Abstract

The solubility of hydrogen in a Wilsonville ITSL coal derived liquid was estimated using the UNIFAC group contribution method. Functional group concentrations estimated from analytical data were combined with literature values of group contribution parameters to provide reasonable estimates of hydrogen solubility. A sensitivity analysis indicated that the most significant structural features in determining hydrogen solubility were aromatic ring size, the length of alkyl substituents and the concentration of aromatic hydroxyl groups.
