Raws li kev lag luam tshawb fawb lub koom haum cov ntaub ntawv,natural gas hydrogen ntau lawmtxheej txheem tam sim no occupies thawj qhov chaw nyob rau hauv lub ntiaj teb no hydrogen ntau lawm ua lag luam. Qhov kev faib ua feem ntawm hydrogen ntau lawm los ntawm natural gas nyob rau hauv Tuam Tshoj nyob rau theem thib ob, tom qab ntawd los ntawm thee. Hydrogen ntau lawm los ntawm natural gas nyob rau hauv Tuam Tshoj pib nyob rau hauv 1970s, feem ntau muab hydrogen rau ammonia synthesis. Nrog rau kev txhim kho cov catalyst zoo, cov txheej txheem ntws, tswj theem, cov khoom siv thiab cov qauv kev ua kom zoo, kev ntseeg tau thiab kev nyab xeeb ntawm cov txheej txheem ntawm cov roj hydrogen ntau lawm tau lav.
Natural gas hydrogen txheej txheem feem ntau muaj xws li plaub kauj ruam: raw gas pretreatment, natural gas steam reforming, carbon monoxide hloov,hydrogen purification.
Thawj kauj ruam yog raw khoom pretreatment, uas feem ntau yog hais txog cov roj desulfurization, cov txheej txheem ua haujlwm tiag tiag feem ntau siv cobalt molybdenum hydrogenation series zinc oxide ua desulfurizer los hloov cov organic sulfur hauv cov pa roj rau hauv inorganic sulfur thiab tshem tawm nws.
Cov kauj ruam thib ob yog qhov kev hloov pauv ntawm cov pa roj carbon monoxide, uas siv cov nickel catalyst hauv kev hloov pauv hloov cov alkanes hauv cov pa roj rau hauv cov pa roj uas nws lub ntsiab yog carbon monoxide thiab hydrogen.
Qhov thib peb kauj ruam yog carbon monoxide hloov. Nws reacts nrog dej vapor nyob rau hauv lub xub ntiag ntawm ib tug catalyst, yog li tsim hydrogen thiab carbon dioxide, thiab tau txais ib tug hloov roj uas yog tsim los ntawm hydrogen thiab carbon dioxide.
Cov kauj ruam kawg yog ua kom huv si hydrogen, tam sim no feem ntau siv hydrogen purification system yog lub siab viav vias adsorption (PSA) purification cais system. Cov txheej txheem no muaj cov yam ntxwv ntawm kev siv hluav taws xob tsawg, cov txheej txheem yooj yim thiab siab purity ntawm hydrogen.
Hydrogen ntau lawm los ntawm cov nkev roj muaj qhov zoo ntawm qhov loj hydrogen ntau lawm teev thiab paub tab technology, thiab yog lub ntsiab ntawm hydrogen tam sim no. Txawm hais tias cov pa roj carbon monoxide tseem yog cov roj fossil thiab tsim cov pa roj hauv tsev cog khoom hauv kev tsim cov xiav hydrogen, tab sis vim yog siv cov thev naus laus zis xws li carbon capture, siv thiab cia (CCUS), nws tau txo qhov cuam tshuam rau lub ntiaj teb ib puag ncig los ntawm kev ntes. tsev cog khoom gases thiab ua tiav cov khoom tsim tawm qis.
