Abstract：Objective To develop a set of solid amine-based removal device,so as to realize the integrated control of CO2 and humidity in manned lunar landing spacecraft.Methods The performance of the device in adsorbing and desorbing CO2 and H2O in different experimental conditions was studied and impact factors of the adsorption performance were investigated by monitoring the changes of CO2 concentration in the cabin,the changes of weight before and after adsorption and desorption,and the changes of temperature at the inlet and outlet of the device.Results The results showed that CO2 and humidity could be removed from the cabin atmosphere by the device;the CO2 adsorption performance of the device was significantly influenced by the temperature and humidity;while lowering the inlet temperature and the internal temperature of the device was beneficial to CO2 removal.Conclusions The optimization and improvement direction for the device in the future is to take measures to export the heat generated during adsorption,and to improve the heat utilization efficiency during desorption and reduce energy consumption.
