摘要
为助力江西省农业绿色低碳转型发展,通过分析超临界水气化反应机制、环境效益及工程瓶颈方法,结合江西省农业废弃物组分特征,阐述了超临界水气化技术在农业废弃物资源化利用、清洁能源制备等领域的创新应用潜力。研究表明:江西省年产农业废弃物9 452.05万t,经超临界水气化技术可生成富氢气体,全生命周期碳足迹趋近于零;模块化装置适配省内80%丘陵山地地形,降低收储运成本,且全程无PM2.5、二噁英排放,每处理1万t秸秆可减排CO_(2)1.96万t;技术闭环产业链通过氢能驱动农机、合成氨及冶金工业,可以实现水资源循环利用率提升。研究进一步揭示该技术的工程瓶颈,包括高温高压设备腐蚀、无机盐结垢及催化剂失活,并提出耐腐蚀合金材料、模块化设计及“产学研用”协同等解决方案。以期为江西省从传统农业大省向“零碳农业强省”转型提供一种创新的解决方案。
To support the green and low-carbon transformation of Jiangxi Province's agricultural sector,this study investigates innovative applications of supercritical water gasification(SCWG)technology in agricultural waste recycling and clean energy production.By analyzing SCWG reaction mechanisms,environmental benefits,and engineering bottlenecks in conjun-ction with the composition characteristics of agricultural waste in Jiangxi province.The research demonstrates,Jiangxi generates 94.5205 million tons of agriculural waste annually,which can be converted into hydrogen-rich gas through SCWG technology with near-zero lifecycle carbon footprint.Modular SCWG systems adapt to 80%of the province's hilly terrain,reducing collection-storage-transportation costs while eliminating PM2.5 and dioxin emissions.Each 10000 tons of processed straw achieves 19600 tons of CO_(2).The closed-loop technological chain enhances water recycling efficiency through hydro-gen-powered agricultural machinery,ammonia synthesis,and metallurgical applications.The study identifies critical engineer-ing challenges including high-temperature/pressure equipment corrosion,inorganic salt scaling,and catalyst deactivation,proposing solutions such as corrosion-resistant alloys,modular design optimization,and industry university-research-application collaboration.It is expected to provide an innovative solution for Jiangxi province's transfor mation from a tradi-tional major agricultural province to a"zero-carbon agricultural powerhouse".
