Coke man fetur baki ne ko launin toka mai launin toka mai kauri mai kauri mai kauri kuma yana da kyalli.Abu ne na granular, columnar, ko allura-kamar carbonaceous abu wanda ya ƙunshi lu'ulu'u masu hoto na faifai.
Coke man fetur ya ƙunshi hydrocarbons, 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sulfur, da mahadi masu nauyi.
Coke Petroleum shine samfurin pyrolysis na danyen mai a cikin jinkirin coking naúrar don samar da mai mai haske a matsanancin zafi.
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, abun ciki mara ƙarfi shine kusan 11%, kuma ingancinsa yana kusa da anthracite.
2:Kyakkyawan mizanin coke na man fetur Delayed petroleum coke yana nufin coke da aka samu ta hanyar jinkirin coking unit, wanda kuma aka sani da talakawa coke, babu daidaitattun ##.
A halin yanzu, kamfanonin samar da kayayyaki na cikin gida galibi suna samar da su ne bisa ga ma'aunin masana'antu SH0527-92 da tsohuwar Kamfanin Petrochemical na kasar Sin ya tsara.
An rarraba ma'auni musamman bisa ga abun ciki na sulfur na man coke.
No. 1 Coke ya dace da yin talakawa ikon graphite lantarki a steelmaking masana'antu, da kuma amfani da matsayin carbon ga aluminum refining.
No. 2 coke da ake amfani da electrode manna da graphite electrode samar a electrolytic cell (tanderu) a aluminum smelting masana'antu.
Ana amfani da Coke No. 3 a cikin samar da silicon carbide (kayan niƙa) da calcium carbide (calcium carbide), da sauran kayayyakin carbon, da kuma a cikin samar da anode tubalan ga aluminum smelter da kuma gina carbon rufi. tubali ko makera kasa a cikin tanderun fashewa.
3: babban AMFANIN mai coke
Babban USES na man fetur coke ne pre-gasa anode da anode manna ga electrolytic aluminum, carbon samar da carbonizing wakili, graphite lantarki, smelting masana'antu silicon da man fetur, da dai sauransu.
Dangane da tsari da bayyanar coke na man fetur, ana iya raba samfuran coke na man fetur zuwa coke coke, soso coke, projectile coke da coke foda:
(1) Coke mai siffar allura, tare da tsari mai kama da allura da nau'in fiber, galibi ana amfani da shi azaman lantarki mai ƙarfi graphite da lantarki mai ƙarfi mai ƙarfi a cikin ƙarfe.
Saboda coke na allura yana da ƙayyadaddun buƙatun ƙididdiga masu inganci a cikin abun ciki na sulfur, abun cikin ash, abun ciki mara ƙarfi da yawa na gaskiya, akwai buƙatu na musamman akan fasahar samarwa da albarkatun ƙasa na coke coke.
(2) Soso coke, tare da high sinadaran reactivity da low kazanta abun ciki, yafi amfani a aluminum smelting masana'antu da carbon masana'antu.
(3) Coke Projectile ko mai siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar .Gabaɗaya ana samar da shi ne daga babban sulfur da ragowar asphaltene kuma ana iya amfani da shi kawai don samar da wutar lantarki, siminti da sauran albarkatun masana'antu.
(4) Powder coke: ana samar da shi ta hanyar aiwatar da coking mai ruwa tare da ƙananan barbashi (diamita: 0.1-0.4mm), babban abun ciki na volatilization da babban haɓakar haɓakar thermal, don haka ba za a iya amfani da shi kai tsaye a cikin shirye-shiryen lantarki da masana'antar carbon ba.
4: Calcined Petroleum Coke
Lokacin da graphite lantarki don yin karfe ko manna anode (narkewar lantarki) na aluminum da magnesium, don yin coke na man fetur (coke) ya dace da buƙatun, coke dole ne a calcined.
A calcining zafin jiki ne gaba ɗaya a kusa da 1300 ℃, dalilin da ya sa shi ne don kawar da naphthol coke volatilization har zuwa yiwu.
Ta wannan hanyar, za a iya rage yawan abubuwan da ke cikin hydrogen na man coke reproducts, za a iya inganta digiri na graphitization na man coke, za a iya inganta ƙarfin zafin jiki da ƙarfin zafi na graphite electrode, kuma za'a iya inganta halayen lantarki na graphite electrode. .
Calcining yafi amfani don samar da graphite lantarki, carbon manna kayayyakin, Diamond yashi, abinci-sa phosphorus masana'antu, karfe masana'antu da kuma calcium carbide, daga cikinsu graphite lantarki ne yadu amfani.
Ana iya amfani da Coke ba tare da ƙirƙira kai tsaye azaman calcium carbide, silicon carbide da boron carbide azaman kayan niƙa ba.
Hakanan za'a iya amfani dashi kai tsaye azaman coke don murhun masana'antar fashewar ƙarfe ko fashewar tanderun rufin tubalin carbon, Hakanan za'a iya amfani dashi don aiwatar da ƙaramin coke mai ƙarfi, da sauransu.
