Umusaruro wa hydrogen: Kuvugurura gazi karemano

Ivugurura rya gazi karemano ninzira yiterambere kandi ikuze yubakiye kubikorwa remezo byo gutanga imiyoboro isanzwe. Ninzira yingenzi yikoranabuhanga inzira yigihe gitoumusaruro wa hydrogen.

Bikora gute?

Kuvugurura gazi karemano, bizwi kandi kuvugurura methane (SMR), ni uburyo bukoreshwa cyane mu gukora hydrogen. Harimo reaction ya gaze naturel (cyane cyane metani) hamwe na parike munsi yumuvuduko mwinshi kandi imbere ya catalizator, ubusanzwe ishingiye kuri nikel, kugirango ikore uruvange rwa hydrogène, monoxyde de carbone, na dioxyde de carbone. Inzira igizwe n'intambwe ebyiri z'ingenzi:

Ivugurura rya Steam-Methane. Iyi ni inzira ya endothermic, bivuze ko isaba kwinjiza ubushyuhe.

CH4 + H2O (+ ubushyuhe) → CO + 3H2

Guhindura Amazi-Gazi (WGS): Monoxide ya karubone ikorwa muri SMR ikora hamwe na parike nyinshi kugirango ikore karuboni ya dioxyde na hydrogène yiyongera. Iyi ni exothermic reaction, irekura ubushyuhe.

CO + H2O → CO2 + H2 (+ ubushyuhe buke)

Nyuma yibi bitekerezo, gaze ivanze, izwi nka synthesis gaze cyangwa syngas, itunganywa kugirango ikureho dioxyde de carbone nindi myanda. Isuku rya hydrogène isanzwe igerwaho binyuzeigitutu swing adsorption(PSA), itandukanya hydrogène nizindi myuka ishingiye ku itandukaniro ryimyitwarire ya adsorption ihindagurika ryumuvuduko.

Kuki C.ingurubeUbu buryo?

Ikiguzi-Cyiza: Gazi karemano ni myinshi kandi ugereranije ihendutse, bigatuma SMR imwe muburyo buhendutse bwo gukora hydrogen.

Ibikorwa Remezo: Umuyoboro wa gazi usanzwe uhari utanga isoko ryuzuye ryibiryo, bikagabanya ibikenerwa remezo bishya.

Gukura:Ikoranabuhanga rya SMRirashinzwe neza kandi yakoreshejwe mumyaka mirongo mugukora hydrogène na syngas mubikorwa bitandukanye byinganda.

Ubunini: Ibimera bya SMR birashobora gupimwa kugirango bitange hydrogène mubwinshi bukwiranye nubunini buto kandi bunini.
