The static adsorption performance of honeycomb monolithic silica gel/molecular sieve composites（HMSMC）was tested，and their dynamic adsorption performance was also measured by using adsorbent bed to simulate the dehumidifying process of rotary-type dehumidifierThe distribution of temperature and humidity inside HMSMC during adsorption and the influences of processing air parameters，such as temperature，humidity and speed on adsorption performance were discussedThe results of experiments showed that the dehumidifying performance of HMSMC excelled honeycomb monolithic silica gel（HMSG），especially under high temperature and low humidity conditionsHMSMC had excellent dehumidifying ability under the low processing air temperature，low air speed，or high relative humidity condition.
