Abstract:
Rising CO2 emissions and environmental pollution entail the need to develop advanced utilizing renewable energy technologies. Adsorption Cooling (AC) is a novel energy saving and environmentally benign technology, which allows effective utilization of solar or waste heat. The efficiency of AC greatly depends on the properties of adsorbents used. Metal-organic framework NH2-MIL-125 is considered promising for AC due to its step-wise isotherms of water adsorption and large adsorption capacity. Less data is available on the details of water transport in NH2-MIL-125 pores, although it is a crucial parameter for evaluating key performance indexes of AC. Here, the kinetics of water adsorption on loose NH2-MIL-125 grains was measured using an Isothermal Differential Step method. The effects of grain size and water uptake are studied. The rate limiting stages are determined and the corresponding water diffusivities are calculated. The data obtained are essential for optimization of AC cycles and adsorber configuration.
