Ọmụma nke petroleum coke na calcined petroleum coke
1. Petroleum koke
Coke mmanụ ala bụ ngwaahịa mmanụ ala siri ike siri ike nke ojii ma ọ bụ isi awọ gbara ọchịchịrị nwere ọmarịcha ọla ma nwee oghere.Ihe mejupụtara coke mmanụ bụ hydrocarbons, nwere 90-97% carbon, 1.5-8% hydrogen, nitrogen, chlorine, sọlfọ na ogige ọla dị arọ.
Coke mmanụ ala bụ ngwaahịa sitere na pyrolysis nke mmanụ nri na ngalaba coking na-egbu oge na oke okpomọkụ iji mepụta ngwaahịa mmanụ ọkụ.Nsonaazụ nke coke mmanụ ala bụ ihe dịka 25-30% nke mmanụ raw.Uru calorific ya dị ala bụ ihe dịka 1.5-2 ugboro nke coal, ọdịnaya ash adịghị karịa 0.5%, ihe na-agbanwe agbanwe bụ ihe dịka 11%, na àgwà dị nso na anthracite.
2. Ụkpụrụ dị mma nke coke mmanụ ala
Coke mmanụ ala na-egbu oge na-ezo aka na coke akwụkwọ ndụ akwụkwọ ndụ nke ngalaba coking na-egbu oge na-emepụta, nke a makwaara dị ka coke nkịtị, na enweghị ọkọlọtọ mba kwekọrọ ugbu a.Ka ọ dị ugbu a, ụlọ ọrụ mmepụta ụlọ na-emepụtakarị dịka ọkọlọtọ ụlọ ọrụ SH0527-92 nke ụlọ ọrụ Sinopec mbụ chepụtara.A na-ekewa ọkọlọtọ ahụ dịka ọdịnaya sọlfọ nke coke mmanụ ala siri dị.N'ime ha, nke mbụ-ọkwa coke na No. 1 coke na-adabara na-eme ka nkịtị ike graphite electrodes na steelmaking ụlọ ọrụ, na-adabara maka aluminum carbon na aluminum eme ụlọ ọrụ;A na-eji No. 2 coke eme ihe na ụlọ ọrụ na-emepụta aluminum.Electrode tapawa eji na electrolytic cell (ọkụ) na mmepụta nke graphite electrodes, Nke 3 coke na-eji maka mmepụta nke silicon carbide (abrasive ihe) na calcium carbide (calcium carbide), na ndị ọzọ carbon ngwaahịa, na-eji na mmepụta nke anodes maka aluminom sel na-agbaze n'ala ngọngọ na-eji maka mgbawa ọkụ carbon lining brik ma ọ bụ ọkụ na-ewu ala.
3. Isi ojiji nke petroleum coke
Isi ojiji nke coke mmanụ ala bụ anodes na-ebu ụzọ bute na pastes anode ejiri na aluminom electrolytic, carbon ụlọ ọrụ mmepụta carbon enhancers, graphite electrodes, smelting ụlọ ọrụ silicon, na mmanụ ụgbọala.
Dabere na nhazi na ọdịdị nke coke mmanụ ala, ngwaahịa coke mmanụ nwere ike kewaa n'ụdị 4: coke coke, sponge coke, projectile coke na powder coke: (1) coke coke, nke nwere usoro agịga doro anya na eriri eriri, nke a na-ejikarị eme ihe. maka steelmaking High-power graphite electrodes na ultra-high-power graphite electrodes in Ebe ọ bụ na coke agịga nwere nlezianya dị mma index chọrọ n'ihe gbasara ọdịnaya sọlfọ, ọdịnaya ash, ihe na-agbanwe agbanwe na ezigbo njupụta, enwere ihe pụrụ iche chọrọ maka teknụzụ mmepụta coke na raw. ihe.
(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 ọnụọgụ mgbasawanye ọkụ dị elu, a pụghịkwa iji ya mee ihe ozugbo na nkwadebe electrode na ụlọ ọrụ carbon.
