Sanin coke na man petroleum da calcined petroleum coke
1. Petroleum coke
Coke man fetur baƙar fata ne ko launin toka mai launin toka mai kauri mai kauri mai ƙyalli kuma yana da ƙura.Abubuwan coke na man fetur sune hydrocarbons, wanda ya ƙunshi 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur da mahadi masu nauyi.
Coke Petroleum wani samfur ne na pyrolysis na man feedstock a cikin jinkirin coking raka'a a babban yanayin zafi don samar da kayan mai mai haske.Abubuwan da ake samu na man coke kusan 25-30% na ɗanyen mai.Ƙimar ƙarancin calorific ɗinsa shine kusan sau 1.5-2 na kwal, abun cikin ash bai wuce 0.5% ba, al'amarin mara ƙarfi shine kusan 11%, kuma ingancin yana kusa da anthracite.
2. Matsayin ingancin man coke
Delayed petroleum coke yana nufin koren coke ɗin da aka samar da jinkirin coking unit, wanda kuma aka sani da coke na yau da kullun, kuma babu daidaitattun ma'auni na ƙasa a halin yanzu.A halin yanzu, kamfanonin samar da kayayyaki na cikin gida galibi suna samarwa ne bisa ga ka'idojin masana'antu SH0527-92 wanda tsohon Kamfanin Sinopec ya kirkira.An rarraba ma'auni musamman bisa ga abun ciki na sulfur na man coke.Daga cikin su, coke na farko da kuma No. 1 coke sun dace don yin lantarki na graphite na yau da kullun a cikin masana'antar sarrafa ƙarfe, kuma sun dace da carbon carbon a cikin masana'antar yin aluminum;Ana amfani da Coke No. 2 a cikin masana'antar yin aluminum.Electrode manna amfani da electrolytic Kwayoyin (tanderu) da kuma samar da graphite lantarki, No. 3 coke da ake amfani da samar da silicon carbide (abrasive abu) da kuma alli carbide (calcium carbide), da kuma sauran carbon kayayyakin, kuma amfani a yi na masana'antu. anodes ga aluminum smelting Kwayoyin Kasa block kuma amfani da fashewa tanderu carbon rufi tubali ko makera kasa yi.
3. Babban amfani da man fetur coke
Babban amfani da man coke ne pre-gasa anodes da anode pastes amfani da electrolytic aluminum, carbon masana'antu samar carbon enhancers, graphite lantarki, smelting masana'antu silicon, da kuma habaka.
Dangane da tsari da bayyanar coke na man fetur, samfuran coke na man fetur za a iya raba su zuwa nau'ikan 4: coke coke, coke soso, coke coke da foda: (1) coke coke, tare da tsari mai siffar allura da fiber, galibi ana amfani dashi. don steelmaking High-ikon graphite lantarki lantarki da matsananci-high-ikon graphite lantarki a Tun allura coke yana da m ingancin index bukatun cikin sharuddan sulfur abun ciki, ash abun ciki, maras tabbas al'amarin da gaskiya yawa, akwai musamman bukatun ga allura coke samar da fasaha da kuma raw. kayan aiki.
