Biomass staged gasification technology (BSGT) divides the traditional gasification into medium-temperature devolatilization (MTD) stage, high-temperature gasification (HTG) stage and high-temperature reforming (HTR) stage. The present study conducted MTD and HTG experiments on corn stalks and focused on the effect of MTD at 200–550 °C on the reforming performance of BSGT liquid products through component analysis and simulation. The results demonstrate that the MTD temperature above 350 °C could prevent the participation of phenols and oxygen in HTG and HTR stages, respectively, thereby improving the reforming performance of BSGT liquid products and the quality of BSGT syngas. The H2 production and H2/CO of the BSGT at MTD temperature of 350–550 °C increased by 1.81–5.01 mmol/g and 0.64–0.79, respectively compared to that of the traditional gasification. The findings of the present study are of great significance for achievement of high-value utilization of BSGT liquid products.

基于组分分析与模拟的生物质分级气化液体产物重整性能研究



生物质分级气化技术 (BSGT) 将传统气化分为中温脱挥 (MTD) 阶段、高温气化 (HTG) 阶段和高温重整 (HTR) 阶段。本研究对玉米秸秆进行了 MTD 和 HTG 实验,并通过组分分析和模拟,重点研究了 200–550 °C MTD 对 BSGT 液体产品重整性能的影响。结果表明,MTD 温度高于 350 °C 可以分别阻止酚类和氧参与 HTG 和 HTR 阶段,从而提高 BSGT 液体产品的重整性能和 BSGT 合成气的质量。与传统气化相比,在 350–550 °C 的 MTD 温度下,BSGT 的 H2 产量和 H2/CO 分别增加了 1.81–5.01 mmol/g 和 0.64–0.79。本研究结果对实现 BSGT 液体产品的高值化利用具有重要意义。
