[0003] The adsorption and desorption performance of activated carbon is an important indicator for evaluating its quality. There are many factors that affect the adsorption and desorption performance of activated carbon. Pressure is one of the important influencing factors. Under different pressure conditions, the adsorption and desorption performance of activated carbon is also different. In order to evaluate the adsorption and desorption performance of activated carbon under different pressure conditions, it is necessary to place it in different pressure environments for adsorption and desorption test experiments.

[0004] Therefore, there is an urgent need for a pressure swing adsorption and desorption test device for measuring the effect of activated carbon, so as to adjust the measurement pressure in the same device, thereby performing activated carbon pressure swing adsorption and desorption tests under different pressure conditions.
