Coke batroolku waa badeecad madow ama cawl madow oo adag oo batrool adag leh oo leh dhalaal macdan ah waana dalool.

Qaybaha kookaha batroolka waa hydrocarbons, oo ka kooban 90-97% kaarboon, 1.5-8% hydrogen, nitrogen, koloriin, baaruud iyo iskudhisyo bir culus ah.Coke batroolka waa wax-soo-saarka pyrolysis ee saliidda feedstock ee unugyo dib u dhigista heerkulka sare si loo soo saaro badeecooyinka saliidda fudud.Wax soo saarka kookaha batroolka waa qiyaastii 25-30% saliidda ceyriinka ah.Qiimaha kalooriga hooseeya wuxuu ku saabsan yahay 1.5-2 jeer ka dhuxusha, nuxurka dambasku kama badna 0.5%, arrinta kacsan waa qiyaastii 11%, tayada waxay ku dhowdahay anthracite.Marka loo eego qaab dhismeedka iyo muuqaalka coke batroolka, badeecada kookaha batroolka waxaa loo qaybin karaa 4 nooc: coke coke, coke sponge, coke projectile iyo coke budada ah:

(1) Irbada coke, oo leh qaab-dhismeedka irbad-u eg iyo texture fiber, waxaa inta badan loo isticmaalaa sida korantada garaafyada ultra-sare leh ee samaynta birta.Maadaama kookaha cirbadaha uu leeyahay shuruudaha index tayo adag oo ku saabsan maadada baaruudda, nuxurka dambaska, walxaha kacsan iyo cufnaanta dhabta ah, waxaa jira shuruudo gaar ah oo loogu talagalay tignoolajiyada wax soo saarka coke-ga iyo alaabta ceeriin.

(2) Coke isbuunyo, oo leh fal-celin kiimiko oo sarreeya iyo ka kooban wasakh yar, waxaa inta badan loo adeegsadaa warshadaha dhalada aluminium iyo warshadaha kaarboon.

(3) Coke Projectile ama kookaha wareegsan: Waa qaab wareegsan iyo dhexroor 0.6-30mm.Guud ahaan waxaa laga soo saaraa saliid sare-sare iyo saliid sare-asphaltene waxaana loo isticmaali karaa oo kaliya sida shidaalka warshadaha sida korontada iyo sibidhka.

(4) Coke budada ah: Waxaa lagu soo saaraa habka loo yaqaan 'coking coking', oo leh qaybo ganaax ah (0.1-0.4mm dhexroor), maaddo kacsan oo sarreeya iyo kororka fidinta kuleylka sare, sidaas darteed si toos ah looguma isticmaali karo diyaarinta korantada iyo warshadaha kaarboon.

Marka loo eego maadada baaruudda ee kala duwan, waxaa loo qaybin karaa kookaha baaruudda sare ah (kooxaha baaruudda ka sarreeya 3%) iyo kookaha baaruudda hoose (kooxaha baaruudda ka hooseeya 3%).Kookaha baaruudda-hooseeya waxaa loo isticmaali karaa sida koollada anode-ga iyo anodes-ka hore loo dubay ee dhirta aluminiumka iyo sida korantada graphite ee dhirta birta ah.Waxaa ka mid ah, kookaha-sulfur-yar oo tayo sare leh (koox ka kooban baaruud wax ka yar 0.5%) ayaa loo isticmaali karaa in lagu soo saaro koronto-garaafyada iyo kaarboonka.Koodhka baaruudda hooseeya ee tayada guud (in ka yar 1.5% baaruud) ayaa inta badan loo isticmaalaa si loo soo saaro anodes prebaked.Coke batroolka tayadiisu hooseyso waxaa inta badan loo isticmaalaa dhalaalinta silikoonka warshadaha iyo soo saarista koollada anode-ga.Coke-sulfur-sare ayaa guud ahaan loo isticmaalaa shidaal ahaan dhirta sibidhka iyo dhirta tamarta.

Coke batroolka Calcined:

Marka laga hadlayo electrodes graphite ee birta samaynta ama koollada anode-ka (dhalaalaya electrodes) ee aluminium iyo soosaarka magnesium, si loo waafajiyo kookaha batroolka (coke cagaaran) shuruudaha, kookaha cagaaran waa in la dhalaaliyaa.Heerkulka calcination guud ahaan waa ku dhawaad ​​1300 ° C, ujeedadu waa in meesha laga saaro qaybaha kacsan ee kookaha batroolka intii suurtagal ah.Sidan oo kale, waxa ku jira hydrogen-ka kookaha batroolka ee dib loo warshadeeyey waa la yarayn karaa, waxaana la wanaajin karaa heerka garaafka ee kookaha batroolka, taas oo kor u qaadeysa xoogga heerkulka sare iyo caabbinta kulaylka graphite-ka, iyo hagaajinta korantada garaafiga. electrode.Coke Calcined waxaa inta badan loo isticmaalaa in wax soo saarka ee electrodes graphite, alaabta koollada carbon, ciid dheeman, warshadaha fosfooraska heerka cuntada, warshadaha biraha iyo carbide calcium, ka mid ah kuwaas oo electrodes graphite yihiin kuwa ugu ballaaran loo isticmaalo.Coke-ka cagaaran waxaa si toos ah loogu isticmaali karaa kaarbiid-ka kaalshiyamka oo ah maadada ugu muhiimsan ee kaarbiid-ka-calciumka iyada oo aan lahayn calcination, iyo in la soo saaro silikoon carbide iyo boron carbide sida walxo abrasive ah.Waxa kale oo si toos ah loogu isticmaali karaa sida kookaha foornada qaraxa ee warshadaha birta ah ama leben kaarboon oo loogu talagalay dahaarka foornada qarxinta, waxaana sidoo kale loo isticmaali karaa sidii kookaha cufan ee habka shubista.
