Sulphur speciation in bitumens and asphaltenes by X-ray absorption fine structure spectroscopy

The S L-edge and K-edge XANES spectra were collected on bitumen and asphaltene samples as well as model compounds in order to determine the feasibility of monitoring transformations of organic sulphur in bitumen during genesis, processing, and upgrading. Using the spectra of model compounds as finge...
