| The solubility of Maoming oil shale kerogen is studied by using the CS2 - N-methyl-2-pyrrolidinone mixed solvent extraction. It is found that Maoming oil shale kerogen contains abundant soluble fractions (255.95 g/kg TOC). These solvent-soluble molecules are distributed or 'trapped' in the networks with abundant noncovalent bond interactions between soluble and insoluble molecules. |
