Iphrojekthi yokufaka i-2500Nm3/hi-methanol ekukhiqizeni i-hydrogenkanye nedivayisi engu-10000t/a liquid CO2, etholwe yi-TCWY, kuqedwe ngempumelelo.Lolu phiko seluke lwenziwa uphiko olulodwa futhi seluhlangabezane nayo yonke imibandela edingekayo ukuze luqale ukusebenza.I-TCWY iqalise inqubo yabo eyingqayizivele yale yunithi, eqinisekisa ukuthi ukusetshenziswa kwe-methanol ngeyunithi ngayinye kungaphansi kuka-0.5kg methanol/Nm3 hydrogen.Le nqubo ibonakala ngobulula bayo, ukulawula inqubo emfushane, kanye nokusetshenziswa okuqondile kwemikhiqizo ye-H2 kuphrojekthi yekhasimende ye-hydrogen peroxide.Ukwengeza, le nqubo inika amandla ukuthunjwa kwekhabhoni kanye nokukhiqizwa kwe-CO2 ewuketshezi, ngaleyo ndlela ikhulise ukusetshenziswa kwezinsiza.
Uma kuqhathaniswa nezindlela zendabuko zokukhiqiza i-hydrogen, njenge-electrolysis yamanzi,ukulungiswa kwegesi yemvelo, kanye ne-coke coke gasification, inqubo ye-methanol-to-hydrogen inikeza izinzuzo eziningana.Ifaka inqubo elula enesikhathi esifushane sokwakha, edinga ukutshalwa kwezimali okuncane uma kuqhathaniswa.Ngaphezu kwalokho, isebenzisa amandla aphansi futhi ayibangeli noma yikuphi ukungcoliswa kwemvelo.Izinto zokusetshenziswa ezisetshenziswa kule nqubo, ikakhulukazi i-methanol, nazo zingagcinwa futhi zihanjiswe kalula.
Njengoba intuthuko yezinqubo zokukhiqiza i-methanol hydrogen kanye nama-catalysts iqhubeka yenziwa, isikali sokukhiqizwa kwe-methanol hydrogen sikhula kancane kancane.Le ndlela manje isiyisinqumo esikhethwayo sokukhiqiza i-hydrogen encane naphakathi.Ukuthuthukiswa okuqhubekayo kwenqubo kanye nama-catalysts kube nomthelela ekukhuleni kwayo okukhulayo kanye nokusebenza kahle okukhulayo.
Ukuphothulwa ngempumelelo kwephrojekthi yokufaka kanye nokuzuzwa kwezimo zokusebenza kuphawula ingqophamlando ebalulekile ye-TCWY.Ukuzinikela kwabo ekwakheni ikhambi elisimeme nelisebenza kahle ekukhiqizeni i-hydrogen kube nezithelo.Ngokusebenzisa i-methanol njenge-feedstock, i-TCWY ayigcinanga nje ngokuqinisekisa ukukhiqizwa kwe-hydrogen ephumelelayo kodwa futhi iye yabhekana nenkinga yokubanjwa kwekhabhoni nokukhiqizwa kwe-CO2 ewuketshezi, okwenza le nqubo ihambisane nemvelo nakakhulu.Njengoba umhlaba uguqukela ekusaseni elisimeme kakhudlwana, ubuchwepheshe obufana nenqubo ye-methanol-to-hydrogen buzodlala indima ebalulekile ekuqinisekiseni indawo yamandla ehlanzekile neluhlaza.Ukuqaliswa ngempumelelo kwe-TCWY kwale nqubo kubeka isibonelo esihle embonini futhi kukhuthaze ukuhlola okwengeziwe nokwamukelwa kwezinye izindlela zokukhiqiza i-hydrogen.
