Abstract: A data-constrained modelling（DCM）approach with multi-spectrum synchrotron X-ray CT was used to characterizing the physical structure of a direct coal liquefaction residue sample.The X-ray absorption properties of residue compositions were analyzed.Three sets of X-ray CT data were acquired with monochromatic beam energies at 14,16,and 20 keV respectively.The results show that the DCM can identify the unconverted coal matrix,asphaltene and heavy oil.However,the asphaltene and heavy oil are difficu... More
