豆类秸秆两级热解特性研究
Two-step pyrolysis characteristics of bean stalks
摘要
Abstract
Two-step pyrolysis of soybean stalk was investigated using pyrolysis-gas chromatography/mass spectrometry ( Py-GC/MS ) . The results indicate that with the increase of the first-step pyrolysis temperature ( t1 ) , the total peak area of the first-step products becomes higher. However, for the second-step, the total peak area decreases gradually with the increase of t1 . The products in the first-step pyrolysis have higher contents of acids, ketones and furans when t1 is 400 or 450℃. This is because that the products are originated from cellulose and hemicellulose. The content of hydrocarbon products in the second-step is more than 20% when t1 is 450 or 500℃. With two-step pyrolysis some products with high content can be obtained in the first or second step, respectively, such as acetic acid, furfural, guaiacol, methylbenzene and benzene etc. , thus preliminarily achieving the selective pyrolysis of biomass.关键词
