Kugadzirwa kwehydrogen negasi rechisikigo ine zvakanakira zvemutengo wakaderera uye mhedzisiro yakakura. Kutsvagurudza nekuvandudza tekinoroji itsva yepamusoro yekugadzira hydrogen kubva mugasi rechisikigo ivimbiso yakakosha yekugadzirisa dambudziko rehydrogen yakachipa. Sesimba repamusoro uye rakachena remaindasitiri, gasi rechisikigo rine zvinhu zvakakosha zvekugadzira simba muChina. Panguva imwe chete, ndirowo zvinhu zvekutanga zvezvigadzirwa zvemakemikari zvakawanda.
Sechigadzirwa chechipiri chemakemikari, hydrogen inoshandiswa zvakanyanya mumaindasitiri emishonga, makemikari akanaka, emagetsi uye emagetsi. Kunyanya, hydrogen, semafuta anodiwa emasero emafuta, ichave netariro yakakura yemusika mumunda wekufambisa uye kugadzira magetsi mune ramangwana uye ichave nenzvimbo yakakosha muchimiro chesimba remangwana. Nzira dzechinyakare dzekugadzira hydrogen, dzakadai sekushandura svutugadzike yehydrocarbon light, electrolysis yemvura, methanol cracking, coal gasification uye ammonia decomposition, dzakura zvishoma. Zvisinei, kune mamwe matambudziko, akadai semutengo wakakwira, mwero wakaderera wekubuda, kushanda kwakaderera kwevashandi, rimwe rakakwirira uye maviri rakaderera. Mukugadzirwa kwemafuta negasi muLiaohe Oilfield, kune zviwanikwa zvehydrocarbon zvakaita segasi rakaoma ne naphtha. Kugadzirwa kwehydrogen nenzira iyi kunogona kuwedzera kushandiswa kwezviwanikwa. Uyezve, chikamu chikuru chegasi rechisikigo rinobatanidzwa i methane, iyo inogona kushandurwa kuita hydrogen ne hydrocarbon steam, ine kuchena kwakanyanya kwekugadzirwa uye kushanda kwakawanda kwekugadzirwa.
Maitiro makuru ekugadzirisa gasi rechisikigo anosanganisira kunyungudutsa mumhepo ne vacuum, kupwanya macatalytic, kugadzirisa macatalytic uye kugadzirwa kwe aromatics. Panguva imwe chete, kusanganisira kushandiswa kwegasi rechisikigo, kuunganidzwa nekucheneswa, alkanes ne steam mugasi rechisikigo zvinosangana nemakemikari pasi pekumanikidzwa kwakati, kupisa kwakanyanya uye catalyst.
Mushure mekuchinjwa kwekupisa mubhaira remubhadharo, gasi rinoshandurwa rinopinda muchoto chekuchinja kuti rishandure Co kuita H2 neCO2. Zvadaro, mushure mekuchinjwa kwekupisa, kusanganiswa kwemvura uye kupatsanurwa kwemvura yeutsi, gasi rinopfuudzwa nenzira yakatevedzana nepakati peshongwe yekusvina ine adsorbents nhatu dzakatarwa kuburikidza nekudzora chirongwa, uye N2 co CH4 CO2 inomanikidzwa uye inonyungudutswa ne pressure swing adsorption (PSA) kuti ibudise hydrogen yechigadzirwa, kuderedza kushushikana uye kuongorora kuti ibudise tsvina uye igadzire adsorbent patsva.
