Catalytic hydroconversion of Shaerhu subbituminous coal over an Ni-based MOF-derived carbon matrix superacid catalyst.

ABSTRACT: A magnetic solid acid, TFMSA/CNOFW, was prepared by impregnating trifluoromethanesulfonic acid (TFMSA) into a calcined nickel-organic framework (CNOFW) at room temperature. The extraction residue (ER) of Shaerhu subbituminous coal (SSBC) obtained by ultrasonic extraction with an isometric carbon disulfide/acetone mixed solvent was subjected to non-catalytic hydroconversion (NCHC) and catalytic hydroconversion (CHC) over the TFMSA/CNOFW in n-hexane at 300 °C for 4 h. The soluble portions from NCHC (SP_NCHC) and CHC (SP_CHC) were analyzed using a gas chromatograph/mass spectrometer. Results suggest that, compared with SP_NCHC, the introduction of the TFMSA/CNOFW dramatically improved the yield of SP_CHC (from 14.1% to 35.8%). Furthermore, arenes
