Abstract: A set of experiments are carried out in a new kind of packed material,honeycomb paper,to investigate its regeneration performance varying with air flow and height of the honeycomb paper when the inlet air states,solution concentration and flow rate are fixed.The result and analysis are presented,and the optimal heights of honeycomb paper in different velocity of air inlet are also presented in this paper.

Key words: liquid desiccant； regeneration performance； structure of packed material； experiment study；
