Soo jeedinta tignoolajiyada habka iyo sharraxaadda warshadda wax soo saarka haydarojiinta gaaska dabiiciga ah (1)
1) Jaantuska socodka habka aasaasiga ah ee soo saarista haydarojiin ee gaaska dabiiciga ah
Fiiro gaar ah: Sanduuqa dhibcaha leh waa aagga xadka ee Soo saarista haydarojiin qalab, iibiyuhuna wuxuu mas'uul ka yahay aagga ku jira sanduuqa dhibcaha leh.
2) Mabda'a Geedi socodka
Skid-ku-rakiban soo saarista haydarojiin ee gaaska dabiiciga ah Qalabka waxaa inta badan ka kooban yahay shan tallaabo oo muhiim ah oo habka ah: cadaadiska gaaska dabiiciga ah, nadiifinta gaaska dabiiciga ah ee ganaaxa, dib-u-habaynta uumiga gaaska dabiiciga ah, beddelka CO2, iyo kala-soocidda iyo nadiifinta haydarojiin.
1) Nadiifinta walxaha ceeriin ah
Gaaska dabiiciga ah ee cayriin waxaa lagu kululeeyaa 320-380℃ qaybta isku-xidhka ee dib-u-habeeynta ka dibna wuxuu dhex maraa manganese oxide iyo zinc oxide desulfurizers si looga saaro baaruudka dabiiciga ah iyo H.2S ee gaaska cayriin ku socota ka hooseeya 0.1ppm si loo daboolo shuruudaha sulfur ee kicinta dib-u-hagaajinta uumiga. Falcelinta ugu muhiimsan waa sidan soo socota:
H2S + ZnO→ ZnS + H2THE
2) Dib-u-habaynta uumiga gaaska dabiiciga ah: Ka dib marka sulfur-ka gaaska dabiiciga ah laga saaro meel ka hooseysa 0.1 PPm, waxaa lagu qasi karaa uumiga habka oo leh saamiga 3.2 ilaa 3.5, waxayna gashaa gariiradda isku dhafan ee horay u kululaynta gaaska si loogu sii kululeeyo 550 ilaa 600 °C ka hor inta aan la gelin tuubada dib-u-hagaajinta. Sariirta kicinta, methane waxay la falgashaa uumiga biyaha si ay u soo saarto H2 iyo CO, iyo CO waxay sii wadaan inay la falgalaan uumiga biyaha si ay u soo saaraan CO22. Kulaylka loo baahan yahay dib-u-habaynta methane waxaa bixiya gubashada gaaska isku dhafan ee shidaalka. Marka uu jiro kiciye nikkel ah, falcelintiisa ugu weyn waa sidan soo socota:
CH4 +H2O (uumi) = CO +3H2 -49200Kcal/Kmol (falcelinta beddelka)
CO+H2O (uumi) = CO2 +H2+9840Kcal/Kmol (falcelinta beddelka)
Falcelinta dildilaaca ee alkanes sare (400 ~ 600℃)
CnH2n + 2nH2O (uumi) =(2n+1) H2 + nCO
