AbstractThe oligomerization performances of biomass cracking gas over amorphous silica-alumina(ASA) were investigated in a fixed bed in the region of 100-320 degrees C and 2.0-4.0 MPa. NH3-TPD, Py-IR, TG, SEM, BET and XRD were used to characterize the surface structures, acidity properties and carbon deposition of catalysts. The results showed that there were different degrees of acid amount loss and carbon deposition for ASA during oligomerization under different reaction conditions. The loss of Lewis acid amount decreased gra-dually with increasing temperature, and reached the minimum at 280 degrees C, and then begun to increase with continual increase of temperature. The increase of pressure is beneficial to reduce the Lewis acid loss. The change trend of carbon deposition was consistent with that of Lewis acid loss. During oligomerization, the conversion of light olefins and yield of gasoline range products increased gradually with the increase of temperature and pressure, and reached the maximum at 4.0 MPa and 280 degrees C. The conversions of ethylene, propylene and butylene reached 19.2%, 37.3% and 58.7%, respectively. The yield of gasoline range product reached 22.9%(molar fraction), and the selectivity of C5+ olefins reached 73.5%.
