Abstract

Conversion of corn straw into biochar by pyrolysis was considered as an environmentally friendly and efficient method for biomass sources because porous biochar has excellent properties and wide applications. Porous biochar production from corn straw in a microwave heated reactor was the main purpose of this study. The yields and microstructures of biochar produced at different pyrolysis temperatures (500, 600, 700, 800, and 900 °C), microwave powers (600, 650, 700, 750, and 800 W), and pyrolysis times (30, 40, 50, 60, and 70 min) were studied. The results showed that biochar yield ranged from 44.69 to 59.90 wt% with the changes of reaction conditions. Biochar with the nanoscale pores was first obtained at pyrolysis temperature of 800 °C, microwave power of 600 W, and pyrolysis time of 30 min, indicating that corn straw biochar had the potential to produce nanoscale pores. This study also quantitatively described the relationship between microstructure and productivity of corn straw biochar at different experimental conditions (pyrolysis temperature, microwave power, pyrolysis time), which can provide guidance for the reuse of corn straw and the production of porous biochar.

在微波加热反应器中热解玉米秸秆生产多孔生物炭
通过热解将玉米秸秆转化为生物炭被认为是一种环保、高效的生物质源方法,因为多孔生物炭具有优异的性能和广泛的应用。本研究的主要目的是在微波加热反应器中利用玉米秸秆生产多孔生物炭。研究了在不同的热解温度(500、600、700、800 和 900 ℃)、微波功率(600、650、700、750 和 800 W)和热解时间(30、40、50、60 和 70 分钟)下生产的生物炭的产量和微观结构。结果表明,随着反应条件的变化,生物炭的产量在 44.69 至 59.90 wt% 之间。在热解温度为 800 ℃、微波功率为 600 W、热解时间为 30 min 的条件下,首次获得了具有纳米级孔隙的生物炭,表明玉米秸秆生物炭具有产生纳米级孔隙的潜力。该研究还定量描述了不同实验条件(热解温度、微波功率、热解时间)下玉米秸秆生物炭的微观结构与生产率之间的关系,可为玉米秸秆的再利用和多孔生物炭的生产提供指导。
