针对目前垃圾衍生燃料(RDF)气化实验缓慢升温的问题,研究了RDF在氧气、氮气与水蒸气3种气氛条件下,500~900℃共5个温度点的快速气化特性。结果表明:O

具有强氧化性,在此气氛下气化产气会生成大量CO

,产气潜力最低;CO

气化氛围下则由Boudouard反应主导,合成气产量可观,但其单一的反应路径具有局限性;水蒸气气氛下可通过多重协同机制实现高产气率,产气效果最佳,总产气率为16.7 mmol·g

气氛下会促进芳构化,减少焦炭缩聚,水蒸气气氛下固体残留物含杂环结构,高温会抑制重组,导致轻质烃占比提升。
To address the issue of slow heating rates in current refuse-derived fuel (RDF)gasification experiments,the rapid gasification characteristics of RDF under three atmospheres (oxygen,nitrogen,and steam)at five temperature points (500—900℃)are investigated.Results show that O
2
exhibits strong oxidizing properties,leading to significant CO

production and the lowest gas generation potential.Under CO
2
atmosphere,the Boudouard reaction dominates,yielding considerable syngas but limited by its single reaction pathway.In contrast,the steam atmosphere enables high gas production rates through multiple synergistic mechanisms,achieving the best gasification performance with a total gas yield of 16.7 mmol·g

and CO

,demonstrating the superiority of steam in rapid RDF gasification.As the temperature increases,the tar components from gasification exhibit a forward shift in composition.Under O
2
atmosphere,solid residues enrich oxygen-containing functional groups,and aromatization is promoted,reducing coke condensa
tion.In the steam atmosphere,solid residues contain heterocyclic structures,and high temperatures inhibit recombination,leading to an increased proportion of light hydrocarbons.
