Rice straw is an abundant resource for the production of biofuels and bio-based products. How to convert the recalcitrant lignocellulose effectually is a critical issue. The objective of this study was to investigate the products, mechanism, and kinetics of rice straw pyrolysis by using microwave heating. The highest energy densification ratio of solid residues was achieved at the microwave power level of 300 W. The atomic H/C and O/C ratios of solid residues were much lower than those of rice straw. The primary components of gaseous product were CO, H2, CO2, and CH4, whose molecular fractions were 57%, 21%, 14%, and 8%, respectively. The more gaseous product and the less solid residues were obtained at higher microwave power levels, while the liquid production remained the same and showed a maximum of about 50 wt.%. The kinetic parameters of rice straw pyrolysis were increased with increasing microwave power level.
稻草是生产生物燃料和生物基产品的丰富资源。如何有效地转化木质纤维素是一个关键问题。本研究旨在利用微波加热研究稻草热解的产物、机理和动力学。在微波功率水平为 300 W 时，固体残渣的能量密度比达到最高。固体残渣的原子 H/C 和 O/C 比远低于稻草。气态产物的主要成分是 CO、H2、CO2 和 CH4，其分子分数分别为 57%、21%、14%和 8%。在较高的微波功率水平下，得到了更多的气态产物和更少的固体残渣，而液体产物保持不变，最大值约为 50wt.%。稻草热解的动力学参数随着微波功率水平的增加而增加。
