Ulwazi lwe-petroleum coke kanye ne-calcined petroleum coke
1. I-petroleum coke
I-petroleum coke ingumkhiqizo we-petroleum omnyama noma omnyama oqinile ocwebezelayo futhi unezimbotshana.Izingxenye ze-petroleum coke ama-hydrocarbon, aqukethe i-90-97% carbon, 1.5-8% ye-hydrogen, i-nitrogen, i-chlorine, isulfure kanye nezinhlanganisela zensimbi ezisindayo.
I-petroleum coke ingumkhiqizo we-pyrolysis kawoyela we-feedstock kumayunithi wokupheka abambezelekile emazingeni okushisa aphezulu ukukhiqiza imikhiqizo kawoyela elula.Umphumela we-petroleum coke cishe u-25-30% wamafutha aluhlaza.Inani layo eliphansi le-calorific cishe izikhathi ezingu-1.5-2 zamalahle, okuqukethwe komlotha akukhona ngaphezu kuka-0.5%, indaba eguquguqukayo imayelana ne-11%, futhi ikhwalithi iseduze ne-anthracite.
2. Izinga lekhwalithi ye-petroleum coke
I-petroleum coke ebambezelekile ibhekisela ku-coke eluhlaza ekhiqizwa iyunithi yokupheka ebambezelekile, eyaziwa nangokuthi i-coke evamile, futhi alikho izinga likazwelonke elihambisanayo njengamanje.Njengamanje, amabhizinisi okukhiqiza asekhaya ikakhulukazi akhiqiza ngokwezinga lemboni i-SH0527-92 elakhiwe yi-Sinopec Corporation yangaphambili.Izinga lihlukaniswa ngokuyinhloko ngokusho kokuqukethwe kwesibabule se-petroleum coke.Phakathi kwazo, i-coke yebanga lokuqala kanye ne-No.I-coke engunombolo 2 isetshenziswa embonini yokwenza i-aluminium.I-Electrode paste esetshenziswa kumaseli e-electrolytic (isithando somlilo) kanye nokukhiqizwa kwama-graphite electrode, i-coke engunombolo 3 isetshenziselwa ukukhiqizwa kwe-silicon carbide (izinto ezigugulekayo) ne-calcium carbide (i-calcium carbide), neminye imikhiqizo ye-carbon, nayo esetshenziswa ekwenzeni ama-anode amaseli ancibilikisa i-aluminium Ibhulokhi elingezansi futhi lisetshenziselwa ukuqhuma kwesithando somlilo wekhabhoni noma ukwakhiwa kwangaphansi kwesithando somlilo.
3. Ukusetshenziswa okuyinhloko kwe-petroleum coke
Ukusetshenziswa okuyinhloko kwe-petroleum coke ama-anode abhakwe ngaphambilini kanye nama-anode pastes asetshenziswa ku-aluminiyamu ye-electrolytic, izithuthukisi zekhabhoni zokukhiqiza imboni yekhabhoni, ama-electrode amagraphite, i-silicon yezimboni ezincibilikisayo, namafutha.
Ngokwesakhiwo nokubukeka kwe-petroleum coke, imikhiqizo ye-petroleum coke ingahlukaniswa ngezinhlobo ezi-4: i-coke yenaliti, i-sponge coke, i-projectile coke kanye ne-powder coke: (1) I-coke yenaliti, enesakhiwo esicacile senaliti kanye nokuthungwa kwe-fiber, esetshenziswa ikakhulukazi. okwenza i-steelmaking High-power graphite electrode kanye ne-ultra-high-power graphite electrode in Njengoba inaliti ye-coke inezidingo zenkomba eziqinile zekhwalithi ngokokuqukethwe kwesibabule, okuqukethwe komlotha, izinto eziguquguqukayo kanye nokuminyana kweqiniso, kunezidingo ezikhethekile zobuchwepheshe bokukhiqiza inaliti ye-coke kanye eluhlaza. izinto zokwakha.
(2) I-sponge coke, ene-high chemical reactivity kanye nokungcola okuphansi, isetshenziswa kakhulu embonini yokuncibilikisa i-aluminium kanye nemboni ye-carbon.
(3) I-projectile coke noma i-coke eyindilinga: Iyindilinga futhi inobubanzi obungu-0.6-30mm.Ngokuvamile ikhiqizwa kusuka kuwoyela osele we-sulfur kanye ne-asphaltene ephezulu futhi ingasetshenziswa kuphela njengezibaseli zezimboni ezifana nokukhiqiza amandla nosimende.
(4) I-powder coke: Ikhiqizwa inqubo yokupheka e-fluidized, enezinhlayiya ezinhle (ububanzi obungu-0.1-0.4mm), okuqukethwe okuguquguqukayo okuphezulu kanye ne-coefficient ephezulu yokwandisa ukushisa, futhi ayikwazi ukusetshenziswa ngokuqondile ekulungiseleleni i-electrode kanye nemboni ye-carbon.
