| 英文摘要 | Corn straw can be converted to bio-oil through pyrolysis. However, the application of bio-oil is severely restricted due to the high content of oxygen. Catalytic pyrolysis is an available way for deoxygenation of bio-oil, and the deoxygenation reactions are strongly dependent on the type of catalyst. Whereas, the correlation between the deoxy-genated products and the catalyst types is still far from clear. In this work, the migration of O in the pyrolysis process was investigated, and eight catalysts were screened for deoxygenation of bio-oil, with a lab-scale fixed-bed reactor. The results showed that with the increase of pyrolysis temperature, the content of O in bio-oil decreased below 400 degrees C and then became stable and finally increased rapidly after 550 degrees C, indicating that the range of 400-550 degrees C was the proper temperature for deoxygenation. Eight catalysts (ZSM-5, SAPO-34, ZnO, MgO, delta-Al2O3, gamma-Al2O3, acidified-alpha-Al2O3 and acidified-gamma-Al2O3) were tested, and it was found that a higher alkalinity of catalyst was favorable for decarboxylation of bio-oil with more produced CO2, while a higher acidity was promoted the decrease of alcohols and carbonyls with more generation of H2O and/or CO. MgO was judged as the optimal catalyst for deoxygenation of bio-oil. The quality of bio-oil under the catalysis of MgO was best, with higher H/C and lower O/C. |
