Igitekerezo cy'ikoranabuhanga mu mikorere n'ibisobanuro by'uruganda rukora imyuka ya hydrogen (1)

1) Imbonerahamwe y'ibanze y'imigendekere y'ibikorwa ikorwa rya hydrogen ikomoka ku gaze karemano

Icyitonderwa: Agasanduku k'utudomo ni agace k'umupaka wa ikorwa rya hydrogen igikoresho, kandi umugurisha ni we ushinzwe agace kari mu gasanduku karimo utudomo.

2) Ihame ry'Inzira

Ifite sketi ikorwa rya hydrogen ikomoka ku gaze karemano Ibikoresho bikubiyemo ahanini intambwe eshanu z'ingenzi: gushyira umwuka mu kirere, gukuraho gazi karemano mu kirere, kuvugurura umwuka w'umwuka karemano, guhindura CO, no gutandukanya no gutunganya hydrogen.

1) Gukuraho sulfure mu bikoresho fatizo

Gazi karemano ishyushye kugeza kuri 320-380℃ mu gice cyo gushyushya cy'umuvuduko hanyuma ikanyura muri okiside ya manganese na zinc oxide desulfurizers kugira ngo ikuremo sulfur organic na H₂S muri gaze mbisi _kuri munsi ya 0.1ppm kugira ngo huzuzwe ibisabwa na sulfur bya catalyst ihindura umwuka. Ibyibandwaho by'ingenzi ni ibi bikurikira:

H₂S +ZnO→ ZnS + H₂IKI

2) Guhindura umwuka w’umwuka karemano: Nyuma yuko sulfure y’umwuka karemano ikurwaho ikagera munsi ya 0.1 PPm, ivangwa n’umwuka w’umwuka ku gipimo cya 3.2 kugeza 3.5, hanyuma ikinjira mu gikoresho cyo gushyushya umwuka uvanze kugira ngo yongere ishyushye kugeza kuri 550 kugeza kuri 600 °C mbere yo kwinjira mu muyoboro uhindura. Mu gice cy’umuyoboro, methane ikorana n’umwuka w’amazi kugira ngo ikore H₂ na CO, kandi CO ikomeje gukorana n'umwuka w'amazi kugira ngo itange CO_2. Ubushyuhe bukenewe kugira ngo metani ivugururwe butangwa no gutwika gaze ivanze na lisansi. Iyo hari catalyst ya nikeli, ingaruka zayo z'ingenzi ni izi zikurikira:

CH₄ +H₂O (umwuka) = CO +3H₂ -49200Kcal/Kmol (uburyo bwo guhindura)

CO+H₂O (umwuka) = CO₂ +H₂+9840Kcal/Kmol (uburyo bwo guhindura)

Uburyo bwo gucika kw'ibinure byo hejuru (400～600℃)

CnH₂n + 2nH₂O (umwuka) =(2n+1) H₂ + nCO
