I-Tailored Hydrogen ekhiqiza isitshalo ngegesi yemvelo

Isingeniso

Ukukhiqizwa kwe-hydrogen kusuka kugesi yemvelo kunezinzuzo zezindleko eziphansi kanye nomphumela obalulekile wesikali. Ucwaningo nokuthuthukiswa kobuchwepheshe bezinqubo ezintsha ezithuthuke kakhulu zokukhiqizwa kwe-hydrogen kusuka kugesi yemvelo kuyisiqinisekiso esibalulekile sokuxazulula inkinga yomthombo we-hydrogen oshibhile. Njengamandla ezimbonini asezingeni eliphezulu futhi ahlanzekile, igesi yemvelo inokubaluleka okubalulekile kwamasu ohlelweni lokuthuthukiswa kwamandla eShayina. Ngoba igesi yemvelo ayiyona nje uphethiloli obalulekile empilweni yabantu yansuku zonke, kodwa futhi iyisisetshenziswa esiyisisekelo semikhiqizo eminingi yesibili yamakhemikhali.

Ukukhiqizwa kwe-hydrogen ngegesi yemvelo kungenye yemikhiqizo eminingi yegesi yemvelo. I-Liaohe Oilfield, njengendawo yesithathu ngobukhulu kawoyela negesi e-China, inothile ngemithombo yegesi yemvelo, ikakhulukazi emabhizinisini okucubungula uwoyela negesi. Enqubweni yokukhiqizwa kukawoyela negesi, singakhiqiza isilinganiso esikhulu segesi eyomile ehambisanayo, enezimo eziyingqayizivele zokucutshungulwa kwegesi yemvelo ejulile, Inokubaluleka okusebenzayo okubanzi ekukhuthazeni ukuthuthukiswa nokuthandwa kwenqubo yokukhiqiza igesi yemvelo i-hydrogen.

Ukukhethwa nokuhlaziywa kwethiyori kokukhiqizwa kwe-hydrogen kusuka kugesi yemvelo

Njengomkhiqizo wamakhemikhali wesibili, i-hydrogen isetshenziswa kakhulu ezimbonini zemithi, zamakhemikhali amahle, zikagesi nezikagesi. Ikakhulukazi, i-hydrogen, njengowoyela okhethwayo wamangqamuzana kaphethiloli, izoba nethemba elibanzi lemakethe emkhakheni wezokuthutha kanye nokukhiqizwa kwamandla esikhathini esizayo, futhi izothatha isikhundla esibaluleke nakakhulu esakhiweni samandla esizayo. Izindlela zendabuko zokukhiqiza i-hydrogen, njengokuguqulwa kwesitimu esilula se-hydrocarbon, i-electrolysis yamanzi, ukuqhekeka kwe-methanol, ukufakwa kwegesi yamalahle nokubola kwe-ammonia, sezivuthiwe. Nokho, kunezinkinga “eziphezulu nezimbili eziphansi” njengezindleko eziphezulu, isivuno esiphansi kanye nokusebenza kahle kwezisebenzi. Enqubweni yokukhiqizwa kukawoyela negesi e-Liaohe Oilfield, kunezinsiza ze-hydrocarbon ezifana negesi eyomile ne-naphtha. Ukusebenzisa le ndlela ukukhiqiza i-hydrogen kungakhulisa ukusetshenziswa kwezinsiza. Ngaphezu kwalokho, ingxenye eyinhloko yegesi yemvelo ehlobene nayo i-methane, engaguqulwa ibe yi-hydrogen ngesitimu se-hydrocarbon, ngokuhlanzeka okuphezulu kokukhiqiza nokusebenza kahle kokukhiqiza okuphezulu.

Umgomo wenqubo wokukhiqizwa kwe-hydrogen kusuka kugesi yemvelo

Izinqubo eziyinhloko zokucubungula igesi yemvelo zifaka i-atmospheric and vacuum distillation, ukuqhekeka kwe-catalytic, ukuguqulwa kwe-catalytic kanye nokukhiqizwa kwe-aromatics. Ngesikhathi esifanayo, kuhlanganisa ukuxhashazwa kwegesi yemvelo, ukuqoqa nokudlulisa nokuhlanza. Ngaphansi kwengcindezi ethile, izinga lokushisa eliphezulu kanye ne-catalyst, ama-alkanes nesitimu kugesi yemvelo kusabela ngamakhemikhali. Igesi eshintshayo ingena kusiguquli ngemva kokushintshana kokushisa kubhayela ukuze iguqule i-CO ibe yi-H2 ne-CO2. Ngemuva kokushintshaniswa kokushisa, ukufingqa nokuhlukaniswa kwamanzi esitimu, igesi idlula ngokulandelana embhoshongweni we-adsorption ofakwe ama-adsorbent akhethekile amathathu ngokulawulwa kohlelo, futhi i-N2, Co, CH4 ne-CO2 iyacindezelwa futhi ikhangiswe yi-pressure swing adsorption (PSA) ukuze kukhishwe umkhiqizo. i-hydrogen. Ukuhlaziywa kwe-Depressurization kukhipha ukungcola futhi kuvuselele i-adsorbent

Ifomula yokusabela: CH4 + H2O → CO + 3h2-q CO + H2O → CO2 + H2 + Q
