Abstract Agricultural residues are one of the large untapped sources of bio-energy in Thailand, with over 30 million tons available per year. They may be utilized to generate renewable liquid and solid fuels. In this work, pyrolysis of lignocellulosic biomass residues (corncobs, coconut shells, and bamboo residue) was carried out in an ablative pyrolysis reactor with rotating blades. Influences of inert carrier gas flows (5–15 L/min) and rotating frequency (4–8 Hz) at a fixed hot plate temperature of 500 °C on generating bio-oil were investigated. Characterization of bio-oil as well as biochar products was performed. Maximum bio-oil yield was found to be about 50% w/w for coconut shell at 5 L/min of flowrate and 8 Hz of the rotating frequency, and 45% w/w for bamboo residues at the same condition. For corncob, the highest bio-oil yield was 72% w/w at 5 L/min of flowrate and 6 Hz of the rotating frequency. Solid char yields were around 23–28% w/w. The heating values of the liquid oil and solid char were about 20–25 and 23–30 MJ/kg, respectively. Rotating blade ablative reactor was able to generate high yields of bio-oil for agricultural residues. The main compounds of the bio-oil obtained were phenolics, including furfuran, organic acids, aldehydes, alcohols, ethers, and ketones.

木质纤维素生物质残渣烧蚀热解生物油和生物炭的生产和表征

摘要 农业残留物是泰国尚未开发的大型生物能源来源之一,每年可利用的量超过 3000 万吨。它们可用于产生可再生的液体和固体燃料。在这项工作中,木质纤维素生物质残留物(玉米芯、椰子壳和竹渣)的热解在带有旋转叶片的烧蚀热解反应器中进行。研究了在 500 °C 固定热板温度下惰性载气流量 (5–15 L/min) 和旋转频率 (4–8 Hz) 对生成生物油的影响。进行了生物油和生物炭产品的表征。在 5 L/min 的流速和 8 Hz 的旋转频率下,椰子壳的最大生物油产量约为 50% w/w,相同条件下竹渣的最大生物油产量为 45% w/w。对于玉米芯,在 5 L/min 的流速和 6 Hz 的旋转频率下,最高的生物油产量为 72% w/w。固体炭产率约为 23-28% w/w。液态油和固态炭的热值分别约为 20-25 和 23-30 MJ/kg。旋转叶片烧蚀反应器能够为农业残留物产生高产量的生物油。所得生物油的主要化合物为酚类,包括呋喃、有机酸、醛类、醇类、醚类和酮类。
