Inaliti ye-coke yisilivere-ngwevu eqinileyo eqinileyo ene-fiber texture ecacileyo, kwaye ineempawu zekristallini ephezulu, amandla aphezulu, i-graphitization ephezulu, ukwanda kwe-thermal ephantsi, ukuchithwa okuphantsi, njl. umgangatho ophezulu wezinto eziluhlaza zokwenziwa kwee-electrode zegraphite, izinto ze-anode zebhetri kunye neemveliso zekhabhoni eziphezulu.

Ngokwezixhobo ezahlukeneyo zemveliso ezisetyenzisiweyo, i-coke yenaliti inokwahlulwa ibe ziindidi ezimbini: esekwe kwi-oyile kunye nesekwe kumalahle: inaliti ye-coke eveliswe kwimveliso yokucokisa i-petroleum ibizwa ngokuba yi-oyile esekwe kwi-coke yenaliti, kunye ne-coal tar pitch kunye namaqhezu ayo. eveliswa kwioli ibizwa ngokuba yicoke yenaliti esekwe emalahleni.Ukuveliswa kwe-coke yenaliti kunye neemveliso zepetroleum kuneenzuzo ezibalaseleyo zokukhusela indalo, kwaye ukuphunyezwa akunzima kakhulu kwaye iindleko zokuvelisa ziphantsi, ngoko kuye kwahlawulwa ngakumbi nangakumbi ngabantu.

I-oyile yenaliti i-coke inokwahlulwa ibe ziindidi ezimbini: i-coke eluhlaza kunye ne-coke ephekiweyo (i-coke ene-calcined).Phakathi kwazo, i-coke eluhlaza isetyenziselwa ukuvelisa izixhobo ezahlukeneyo ze-electrode ezingalunganga, kwaye i-coke ephekiweyo isetyenziselwa ukuvelisa i-electrode yegraphite yamandla aphezulu.Kwiminyaka yakutshanje, kunye nemeko ekhulayo yokukhusela indalo, ukuphuhliswa ngokukhawuleza kwezithuthi zamandla amatsha kuye kwakhokelela kwimfuno ephezulu yezinto ze-anode zebhetri;ngelo xesha, abaguquli bexesha elidlulileyo beenkampani zetsimbi bathatyathelwa indawo yiziko zombane.Ngaphantsi kweempembelelo ezimbini, imfuno yemarike ye-coke yenaliti inyuke kakhulu.Okwangoku, i-oyile-based based oil coke production ilawulwa ziinkampani zaseMelika, kwaye kuphela iinkampani ezimbalwa ezifana neJinzhou Petrochemical, iJingyang Petrochemical kunye ne-Yida New Materials ziye zafumana imveliso ezinzileyo kwilizwe lam.Iimveliso ze-coke zenaliti eziphezulu zixhomekeke kakhulu ekungenisweni kwamanye amazwe.Ayichithwanga imali eninzi nje kuphela, kodwa ifumaneka lula.Kubaluleke kakhulu kwisicwangciso-qhinga ukukhawulezisa uphando kwinkqubo yokuvelisa inaliti ye-coke kunye nokuqonda ukukrazula imveliso ngokukhawuleza.

I-Raw material yinto ephambili echaphazela umgangatho wenaliti ye-coke.Imathiriyeli ekrwada efanelekileyo inokunciphisa kakhulu ubunzima bokwenza i-mesophase pitch kwaye isuse izinto ezingazinzanga ezilandelayo.Iimathiriyeli ekrwada yokuvelisa inaliti ye-coke kufuneka ibe nezi mpawu zilandelayo:

①Umxholo we-aromatics uphezulu, ngakumbi umxholo we-3 kunye ne-4-ring ye-aromatics yecala elifutshane elisecaleni kwi-linear lungiselelo likhethwa ukuba li-40% ukuya kuma-50%.Ngale ndlela, ngexesha le-carbonization, iimolekyuli ze-aromatics zihlangana enye kwenye ukuze zenze iimolekyuli ezinkulu ze-aromatics ezicwangcisiweyo, kwayeπ Amafu e-electron adityanisiweyo abekwe ngaphezulu kwelinye ukuze enze i-lattice yolwakhiwo olufana negraphite.

②I-asphaltenes kunye ne-colloids ekhoyo kwisakhiwo semolekyuli ye-fused-ring enkulu yeehydrocarbons ezinevumba elimnandi zinomxholo ophantsi.Ezi zinto zine-polarity eyomeleleyo yemolekyuli kunye nokusebenza kwakhona okuphezulu., Ngokuqhelekileyo kuyadingeka ukuba i-heptane i-insoluble matter ingaphantsi kwe-2%.

③Umxholo wesulfure awukho ngaphezu kwe-0.6%, kwaye umxholo we-nitrogen awukho ngaphezu kwe-1%.I-sulfure kunye ne-nitrogen kulula ukubaleka ngenxa yokushisa okuphezulu ngexesha lokuvelisa i-electrode kwaye kubangele ukudumba kwegesi, okuya kubangela ukuqhekeka kwi-electrodes.

④Umxholo womlotha ungaphantsi kwe-0.05%, kwaye akukho zixhobo ezingcolileyo ezifana ne-catalyst powder, eya kubangela ukuba ukusabela kuqhube ngokukhawuleza ngexesha le-carbonization, ukwandisa ubunzima bokwenza i-mesophase spheres, kunye nokuchaphazela iimpawu ze-coke.

⑤Umxholo wesinyithi esinzima njenge-vanadium kunye ne-nickel ingaphantsi kwe-100ppm, kuba iikhompawundi eziqulunqwe zezi zinyithi zinefuthe le-catalytic, eliya kukhawulezisa i-nucleation ye-mesophase spheres, kwaye kunzima ukuba ama-spheres akhule ngokwaneleyo.Ngelo xesha, ubukho bobu kungcola kwesinyithi kwimveliso kuya kubangela ukuba i-voids, Iingxaki ezifana nokuqhekeka kukhokelela ekunciphiseni amandla emveliso.

⑥I-Quinoline i-insoluble matter (i-QI) yi-zero, i-QI iya kudityaniswa malunga ne-mesophase, ithintele ukukhula kunye nokudityaniswa kweekristale ze-spherical, kunye nesakhiwo senaliti ye-coke ene-fiber structure ayinakufumaneka emva kokupheka.

⑦Ubuninzi bukhulu kune-1.0g/cm3 ukuqinisekisa isivuno esaneleyo se-coke.

Enyanisweni, ii-oyile ze-feedstock ezihlangabezana nezi mfuno zingentla zinqabile.Ngokwembono yamacandelo, i-oyile yokuqhekeka i-slurry enomxholo ophezulu onevumba elimnandi, i-oyile ekhutshwe nge-furfural, kunye ne-ethylene tar zizixhobo ezifanelekileyo zokuvelisa inaliti ye-coke.I-Catalytic cracking oil slurry yenye yeemveliso zeyunithi yecatalytic, kwaye ihlala ithunyelwa njengeoyile yexabiso eliphantsi.Ngenxa yobuninzi bezinto ezivumbayo kuyo, yimathiriyeli ekrwada ephezulu yokuveliswa kwenaliti ye-coke ngokwemiqathango yokubunjwa.Ngapha koko, kwihlabathi liphela Uninzi lweemveliso zeenaliti ze-coke zilungiswa ukusuka kwi-oyile eqhekekileyo eyi-slurry.
