Abstract：Biodiesel with high boiling point and low viscosity was used as the absorbent of non-polar volatile organic compounds (VOCs). In this contribution, toluene, tetrachloroethylene, styrene, and chlorobenzene were taken as the representatives of VOCs, and the absorption experiments were taken under different partial pressures and different absorbtion temperatures. The toluene absorption capacity of biodiesel was increased proportionally as the initial concentration increased. Temperature was a sensitive factor of absorption, and the increased temperature would lead to the decreased absorption capacity. Compared to mineral oil and water for toluene absorption, the toluene capacity of biodiesel was much higher when the absorption performed under the same concentration and temperature. In addition, the results also showed that the capacity order of four VOCs by biodiesel was styrene (55.17mg/g) > chlorobenzene (27.75mg/g) > tetrachloroethylene (29.46mg/g) > toluene (11.93mg/g). The solubility data were calculated according to the UNIFAC model. The average relative error was 3.37%, indicating that this model was not only in good agreement with the experimental data but also could effectively predict the VOCs absorption property of biodiesel. Furthermore, the thermodynamics of four VOCs solubility in biodiesel were also investigated, including infinite dilution activity coefficient, Henry coefficients, ΔG、ΔH and ΔS.
