Abstract A new genotype of Miscanthus sacchariflorus Geodae-Uksae 1, which was recently collected from damp land in South Korea, was pyrolyzed in a bubbling fluidized bed reactor for bio-crude oil production. Comparing to woody biomass this has a remarkably economic advantage of very low water content, because it is collected after naturally dried in autumn. This biomass was ground and sieved to acquire the fine size less than 1 mm and fed into the reactor with feeding rate of 200 g/hr continuously. Four reactor temperatures, 400, 450, 500, and 550 °C were set to investigate the optimal temperature for highest bio-crude oil yield and quality. Proximate and ultimate analyses were done for both biomass and bio-crude oil to scrutinize the property change during the fast pyrolysis. Experimental results showed that the maximum bio-crude oil yield was obtained to be 51.88 wt% at the pyrolysis temperature of 500 °C. The maximum higher heating value (HHV) of bio-crude oil was determined to be 15.88 MJ/kg at 400 °C, which was similar to the original biomass. At the pyrolysis temperature of 400 °C, the moisture content of bio-crude oil was 19.46 wt% which was increased by 8.61 wt% than the original biomass. Overall fuel properties of miscanthus sacchariflorus Gedae-Uksae 1 was thought to be similar to the general woody bio-crude oil.

一株新基因型芒草-玉树1号生物质原油生产

摘要 最近从韩国潮湿土地上采集到的一种新基因型 Miscanthus sacchariflorus Geodae-Uksae 1 在沸腾流化床反应器中热解用于生物原油生产。与木质生物质相比，它具有非常低的含水量的显着经济优势，因为它是在秋季自然干燥后收集的。将该生物质研磨过筛至小于1mm的细粒，以200g/hr的进料速度连续进料到反应器中。设置了四个反应器温度 400、450、500 和 550 °C，以研究最高生物原油产量和质量的最佳温度。对生物质和生物原油进行了近似和最终分析，以检查快速热解过程中的性质变化。实验结果表明，在500 ℃的热解温度下，生物原油的最大产率为51.88 wt%。生物原油的最大高热值 (HHV) 在 400 °C 下测定为 15.88 MJ/kg，与原始生物质相似。在400°C的热解温度下，生物质原油的水分含量为19.46 wt%，比原始生物质增加了8.61 wt%。芒草 Gedae-Uksae 1 的整体燃料特性被认为与一般木本生物原油相似。46 wt%，比原生物质增加了8.61 wt%。芒草 Gedae-Uksae 1 的整体燃料特性被认为与一般木本生物原油相似。46 wt%，比原生物质增加了8.61 wt%。芒草 Gedae-Uksae 1 的整体燃料特性被认为与一般木本生物原油相似。
