Kookaha batroolka waa batrool adag oo madow ama cawl madow ah oo leh dhalaal bir ah waana daloolo.

Qaybaha kookaha batroolka waa haydaro-haydaro, oo ka kooban 90-97% kaarboon, 1.5-8% haydarojiin, nitrojiin, koloriin, sulfur iyo isku-dhisyo bir culus. Kookaha batroolka waa wax soo saar ka soo baxa pyrolysis-ka saliidda quudinta ee cutubyada kookaha ee dib u dhacay heerkul sare si loo soo saaro badeecooyin saliid fudud ah. Wax soo saarka kookaha batroolka waa qiyaastii 25-30% saliidda cayriin. Qiimaha kalooriyadeed ee hooseeya waa qiyaastii 1.5-2 jeer ka badan dhuxusha, dambasku kama badna 0.5%, arrinta kacsan waa qiyaastii 11%, tayaduna waxay u dhowdahay anthracite. Sida laga soo xigtay qaab-dhismeedka iyo muuqaalka kookaha batroolka, badeecooyinka kookaha batroolka waxaa loo qaybin karaa 4 nooc: kookaha irbadda, kookaha isbuunyada, kookaha projectile iyo kookaha budada ah:

(1) Coke-ka irbadda, oo leh qaab-dhismeed irbad u eg iyo qaab-dhismeed fiber ah, waxaa inta badan loo isticmaalaa elektroodhada garaafka ee awoodda sare leh iyo kuwa aadka u sarreeya ee sameynta birta. Maadaama coke-ka irbadda uu leeyahay shuruudo tayo oo adag marka la eego maaddada sulfur, maaddada dambaska, walxaha isbeddela iyo cufnaanta dhabta ah, waxaa jira shuruudo gaar ah oo loogu talagalay tiknoolajiyada wax soo saarka coke-ka irbadda iyo walxaha ceeriin.

(2) Kookaha isbuunyada, oo leh falcelin kiimiko oo sareysa iyo wasakh yar, waxaa inta badan loo isticmaalaa warshadaha dhalaalinta aluminiumka iyo warshadaha kaarboonka.

(3) Kookaha matoorka leh ama kookaha wareegsan: Waa qaab wareegsan oo dhexroorkiisu yahay 0.6-30mm. Guud ahaan waxaa laga soo saaraa saliidda harsan ee sulfur sare leh iyo tan asphaltene sare leh waxaana loo isticmaali karaa oo keliya shidaal warshadeed sida koronto dhalinta iyo sibidhka.

(4) Kookaha budada ah: Waxaa lagu soo saaraa habka kookaynta dareeraha ah, oo leh walxo yaryar (dhexroorka 0.1-0.4mm), walxo badan oo kacsan iyo isku-darka ballaarinta kulaylka oo sarreeya, sidaa darteed si toos ah looguma isticmaali karo diyaarinta elektiroonigga iyo warshadaha kaarboonka.

Sida ku cad tirada kala duwan ee sulfur-ka, waxaa loo qaybin karaa kook sulfur sare leh (ka kooban sulfur ka badan 3%) iyo kook sulfur hooseeya (ka kooban sulfur ka hooseeya 3%). Kook sulfur hooseeya waxaa loo isticmaali karaa kook anode iyo anode hore loo dubay oo loogu talagalay dhirta aluminiumka iyo sidoo kale elektroodka garaafiga ee dhirta birta ah. Kuwaas waxaa ka mid ah, kook sulfur tayo sare leh (ka kooban sulfur ka yar 0.5%) ayaa loo isticmaali karaa in lagu soo saaro elektroodka garaafiga iyo kor u qaadida kaarboonka. Kook sulfur hooseeya oo tayo guud leh (ka yar 1.5% sulfur) ayaa badanaa loo isticmaalaa in lagu soo saaro anode hore loo dubay. Kook batrool tayo hoose leh waxaa inta badan loo isticmaalaa in lagu dhalaaliyo silikoon warshadeed iyo in la soo saaro kook anode. Kook sulfur sare leh guud ahaan waxaa loo isticmaalaa shidaal ahaan warshadaha sibidhka iyo warshadaha korontada.

Kookaha batroolka ee Calcined:

Marka laga hadlayo elektroodka graphite ee sameynta birta ama balaastigga anode (elektroodka dhalaalaya) ee wax soo saarka aluminiumka iyo magnesium, si loogu waafajiyo kookaha batroolka (kookaha cagaaran) shuruudaha, kookaha cagaaran waa in la kabaa. Heerkulka kalkuleyntu guud ahaan waa qiyaastii 1300 ° C, ujeedadu waa in laga saaro qaybaha isbedbeddela ee kookaha batroolka intii suurtagal ah. Sidan, waxaa la dhimi karaa heerka haydarojiinta ee kookaha batroolka ee dib loo warshadeeyay, heerka garaafka ee kookaha batroolkana waa la hagaajin karaa, taasoo hagaajinaysa xoogga heerkulka sare iyo iska caabbinta kulaylka ee kookaha graphite, iyo hagaajinta socodka korontada ee kookaha graphite. Kookaha la kabaatisiyay waxaa inta badan loo isticmaalaa soo saarista elektroodka graphite, alaabada kookaha kaarboonka, ciidda dheemanka, warshadaha fosfooraska heerka cuntada, warshadaha birta iyo kaalshiyamka kaarbiyamka, kuwaas oo elektroodka graphite ay yihiin kuwa ugu badan ee la isticmaalo. Kookaha cagaaran waxaa si toos ah loogu isticmaali karaa kaalshiyamka kaarbiyamka iyadoo ah walaxda ugu weyn ee kaalshiyamka kaarbiyamka iyada oo aan la kabaatisayn, iyo in la soo saaro kaarbiyamka silikoon iyo kaarbiyamka boron sida walxaha xoqa. Waxa kale oo si toos ah loogu isticmaali karaa sida coke foornada qaraxa ee warshadaha birta ama leben kaarboon loogu talagalay dahaarka derbiga foornada qaraxa, waxaana sidoo kale loo isticmaali karaa sida coke cufan ee habka shubka.
