【摘要】 在全球能源结构转型加速推进的背景下，生活垃圾资源化制合成气技术因兼备固废处理与清洁能源生产的双重效益备受关注。针对当前垃圾焚烧技术存在的二次污染及高碳排放问题，本研究聚焦生活垃圾复合热化学深度处置工艺，基于Aspen Plus模拟软件，构建生活垃圾衍生燃料（RDF）复合热化学转化制合成气模型，分析RDF热值、流化床流化气化剂种类和气化温度（1 300～1 500℃）对合成气产量及能量利用效率的影响。结果表明：随着RDF热值的升高（12.56～20.92 MJ/kg）,合成气中有效气（H₂和CO）体积分数、冷煤气效率、系统综合能效均显著提升，分别提升72.76%～85.97%、68.60%～70.90%和45.73%～51.88%。CO₂/O₂流化气化剂体系的合成气中有效气产量为775.7～783.9 Nm³/h,相较于H₂O/O₂体系，该体系有效气产量提升约2.8%,耗氧量降低约2.9%,有效气体积分数为81.56%～87.10%,冷煤气效率为69.45%～71.40%,系统综合能效为45.94%～48.80%,具有更高的气化效率。气流床气化温度每提升100℃,耗氧强度显著增大，有效气体积占比降低，冷煤气效率下降约2.1%,系统综合能效下降约1.6%。本研究可为生活垃圾无害化处置与资源化利用提供理论指导。更多还原

【Abstract】 As the global energy transition accelerates, syngas production from municipal solid waste has attracted significant attention. This approach combines solid waste treatment and clean energy production. However, conventional waste incineration often causes secondary pollution and high carbon emissions. To overcome these limitations, this study investigates an integrated thermochemical process for the deep treatment of municipal solid waste. An Aspen Plus-based simulation model is developed for syngas production through gasification of refuse-derived fuel（RDF）. The effects of RDF calorific value, the type of agent for fluidized-bed gasification, and gasification temperature（1 300-1 500 ℃） on syngas yield and energy efficiency are systematically examined. The results indicate that increasing the calorific value of RDF from 12.56 to 20.92 MJ/kg significantly improves system performance. The content of effective gases（H₂ and CO）, cold gas efficiency, and overall system efficiency increase to 72.76%-85.97%, 68.60%-70.90%, and 45.73%-51.88%, respectively. Under a CO₂/O₂ fluidizing gasifying system, the effective gas yield reaches 775.7-783.9 Nm³/h. Compared to the H₂O/O₂ system, the effective gas yield increases by approximately 2.8%, while oxygen consumption decreases by about 2.9%. The effective gas volume fraction ranges from 81.56% to 87.10%. The cold gas efficiency is 69.45%-71.40%, and the overall system efficiency is between 45.94% and 48.80%, demonstrating higher gasification efficiency. When the temperature of fluidized-bed gasification increases by 100 ℃, oxygen consumption significantly increases, and the volume fraction of effective gas decreases. The cold gas efficiency drops by approximately 2.1%, and the overall system efficiency decreases by about 1.6%. This research provides theoretical guidance for the safe disposal and resource recovery of municipal solid waste.更多还原
