| Abstract: |
| Using HZSM-5 molecular sieve with ratio of silica to alumina 20∶?1 as catalyst,Jatropha curcas oil as raw material, and the mini fixed bed in laboratory as reactor,the catalytic pyrolysis reaction was conducted.The effects of pyrolysis temperature, weight hourly space velocity and dosage of catalyst on catalytic pyrolysis reaction were investigated to optimize the pyrolysis conditions.The results showed that the optimal pyrolysis conditions were obtained as follows: pyrolysis temperature 500?℃, weight hourly space velocity 2.72 h-1 and dosage of catalyst 33.3%(based on mass of raw material). Under these conditions, the conversion rate of Jatropha curcas oil was the highest,reaching 29.60%, and the deoxygenation rate was 53.77%. The product was mainly composed of aromatics. |
