Carbon Mai Aiki - Samarwa da Siffofin Samfura

Kayan aikin farko na samar da Carbon mai aiki sune: kayan da ke ɗauke da carbon kamar itace, peat, lignite, kwal mai tauri, ƙwayoyin 'ya'yan itace kamar ramin zaitun, Kwakwa Shell , da sauransu. Ana iya aiwatar da kunna waɗannan kayan ta amfani da hanyoyi guda biyu daban-daban.

A cikin kunna iskar gas, ana amfani da kayan da aka riga aka yi amfani da su wajen samar da iskar gas kuma ana fallasa su ga tasirin iskar gas, kamar tururin ruwa, carbon dioxide, iska, ko gaurayawan su. Zafin kunnawa yana da kusan 700–1000°C, inda carbon ɗin ke ƙonewa kaɗan bayan amsawar ruwa da iskar gas, don haka yana ƙirƙirar kwarangwal mai ramuka masu aiki sosai.

A lokacin kunna sinadarai, yawanci ana haɗa abu mara carbon, mai ɗauke da carbon tare da sinadarai masu bushewa da kuma oxidizing. Sannan ana dumama cakuda da aka samu zuwa 400–800°C. Ana wanke sinadaran kunnawa - waɗanda zasu iya haɗawa da zinc chloride, phosphoric acid, sulfuric acid, da sauransu - daga baya ana wanke su sannan a dawo da su.
