Kugadzirwa kweHydrogen: Kugadzirisa Gasi Rakasikwa

Kugadziridza gasi remusikirwo inzira yepamberi uye yakura yekugadzira inovaka pamusoro peiyo iripo gasi pombi yekuburitsa pombi. Iyi ndiyo yakakosha tekinoroji nzira yepedyo-nguvakugadzirwa kwehydrogen.

Inoshanda Sei?

Gasi rekugadzirisa, inozivikanwawo se steam methane reforming (SMR), inzira inoshandiswa zvakanyanya pakugadzirwa kwehydrogen. Inosanganisira kuita kwegasi rechisikigo (kunyanya methane) nemhepo iri pasi pekumanikidzwa kwakanyanya uye pamberi pechinokonzera, kazhinji nickel-based, kugadzira musanganiswa wehydrogen, carbon monoxide, uye carbon dioxide. Iyo nzira ine matanho makuru maviri:

Steam-Methane Reforming(SMR): Mabatiro ekutanga apo methane inobatwa nechiutsi kugadzira haidrojeni nekabhoni monoxide. Iyi ndiyo endothermic process, zvichireva kuti inoda kupinza kupisa.

CH4 + H2O (+ kupisa) → CO + 3H2

Mvura-Gasi Shift Reaction (WGS): Iyo kabhoni monoxide inogadzirwa muSMR inopindirana nehutsi hwakawanda kuumba kabhoni dhaidhirodhi uye imwe hydrogen. Uku ndiko kuita kunopisa, kuburitsa kupisa.

CO + H2O → CO2 + H2 (+ shoma shoma yekupisa)

Mushure mekuita uku, musanganiswa wegasi unozobuda, unozivikanwa sesynthesis gas kana syngas, unogadziriswa kubvisa kabhoni dhiabhorosi uye kumwe kusvibiswa. Kucheneswa kwehydrogen kunowanikwa kuburikidzapressure swing adsorption(PSA), iyo inoparadzanisa hydrogen kubva kune mamwe magasi zvichienderana nekusiyana kwemaitiro adsorption pasi pekumanikidza shanduko.

Nei ChooseThis Process?

Mutengo-Kushanda: Gasi remusikirwo rakawanda uye haridhure, zvichiita kuti SMR ive imwe yedzakanyanya kudhura nzira dzekugadzira haidrojeni.

Infrastructure: Iyo iripo gasi pombi pombi network inopa yakagadzirira kupihwa feedstock, ichideredza kudiwa kwezvivakwa zvitsva.

Kukura:SMR tekinorojiyakanyatsosimbiswa uye yakashandiswa kwemakumi emakore mukugadzirwa kwehydrogen uye syngas kune akasiyana maindasitiri ekushandisa.

Scalability: Zvidyarwa zveSMR zvinogona kuyerwa kuti zvibudise hydrogen muhuwandu hwakakodzera kune ese madiki-adiki uye makuru-makuro ekushandisa.
