Isityalo esivelisa iHydrojeni esilungiselelwe ukusuka kwirhasi yendalo

Intshayelelo

Imveliso yeHydrojeni esuka kwirhasi yendalo ineengenelo zexabiso eliphantsi kunye nesiphumo esibalulekileyo sesikali. Uphando kunye nophuhliso lweteknoloji yenkqubo entsha ephucukileyo yokuvelisa i-hydrogen evela kwigesi yendalo sisiqinisekiso esibalulekileyo sokusombulula ingxaki yomthombo we-hydrogen ophantsi. Njengomgangatho ophezulu kunye nococeko lwamandla oshishino, igesi yendalo inokubaluleka kobuchule obubalulekileyo kwinkqubo yophuhliso lwamandla eTshayina. Ngenxa yokuba igesi yendalo ayikho nje into ebalulekileyo yokubasa kubomi bemihla ngemihla yabantu, kodwa kunye neyona nto isisiseko yeemveliso ezininzi zeekhemikhali zesibini.

Imveliso ye-Hydrogen esuka kwigesi yendalo yenye yeemveliso ezininzi zegesi yendalo. I-Liaohe Oilfield, njengendawo yesithathu enkulu ye-oyile kunye negesi yegesi e-China, izityebi kwimithombo yegesi yendalo, ngakumbi kwi-oyile kunye ne-gas centralized processing amashishini. Kwinkqubo yokuveliswa kwe-oyile kunye negesi, sinokuvelisa isikali esikhulu segesi eyomileyo ehambelanayo, eneemeko ezizodwa zokusetyenzwa kwegesi yendalo, inokubaluleka okusebenzayo okubanzi ekukhuthazeni uphuhliso kunye nokuthandwa kwenkqubo yokuvelisa igesi yendalo ye-hydrogen.

Ukukhethwa kunye nohlalutyo lwethiyori yemveliso ye-hydrogen ukusuka kwigesi yendalo

Njengemveliso yeekhemikhali yesibini, i-hydrogen isetyenziswa kakhulu kumayeza, kwimichiza emihle, kumashishini ombane kunye nombane. Ngokukodwa, i-hydrogen, njengesibaso esikhethwayo seeseli zamafutha, iya kuba nethemba lentengiso ebanzi kwindawo yezothutho kunye nokuveliswa kwamandla kwixesha elizayo, kwaye iya kuhlala kwindawo ebaluleke ngakumbi nangakumbi kulwakhiwo lwamandla lwexesha elizayo. Iindlela zemveli zokuvelisa i-hydrogen, ezifana nokuguqulwa komphunga we-hydrocarbon ukukhanya, i-electrolysis yamanzi, i-methanol cracking, i-gasification yamalahle kunye nokubola kwe-ammonia, zikhulile. Nangona kunjalo, kukho iingxaki "eziphezulu kunye nezimbini eziphantsi" ezifana neendleko eziphezulu, isivuno esiphantsi kunye nokusebenza kakuhle kwabasebenzi. Kwinkqubo yokuveliswa kweoli kunye negesi e-Liaohe Oilfield, kukho izibonelelo ze-hydrocarbon ezifana negesi eyomileyo kunye ne-naphtha. Ukusebenzisa le ndlela ukuvelisa i-hydrogen kunokwandisa ukusetyenziswa kobutyebi. Ngaphezu koko, icandelo eliphambili legesi yendalo ehambelanayo yi-methane, enokuthi iguqulwe ibe yi-hydrogen nge-hydrocarbon steam, ngokucoceka okuphezulu kwemveliso kunye nokusebenza kakuhle kwemveliso.

Umgaqo-nkqubo wemveliso ye-hydrogen ukusuka kwigesi yendalo

Iinkqubo eziphambili zokusetyenzwa kwegesi yendalo ziquka i-atmospheric kunye ne-vacuum distillation, i-catalytic cracking, i-catalytic reforming kunye nemveliso yearomatics. Ngexesha elifanayo, kubandakanya ukusetyenziswa kwegesi yendalo, ukuqokelela kunye nokuhanjiswa kunye nokucoca. Ngaphantsi koxinzelelo oluthile, ubushushu obuphezulu kunye ne-catalyst, i-alkanes kunye ne-steam kwigesi yendalo zisabela ngokwekhemikhali. I-gas yokuguqula ingena kwisiguquli emva kokutshintshwa kobushushu kwibhoyili ukuguqula i-CO ibe yi-H2 kunye ne-CO2. Emva kokutshintshiselana kobushushu, i-condensation kunye nokwahlukana kwamanzi omphunga, igesi idlula ngokulandelelana kwinqaba ye-adsorption exhotywe ngee-adsorbents ezithathu ngolawulo lwenkqubo, kwaye i-N2, i-Co, i-CH4 kunye ne-CO2 ixinzelelwe kwaye idsorbed ngoxinzelelo lwe-swing adsorption (PSA) ukukhupha imveliso. ihydrogen. Uhlalutyo lwe-depressurization lukhupha ukungcola kwaye luvuselele i-adsorbent

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