Abstract

An integrated system combined direct air capture (DAC) and greenhouse agriculture is proposed, in which moisture swing adsorption technology is used to concentrate CO₂ from the atmosphere and then feed CO₂ to the greenhouse. Absorption isotherm study and desorption kinetic study have been achieved in the paper. The results show that the behaviour of membrane conforms to Langmuir model and its capacity reaches to 0.83 mol of CO₂ per kilogram of sorbent. When the output CO₂ concentration of the desorber is around 1000 ppm, desorption efficiency increases from 71.3% to 79.6% when the temperature is changed from 25°C to 40°C. Besides, based on the experiment of the uptake kinetics of plants under different light and different light intensity, energy consumption and techno-economic analysis of the system have been carried out.
