Abstract

The aim of this study was to develop five empirical and three mass-transfer based models for fitting the T. serpyllum SFE process. Additionally, the determination of the effect of SFE parameters (pressure, temperature, CO2 flow rate and mean particle size) on kinetic curves and model parameters was investigated. Among the selected models, all empirical and mass-transfer models provided adequate fit with experimental data. However, mass-transfer model VIII has proved to fit the experimental results accordingly and has shown that the most influential parameters were pressure and CO2 flow rate. The pressure and CO2 flow rate exhibited positive effect, while the temperature had rather negative impact on Y. In addition, the initial slopes of Model VIII were calculated in order to increase the efficiency and reduce unnecessary process costs.

通过超临界流体萃取实现野生百里香(Thymus serpyllum L.)药草灰尘的价值化--实验与建模
本研究的目的是建立五个经验模型和三个基于质量转移的模型,用于拟合蛇莓 SFE 过程。此外,还研究了 SFE 参数(压力、温度、二氧化碳流速和平均粒径)对动力学曲线和模型参数的影响。在所选模型中,所有经验模型和传质模型都与实验数据充分拟合。然而,质量传递模型 VIII 与实验结果的拟合度很高,而且表明影响最大的参数是压力和二氧化碳流速。此外,还计算了模型 VIII 的初始斜率,以提高效率和减少不必要的工艺成本。
