air drying in isothermal packed column. The effects of type of silica gel, packing height, particle size and air flow rate on breakthrough curves were studied. The breakthrough curves predicted by Rasmuson and Neretniek's analytical solution were in good agreement with experimental data. © 1990, Taylor & Francis Group, LLC. All rights reserved.
