纤维乙醇残渣Py-GC/MS催化热解实验研究

large amount of residue was produced in cellulosic bioethanol production process. Catalytic pyrolysis of the residue to produce aromatics was carried out using Py-GC/MS in this paper. The effects of different kinds of large or medium pore catalysts (CaO, FCC, CP814E, et al) in catalytic pyrolysis were studied. On this basis, the mixture of two kinds of catalysts (including one microporous zeolite catalysts) was using for catalytic pyrolysis. The results of catalytic pyrolysis with single catalyst and mixed catalysts were well compared. The results showed that the bond breaking catalyst can preliminarily achieve deoxgenation. In addition, the mixed catalysts are more likely to generate higher octane number with more branched hydrocarbons production.
