Abstract
- Microwave-assisted hydroconversions of demineralized Shengli lignite liquefaction residue (DMSLLR) were investigated over different zeolites in methanol at 140°C. The catalytic effects of the zeolites on the yields and compositions of methanol-soluble portions (MSPs) as well as the structural features of the MSPs and methanol-insoluble portions (MISPs) were examined. The results show that the yields of the MSPs over different zeolites follow the order: HZSM-5 > Hβ > HY > HM; HZSM-5 and Hβ observably promoted DMSLLR hydroconversion to gas chromatography/mass spectrometry-detectable normal alkanes and oxygen-containing organic species, whereas much more arenes were detected in the MSPs from hydrotreated DMSLLR with HY and HM.
