Singano coke ndi siliva-imvi porous olimba ndi zoonekeratu CHIKWANGWANI kapangidwe malangizo, ndipo ali ndi makhalidwe a mkulu crystallinity, mphamvu mkulu, mkulu graphitization, otsika matenthedwe kufutukuka, otsika ablation, etc. Iwo ali ntchito yapadera mu chitetezo dziko ndi mafakitale wamba Ndi zida zapamwamba kwambiri zopangira ma elekitirodi a graphite, zida za anode za batri ndi zida zapamwamba za carbon.

Malinga ndi zopangira zosiyanasiyana zomwe zimagwiritsidwa ntchito, singano ya singano imatha kugawidwa m'mitundu iwiri: yopangira mafuta komanso yopangira malasha: singano ya singano yopangidwa kuchokera kumafuta oyenga mafuta amatchedwa mafuta opangidwa ndi singano coke, ndi phula la malasha ndi tizigawo ting'onoting'ono. opangidwa kuchokera ku mafuta amatchedwa coke-based needle coke.Kupanga singano coke ndi zinthu za petroleum kuli ndi ubwino woteteza zachilengedwe, ndipo kukhazikitsa kwake sikovuta komanso mtengo wopangira ndi wotsika, chifukwa chake anthu amalipira chidwi kwambiri.

Mafuta a singano atha kugawidwa m'mitundu iwiri: coke yaiwisi ndi coke yophika (calcined coke).Pakati pawo, coke yaiwisi imagwiritsidwa ntchito popanga zida zosiyanasiyana za batri zopanda ma elekitirodi, ndipo coke yophika imagwiritsidwa ntchito kupanga ma elekitirodi amphamvu kwambiri a graphite.M'zaka zaposachedwa, ndi momwe zinthu zikuchulukirachulukira zoteteza chilengedwe, kutukuka kwachangu kwa magalimoto amagetsi atsopano kwapangitsa kuti pakhale kufunikira kwakukulu kwa zida za anode za batri;panthawi imodzimodziyo, otembenuza achikale a makampani azitsulo asinthidwa ndi ng'anjo zamagetsi.Pansi pazigawo ziwiri, kufunikira kwa msika kwa coke singano kwakula kwambiri.Pakalipano, kupanga mafuta opangidwa ndi singano padziko lonse lapansi kumayendetsedwa ndi makampani a ku America, ndipo makampani ochepa okha monga Jinzhou Petrochemical, Jingyang Petrochemical ndi Yida New Materials apeza kupanga kokhazikika m'dziko langa.Zogulitsa za singano zapamwamba kwambiri zimadalira kuchokera kunja.Sikuti ndalama zambiri zimangowonongeka, komanso zimakhala zosavuta.Ndikofunikira kwambiri kufulumizitsa kafukufuku pakupanga singano coke ndikuzindikira kuthamangitsidwa ndi kupanga posachedwa.

Zopangira ndizofunika kwambiri zomwe zimakhudza mtundu wa singano.Zoyenera zopangira zimatha kuchepetsa kwambiri zovuta kupanga phula la mesophase ndikuchotsa zinthu zosakhazikika.Zopangira zopangira singano za coke ziyenera kukhala ndi izi:

①Zomwe zili mu aromatics ndizokwera kwambiri, makamaka zomwe zili mu 3 ndi 4-ring short side chain aromatics mu mzere wotsatira makamaka 40% mpaka 50%.Mwanjira iyi, panthawi ya carbonization, mamolekyu a aromatics amalumikizana wina ndi mzake kuti apange mamolekyu akuluakulu a aromatics, ndi kupyolera mu lalikulu.π Mitambo ya ma elekitironi yomangika imayikidwa pamwamba pa wina ndi mzake kuti ipange galafi yofanana ndi graphite.

②Ma asphaltines ndi ma colloid omwe amapezeka m'maselo a ma hydrocarbons osakanikirana ndi mphete zazikulu zonunkhira amakhala ndi zotsika.Zinthu izi zimakhala ndi polarity yolimba ya mamolekyulu komanso kuchitapo kanthu kwakukulu., Nthawi zambiri pamafunika kuti zinthu zosasungunuka za heptane zikhale zosakwana 2%.

③Sulfure zili ndi 0.6%, ndipo nayitrogeni saposa 1%.Sulfure ndi nayitrogeni ndizosavuta kuthawa chifukwa cha kutentha kwambiri panthawi yopanga ma elekitirodi ndipo zimayambitsa kutupa kwa gasi, zomwe zingayambitse ming'alu yamagetsi.

④Phulusa la phulusa ndi losakwana 0.05%, ndipo palibe zonyansa zamakina monga catalyst powder, zomwe zidzapangitse kuti zochitazo zipitirire mofulumira panthawi ya carbonization, kuonjezera vuto la kupanga magawo a mesophase, ndikukhudza katundu wa coke.

⑤Zomwe zili muzitsulo zolemera monga vanadium ndi nickel ndi zosakwana 100ppm, chifukwa mankhwala omwe amapangidwa ndi zitsulozi amakhala ndi mphamvu zowonjezera, zomwe zidzafulumizitsa nucleation ya mesophase spheres, ndipo zimakhala zovuta kuti zigawozo zikule mokwanira.Panthawi imodzimodziyo, kukhalapo kwa zonyansa zazitsulozi muzinthuzo kungayambitsenso voids, Mavuto monga ming'alu amachititsa kuchepa kwa mphamvu ya mankhwala.

⑥Quinoline insoluble matter (QI) ndi ziro, QI idzalumikizidwa mozungulira mesophase, kulepheretsa kukula ndi kuphatikizika kwa makhiristo ozungulira, ndipo kapangidwe ka singano kokhala ndi ulusi wabwino sikungapezeke pambuyo pophika.

⑦Kachulukidwe ndi wamkulu kuposa 1.0g/cm3 kuonetsetsa zokolola zokwanira za coke.

M'malo mwake, mafuta amafuta omwe amakwaniritsa zofunikira pamwambapa ndi osowa.Kuchokera pamalingaliro azinthu, slurry wosweka wamafuta omwe ali ndi zonunkhira zambiri, mafuta opangidwa ndi furfural, ndi ethylene tar ndi zida zabwino zopangira singano.Catalytic cracking oil slurry ndi imodzi mwazinthu zopangidwa ndi zida zothandizira, ndipo nthawi zambiri zimatumizidwa ngati mafuta otsika mtengo.Chifukwa cha kuchuluka kwa zonunkhira zomwe zili mmenemo, ndizitsulo zapamwamba kwambiri zopangira singano coke potengera kapangidwe kake.M'malo mwake, padziko lonse lapansi Zinthu zambirimbiri za singano za coke zimakonzedwa kuchokera ku slurry yosweka yamafuta.
