英文摘要 | continuous pyrolysis of corncob hydrolysis residue, coupled with ex situ catalytic upgrading of the pyrolysis vapor, was investigated in the combined system of an auger reactor and a downstream fixed-bed reactor. the effect of the zeolite catalyst, usy (ultrastable y) and hzsm-5 (si/al=25, 38) and catalytic temperature on the raw bio-oil upgrading were discussed. the results showed the strong acidity of porous zeolite was essential for catalytic deoxygenation during upgrading pyrolysis vapor. hzsm-5 (25), with the strong acidity and acidic sites, had favored the deoxygenation conversion of carbonyl/carboxyl-containing oxygenates in the pyrolysis vapor, which decreased its content to 2.3 area% via the gc-ms analysis of the upgraded bio-oil. mono-phenols (phenol and alkylphenols) were enhanced to 53.2 area% over hzsm-5 (25), as compared with that of 17.3 area% during non-catalysis process. the addition of ex situ catalytic upgrading had improved the quality of organic big-oil at the expense of its yield. coke formation on the strong acidic sites by condensation of intermediates is detrimental to organic bio-oil yield. the increase of catalysis temperature at the fixed-bed reactor decreased oxygenate compounds to 7.1 area%, 23 area% and 1.9 area% at 450 degrees c, 550 degrees c and 650 degrees c, respectively, with 0.75 s of vapor residence time. the tg/dtg/dsc characterization of the used hzsm-5 (25) implied that the coke had deposited on the surface of hzsm-5 (25), which could be removed by combustion to recover its activity.
