Tsebo ea petroleum coke le calcined petroleum coke
1. Petroleum coke
Petroleum coke ke sehlahisoa sa petroleum e ntšo kapa e bohlooho bo lefifi e nang le tšepe e khanyang 'me e na le masoba.Likarolo tsa coke tsa petroleum ke li-hydrocarbon, tse nang le 90-97% carbon, 1.5-8% ea hydrogen, nitrogen, chlorine, sulfur le metsoako ea tšepe e boima.
Petroleum coke ke sehlahisoa sa pyrolysis ea oli ea feedstock ka har'a likarolo tsa ho pheha tse liehang ka mocheso o phahameng ho hlahisa lihlahisoa tsa oli e bobebe.Sephetho sa petroleum coke ke hoo e ka bang 25-30% ea oli e tala.Khalori ea eona e tlaase ea lik'halori e ka ba makhetlo a 1.5-2 a mashala, molora oa molora ha o fetang 0.5%, taba e sa tsitsang e ka bang 11%, 'me boleng bo haufi le anthracite.
2. Tekanyetso ea boleng ba petroleum coke
Ho lieha ha petroleum coke ho bolela coke e tala e hlahisoang ke yuniti e liehileng ea ho pheha, e tsejoang hape e le coke e tloaelehileng, 'me ha ho na maemo a naha a tsamaellanang hajoale.Hajoale, likhoebo tsa tlhahiso ea malapeng li hlahisa haholo ho latela maemo a indasteri SH0527-92 a hlophisitsoeng ke Sinopec Corporation ea mehleng.Tekanyetso e arotsoe haholo ho latela sebabole sa coke ea petroleum.Har'a tsona, coke ea sehlopha sa pele le No. 1 coke li loketse ho etsa li-electrode tse tloaelehileng tsa matla a graphite indastering ea tšepe, hape li loketse k'habone ea aluminium indastering ea ho etsa aluminium;No. 2 coke e sebelisoa indastering ea ho etsa aluminium.Electrode peiste e sebelisoang liseleng tsa electrolytic (sebōpi) le tlhahiso ea li-electrode tsa graphite, No. 3 coke e sebelisoa bakeng sa tlhahiso ea silicon carbide (lisebelisoa tsa abrasive) le calcium carbide (calcium carbide), le lihlahisoa tse ling tsa carbon, tse sebelisoang hape ha ho etsoa. anodes bakeng sa aluminium lisele tse qhibilihisang Boloko bo ka tlaase 'me bo sebelisetsoa ho phatloha sebōpi sa carbon lening setene kapa mohaho o ka tlaase oa sebōpi.
3. Tšebeliso e ka sehloohong ea petroleum coke
Tšebeliso ea mantlha ea coke ea petroleum ke li-anode tse phehiloeng pele le li-anode pastes tse sebelisoang ka aluminium ea electrolytic, tlhahiso ea indasteri ea k'habone e ntlafatsang k'habone, li-electrode tsa graphite, silicon ea indasteri e qhibilihisang, le mafura.
Ho ea ka sebopeho le ponahalo ea coke ea petroleum, lihlahisoa tsa petroleum coke li ka aroloa ka mefuta e 4: coke ea nale, seponche coke, projectile coke le phofo coke: (1) nale coke, e nang le sebopeho se hlakileng sa nale le sebopeho sa fiber, se sebelisoang haholo-holo. for steelmaking Matla a phahameng a li-electrode tsa graphite le li-electrode tsa graphite tsa ultra-high-power ka Kaha nale coke e na le litlhoko tse thata tsa index ea boleng ho latela litaba tsa sebabole, litaba tsa molora, taba e tsitsitseng le boima ba 'nete, ho na le litlhoko tse khethehileng tsa theknoloji ea tlhahiso ea nale coke le e tala. lisebelisoa.
(2) Coke ea seponche, e nang le lik'hemik'hale tse phahameng tsa lik'hemik'hale le lintho tse fokolang tse sa hloekang, e sebelisoa haholo indastering ea ho qhibilihisa aluminium le indasteri ea carbon.
(3) Projectile coke kapa spherical coke: E sebopeho se chitja le bophara ba 0.6-30mm.Ka kakaretso e hlahisoa ka oli ea sebabole e phahameng le e phahameng ea asphaltene 'me e ka sebelisoa feela e le mafura a indasteri a kang ho hlahisa matla le samente.
(4) Powder coke: E hlahisoa ke mokhoa oa ho pheha metsi, o nang le likaroloana tse ntle (ka bophara ba 0.1-0.4mm), lihlahisoa tse phahameng tse sa tsitsang le coefficient e phahameng ea ho atolosa mocheso, 'me e ke ke ea sebelisoa ka ho toba ho lokisetsa li-electrode le indasteri ea carbon.
