- Description
- Methoxy aromatic compounds are important chemical intermediates with wide applications in industry, agriculture, and medicine. In this study, the production of bio-oil rich in methoxy aromatic compounds via microwave pyrolysis of Eucalyptus pulverulenta (EP) branch was investigated in the temperature range of 300-500℃. The results showed that 400℃ was the optimum temperature to achieve the highest yield of bio-oil (28.4 wt.%), where the concentration of methoxy aromatics in the biooil reached to 70.4 area%. The addition of Na2CO3 and K2CO3 has led to increases in the bio-oil yields. During the microwave pyrolysis of EP, Na2CO3 and K2CO3 increased the selectivity of methoxy aromatics in the bio-oil, while NaOH showed a negative impact on the selectivity of methoxy aromatics. Based on the findings of the study, the reaction pathways of methoxy aromatic compound formation during pyrolysis were proposed.
