Summary: The study explores the application of pressure swing adsorption (PSA) for removing and recycling VOCs, with a focus on nonequilibrium time, effective length, and enrichment ratio. Various experiments were conducted to investigate the mechanism and industrial parameters of PSA, revealing that factors such as kinetic diameter, polarity, pore size, and boiling point influence the efficiency of VOCs removal. Methanol and acetone showed shorter effective lengths for complete removal compared to toluene, and the desorption performance was found to be related to desorption activation energy and the boiling point of the adsorbate. Ultimately, the study found that acetone had the highest recovery ratio among the three VOCs studied, presenting new opportunities for VOCs removal and recovery.

Summary: Activated carbon filters are extensively used to eliminate gaseous pollutants for ensuring a healthy living environment. However, the current standard method for evaluating their adsorption performance at 100 ppm concentration is insufficient compared to the actual contaminant concentration in indoor environments. This study compared different methods and recommended a procedure based on the Wheeler-Jonas model to estimate breakthrough curves at low concentrations using experimental data at high concentrations.
