(2) Sponge coke, nke nwere mmeghachi omume kemịkalụ dị elu yana ọdịnaya adịghị ọcha dị ala, bụ nke a na-ejikarị na ụlọ ọrụ na-agbaze aluminum na ụlọ ọrụ carbon.

(3) Coke projectile ma ọ bụ coke dị okirikiri: Ọ dị okirikiri n'ụdị yana dayameta 0.6-30mm.A na-emepụta ya site na nnukwu sọlfọ na nnukwu asphaltene mmanụ fọdụrụnụ ma nwee ike iji ya mee ihe dị ka mmanụ ọkụ ụlọ ọrụ dị ka ike na ciment.

(4) Powder coke: A na-emepụta ya site na usoro coking fluidized, nke nwere ihe dị mma (0.1-0.4mm na dayameta), ọdịnaya dị elu na-agbanwe agbanwe na ọnụ ọgụgụ dị elu nke okpomọkụ, n'ihi ya, a pụghị iji ya mee ihe ozugbo na nkwadebe electrode na ụlọ ọrụ carbon.

Dị ka ọdịnaya sọlfọ dị iche iche si dị, enwere ike kewaa ya na coke-sulfur dị elu (ọdịnaya sọlfọ dị n'elu 3%) na obere sọlfọ coke (ọdịnaya sọlfọ n'okpuru 3%).Enwere ike iji coke sọlfọ dị ala dị ka tapawa anode na anodes prebaked maka osisi aluminom yana dị ka electrodes graphite maka osisi nchara.N'ime ha, enwere ike iji coke obere sọlfọ dị elu (ọdịnaya sọlfọ na-erughị 0.5%) mepụta electrodes graphite na carbon enhancers.Coke sọlfọ dị ala nke ịdị mma n'ozuzu (ihe na-erughị 1.5% sọlfọ) na-ejikarị emepụta anodes prebaked.A na-ejikarị coke mmanụ ala dị ala eme ihe maka ịgbaze silicon ụlọ ọrụ na-emepụta mado anode.A na-ejikarị coke sọlfọ dị elu mee ihe dị ka mmanụ ọkụ na ụlọ ciment na ụlọ ọrụ ike.

Calcined Petroleum Coke:

N'ihe banyere electrodes graphite maka nchara ma ọ bụ ihe mgbochi anode (electrodes na-agbaze) maka mmepụta aluminum na magnesium, iji mee ka mmanụ ala coke (coke green) dị ka ihe ndị a chọrọ, a ghaghị ịmepụta coke green.Okpomọkụ calcination na-adịkarị gburugburu 1300 Celsius C, ebumnuche bụ iwepu ihe ndị na-agbanwe agbanwe nke coke mmanụ ala dịka o kwere mee.N'ụzọ dị otú a, enwere ike ibelata ọdịnaya hydrogen nke coke petroleum recycled, na enwere ike imeziwanye ogo graphitization nke coke mmanụ, si otú ahụ na-eme ka ike okpomọkụ dị elu na nguzogide okpomọkụ nke electrode graphite, na imeziwanye eletriki eletrik nke graphite. electrode.Calcined coke bụ tumadi eji na mmepụta nke graphite electrodes, carbon mado ngwaahịa, diamond ájá, nri-ọkwa site ụlọ ọrụ, metallurgical ụlọ ọrụ na calcium carbide, n'ime nke graphite electrodes na-kasị eji.Enwere ike iji koke na-acha akwụkwọ ndụ akwụkwọ ndụ ozugbo maka calcium carbide dị ka ihe bụ isi nke calcium carbide na-enweghị calcination, na ịmepụta silicon carbide na boron carbide dị ka ihe abrasive.Enwere ike iji ya ozugbo dị ka coke maka ọkụ ọkụ na ụlọ ọrụ ọla ma ọ bụ brik carbon maka mkpuchi mgbidi ọkụ ọkụ, a pụkwara iji ya dị ka nnukwu coke maka usoro nkedo.
