Solid Superacid-catalyzed Hydroconversion of Demineralized Shengli Coal Liquefaction Residue under Microwave Irradiation

摘要

Shengli coal liquefaction residue was demineralized; the demineralized Shengli coal liquefaction residue (DMSCLR) was then subject to non-catalytic and SO_4~(2-)/ZrO_2- or SO_4~(2-)/TiO_2-catalyzed hydroconversion in methanol under microwave irradiation. The results show that both, SO_4~(2-)/ZrO_2 and SO_4~(2-)/TiO_2, significantly catalyzed DMSCLR hydroconversion. The MESs of hydrogenated DMSCLR were analyzed with gas chromatography/mass spectrometer. The MESs and methanol-inextractable fractions of hydrogenated DMSCLR were characterized with Fourier transform infrared spectrometer.
