摘要：

The effect of TCNE addition on the extraction of coals of different rank with carbon disulfide-N-methyl-2-pyrrolidinone (CS2-NMP) mixed solvent (1:1 by volume) was investigated. TCNE increases considerably the extraction yields for some coals among the coals examined. TCNE seems to be effective for the coals that have much of heavy extract fraction, i.e., pyridine-insoluble extract fraction (E-PI). The effect of TCNE addition on the solubility of E-PI and other lighter extract fractions, and characterization of the solubilized fraction fractions by TCNE, suggest that the extraction yield enhancement by TCNE described above may be attributed to the suppression of association between coal molecules.
