基于超临界水气化的江西农业废弃物制氢技术:应用潜力与工程瓶颈OA

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 94.520 5 million tons of agricultural 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 10 000 tons of processed straw achieves 19 600 tons of CO2.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".
