| Sifada: | Waxay leedahay awood kulayl sare (δb≥440MPa) iyo iska caabbinta oksaydhka heerkulka sare, waxayna leedahay iska caabin gaar ah oo ay u leedahay daxalka hydrogen. Isku-dhafka balaarinta kulaylku waa yar yahay, korantada kulaylku waa sarreeyaa, waxqabadka geeddi-socodku waa wanaagsan yahay, heerkulku waa 450-620 darajo Celsius, jilicsanaanta qallafsanaanta birta waa caddahay, alxanka ayaa liita. Waxaa si weyn loogu isticmaalaa soo saarida marawaxadaha uumiga iyo kuleyliyaha, waxaana inta badan loo adeegsadaa tuubooyinka kulaylka iyo kuwa kulaylka badan iyo weelasha cadaadiska sare leh. | Waxay leedahay iska caabin oksaydh oo wanaagsan agagaarka 650 darajo Celsius, kulayl wanaagsan oo ka hooseeya 600, nuugista shoogga wanaagsan iyo kulaylka kuleylka, waxaana si weyn loogu isticmaalaa marawaxadaha uumiga. Si kastaba ha ahaatee, nooca birta ah ayaa leh u janjeera weyn si ay u adkaato oo ay leedahay waxqabadka alxanka oo liita. Waxay leedahay sifooyin farsamo heerkul sare oo wanaagsan, xasilloonida qaab-dhismeed yar, caabbinta daxalka, iyo adkaanta wanaagsan. Si ballaaran loogu isticmaalo batroolka, beddelidda dhuxusha, tamarta nukliyeerka, xannibaadda marawaxadaha uumiga, kuleyliyaha tamarta kulaylka iyo xaaladaha kale ee adag ee shaqada, jawiga warbaahinta daxalka ah. | ||
| Codsiga: | Batroolka, kiimikaad kiimikaad, kuleyliyaha cadaadiska sare leh, iyo tubooyinka kale ee ujeeddo gaar ah waxaa ka mid ah tuubooyinka kuleyliyaha, tuubooyinka birta ah ee juqraafiyeed, iyo tuubooyinka batroolka ee aan xirneyn. Tuubooyinka iyo foornada waxaa loo isticmaali karaa weelasha cadaadiska. Tubooyinka uumiga iyo madaxyada leh heerkulka gidaarka ≤510 ℃; Kuleylinta tuubada dusha sare leh heerkulka gidaarka ≤540 ℃. | Daxalka baaruudda heerkulka sarreeya, heerkulka sare ee hydrogen iyo daxalka hydrogen sulfide, daxalka acid organic. Tuubada dib u kululaynta oo leh heerkul gidaar 630 ℃ -650 ℃. Tuubooyinka iyo foornada waxaa loo isticmaali karaa weelasha cadaadiska. Daxalka baaruudda heerkulka sare, heerkulka sare ee hydrogen iyo hydrogen sulfide daxalka, daxalka acid organic. Tuubada dib u kululaynta oo leh heerkul gidaar 630 ℃ -650 ℃. | ||
