不同气氛下杨树木屑的微波裂解特性研究
Microwave Pyrolysis Characteristics of Poplar Sawdust Under Different Atmosphere
摘要
Abstract
Microwave pyrolysis of sawdust under CO2 and N2 atmosphere was investigated respectively. The results showed that different atmosphere had effects on the composition of pyrolytic oil, the nature of coke and the composition of gas. The maximum bio-oil yield(28. 42% ) was obtained under N2 atmosphere at 900 W, the percentages of esters and phenols in the oil were 67. 2% and 20. 5% at 800W,respectively. The contents of acid, aldehydes and alcohols in pyrolytic product were low. The BET specific surface area of obtained coke was 125. 44 m2/g. CO2 affected the nature of bio-oil and coke by participating in the reaction. The maximum bio-oil yield(30. 05% ) under CO2 atmosphere was obtained at 800 W, the percentage of esters reduced to 45. 8% , and the phenols increased to 26. 4% . The contents of acid, aldehydes and alcohols had nearly doubled. The BET specific surface area of coke increased to 136. 85 m2/g. The CO2 atmosphere reduced the H2 content and increased the CO content in gas product.关键词
