A study on the structure of Yilan oil shale kerogen based on its alkali-oxygen oxidation yields of benzene carboxylic acids, 13C NMR and XPS

The structure of YL kerogen was studied and a structural model was constructed based on the distribution of benzene carboxylic acids (BCAs) from oxidation of the kerogen, combined with its ultimate analysis, 13C NMR, FTIR, XRD, XPS, analysis of carboxyl and phenolic hydroxyl groups.372
