本研究建立了一個通用的超重力旋轉床(RPB)模型，該模型能夠良好的預測臭氧在RPB中吸收的效果，同時能夠預測揮發性有機化合物(VOCs)在RPB中臭氧化的情形，且模型的預測結果能適用於所有VOCs種類的臭氧化，因此該模型能夠做為工業上處理VOCs放大製程的指標。
首先，本研究透過多筆的臭氧和氧氣吸收實驗數據驗證模型預測的效果，並從中篩選出適合用於RPB臭氧吸收的經驗式組合，為Onda的氣相質傳係數和Chen的液相質傳係數，透過該經驗式組合，模型的預測值與實驗值誤差分別為臭氧吸收的9.3%，和氧氣吸收的3.2%，同時了解到在該系統中，液相質傳阻力佔總質傳阻力的99%，氣相質傳阻力是可以被忽略的，該研究成果說明模型能夠良好預測臭氧及氧氣在RPB中吸收的效果。
接著，模型同樣透過多筆的實驗數據，分別驗證鄰甲酚和苯酚在RPB中臭氧化的效果，證實模型的通用性，在此我們了解到液相質傳阻力中的Hatta number使用VOCs的濃度時，預測值與實驗值分別高達97.5%和57.8%，若使用用於調整pH值的酸之濃度，預測值與實驗值誤差能分別降至7.3%和11.5%，並且在此系統中，氣相質傳阻力同樣能夠被忽略。
在多筆數據的驗證後，該模型的臭氧吸收預測，以及VOCs臭氧化的預測能夠符合文獻的實驗值，模型的準確性及通用性得到驗證，說明該模型能夠作為一個通用的模型，可做為工業發大製程的指標。

This study proposed a generic model for ozone absorption and volatile organic compounds (VOCs) ozonation in a rotating packed bed (RPB). The model considered comprehensive mass balances and gas-liquid mass transfer rates to supply flexible modifications for VOC applications and aimed to predict the ozonation for all kinds of VOCs. The model predictions can guide the industrial scale-up process for VOCs.
Numerous ozone-absorbed experimental data validated the model predictions, and a suitable combination of the mass transfer correlations was found through multiple comparisons in this study. The model applicability and universality were testified by two types of VOCs-ozonated experimental data (O-cresol and Phenol). The effect of gas-phase and liquid-phase mass transfer resistances was also investigated.
Results showed a suitable combination of the mass transfer correlations was found based on the ozone absorption validation. The combination employs Onda for gas mass transfer coefficient and Chen for liquid mass transfer correlations.
In the VOCs ozonation validation, we found that the Hatta numbers should be modified from the VOC concentration-based to pH-based to fit the experimental data. The AAD of cresol-ozonated and phenol-ozonated significantly improve from 97.5% and 57.8% to 7.3% and 11.5%, respectively. Furthermore, all the systems were found to be liquid-phase mass transfer dominant because the gas mass transfer coefficient is much larger than the liquid one. Therefore, the gas-phase mass transfer resistance was verified to be negligible.
In conclusion, after being validated with two-part experimental data successively, the model possesses the key factors to predict the ozone absorption and various kinds of VOCs ozonation in an RPB. Therefore, an effective and generic model to predict ozonation for all kinds of VOCs is present.
