Solubility of carbon monoxide in bio-oil compounds

It was observed that SRK and PR EoS have similar predictive ability in comparison to PC-SAFT for a mixture of CO with weakly polar compounds in this study. A comparison between the performances of EoS models was made in two ways: first by setting the binary interaction parameter kij to zero, and second by adjusting a temperature-dependent binary interaction parameter (kij). All the models perform with comparable accuracy with adjusted binary interaction parameters. However, due to the large differences between the chemical and physical properties of the compounds in this study, it is challenging to make a general statement on which is the best model.
