In summary, this study suggests that pyrrolidine and piperidine act as dual-function additives, promoting CH₄ hydrate formation while inhibiting CO₂ hydrate formation from both thermodynamic and kinetic perspectives. This unique characteristic presents a strong potential for CH₄/CO₂ separation via HBGS technology through the selective formation of CH₄ hydrate, as such additives have not been previously reported.</div></div>","PeriodicalId":381,"journal":{"name":"Journal of the Taiwan Institute of Chemical Engineers","volume":"173 ","pages":"Article 106166"},"PeriodicalIF":5.5,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
