Chinhu chinonyanya kukosha che adiabatic kushandurwa kwegasi rechisikigo kuita hydrogenNdekuti maitiro mazhinji ekugadzira zvinhu zvisina kugadzirwa anowanzova maitiro ekugadzira oxidation zvishoma, uye danho rekudzora kumhanya rave kukurumidza kuita oxidation zvishoma, izvo zvinovandudza zvikuru kugona kwekugadzira kweyuniti yekugadzira hydrogen yegesi rechisikigo. Maitiro ekugadzira hydrogen yekushandura gasi rechisikigo anoshandisa mhepo yakachipa senzvimbo yeokisijeni. Iyo reactor yakagadzirwa ine okisijeni inogona kugadzirisa dambudziko re catalyst bed uye kugoverwa kwesimba zvine mwero. Kugadzikana kwe reaction yezvinhu zvinokonzeresa kunovandudzwa zvakanyanya nekuda kwekudzikira kwenzvimbo inopisa pamubhedha. Kugadzirwa kwehydrogen diki panzvimbo yegasi rechisikigo kugadzirwa kwehydrogen yekushandura adiabatic panzvimbo yehydrogenation kunogona kuratidza zviri nani kugona kwayo kwakasimba kwekugadzira. Maitiro matsva aya ane mabhenefiti ekuita kwenguva pfupi uye nyore kushanda, uye anogona kuderedza zvakanyanya mari yekudyara uye yekugadzirwa kwehydrogen yeyuniti yekugadzira hydrogen diki panzvimbo yekuvaka.
Kuoxidation kwegasi rechisikigo kuita hydrogen. Zvichienzaniswa nenzira yechinyakare yekushandura steam, kuoxidation kwegasi rechisikigo kuita hydrogen kunodya simba shoma uye kunoshandisa refractory yakachipa zvikuru kurongedza reactor. Zvisinei, kuoxidation kwegasi rechisikigo kuita hydrogen kunowedzera mari inodhura yekudyara uye mutengo wekugadzira oxygen wechikamu chekuparadzanisa mhepo nekuda kwehuwandu hwakawanda hweoxygen yakachena. Kamudzira kanopenya ke ceramic inorganic oxygen kanoshandiswa se reactor ye catalytic partial oxidation yegasi rechisikigo, uye kugadzirwa kweokisijeni yakachipa kwakabatanidzwa ne catalytic partial oxidation yegasi rechisikigo kuita hydrogen panguva imwe chete. Mhedzisiro yekutanga yekuongorora kwehunyanzvi nehupfumi inoratidza kuti kana tichienzanisa nemaitiro ekugadzira, mari yechikamu ichaderedzwa neinenge 25-30% uye mutengo wekugadzira uchaderedzwa ne30-50%.
Kupwanyika kwegasi rechisikigo pakupisa kwakanyanya kuti rigadzire hydrogen. Kugadzirwa kwehydrogen kubva ku pyrolysis yegasi rechisikigo ndiko kupwanyika kwegasi rechisikigo kuita hydrogen nekabhoni pakupisa kwakanyanya. Maitiro aya anoonekwa senzira yekuchinja pakati pemafuta efossil nesimba rinogona kushandiswazve nekuti hariburitse kabhoni dhayokisaidhi. Liaohe Oilfield yakaita tsvakurudzo yakawanda pamusoro pekubvisa hydrogen kubva pakupisa kwakanyanya. Kabhoni inogadzirwa inogona kuva nekushandiswa kwakakosha uye mikana yakakura yemusika.
Kugadzirwa kwehydrogen kuburikidza ne autothermal reforming yegasi rechisikigo. Kana tichienzanisa nemaitiro ekugadzirisa, maitiro acho anoshandura kupisa kwekunze kuita kuzvidziisa, uye kushandiswa kwe reaction heat kuri nani. Nheyo ndeyekuti exothermic natural gas combustion reaction uye strong endothermic natural gas steam reforming reaction zvakabatana mu reactor, uye reaction system pachayo inogona kuzvidziisa. Pamusoro pezvo, sezvo strong exothermic reaction uye strong endothermic reaction mu autothermal reforming reactor zvichiitwa nhanho nhanho, reactor ichiri kuda pombi yesimbi isina ngura inodziya zvakanyanya se reactor, izvo zvinoita kuti natural gas autothermal reforming reaction process ive nedambudziko rekudyara mari yakawanda uye kugona kushoma kwekugadzira.
