Tsono coke is silver-grey porous solid ine fiber texture direction, uye ine hunhu hwepamusoro crystallinity, high simba, high graphitization, low thermal expansion, low ablation, etc. Inoshandiswa zvakanyanya mukudzivirira nyika uye maindasitiri evagari a high-quality raw material yekugadzira graphite electrodes, bhatiri anode zvinhu uye yakakwirira-yekupedzisira kabhoni zvigadzirwa.

Zvinoenderana neyakasiyana kugadzirwa zvigadzirwa zvinoshandiswa, tsono coke inogona kupatsanurwa kuita marudzi maviri: mafuta-akavakirwa uye marasha-akavakirwa: tsono coke inogadzirwa kubva mupetroleum yekunatsa zvigadzirwa inonzi mafuta-based tsono coke, uye marasha tar pitch uye zvikamu zvayo Tsono coke. inogadzirwa kubva mumafuta inonzi coal-based needle coke.Kugadzirwa kwetsono coke nemafuta epetroleum kune zvakanakira kuchengetedza kwezvakatipoteredza, uye kuita kwacho hakuna kuoma uye mutengo wekugadzira wakaderera, saka yakabhadharwa zvakanyanya uye zvakanyanya kutariswa nevanhu.

Oiri-based tsono coke inogona kukamurwa kuita marudzi maviri: coke mbishi uye yakabikwa coke (calcined coke).Pakati pavo, coke mbishi inoshandiswa kugadzira akasiyana bhatiri negative electrode zvinhu, uye yakabikwa coke inoshandiswa kugadzira yakakwirira-simba graphite electrodes.Mumakore achangopfuura, nekuwedzera kwakasimba kwekuchengetedza kwezvakatipoteredza mamiriro, kukurumidza kuvandudza kwemagetsi matsva emagetsi kwakakonzera kudiwa kwakanyanya kwebhatiri anode zvinhu;panguva imwecheteyo, vashanduri vekare vemakambani esimbi vakatsiviwa nevira remagetsi.Pasi pemaitiro maviri, kudiwa kwemusika kwetsono coke kwakawedzera zvakanyanya.Parizvino, kugadzirwa kwemafuta-based tsono coke munyika kunotongwa nemakambani eAmerica, uye makambani mashoma akadai seJinzhou Petrochemical, Jingyang Petrochemical uye Yida New Materials akawana kugadzirwa kwakagadzikana munyika yangu.Zvigadzirwa zvepamusoro zvetsono coke zvinonyanya kuvimba nekutenga kunze kwenyika.Haisi mari yakawanda chete inotambiswa, asi inowanikwa nyore nyore.Izvo zvakakosha zvakakosha kukurumidza kutsvagisa nezvekugadzirwa kwetsono coke uye kuona iyo jacking kumusoro nekugadzira nekukurumidza sezvinobvira.

Raw material ndicho chinhu chakakosha chinokanganisa kunaka kwetsono coke.Yakakodzera mbishi zvinhu inogona kuderedza zvakanyanya kuoma kwekugadzira mesophase pitch uye kubvisa zvinotevera kusagadzikana zvinhu.Izvo zvigadzirwa zvekugadzira tsono coke zvinofanirwa kuve neanotevera maitiro:

①Zvirimo zvearomatics zvakakwirira, kunyanya zvirimo zve 3 uye 4-mhete pfupi yepaside cheni aromatics mumutsara kuronga zviri nani 40% kusvika 50%.Nenzira iyi, panguva yecarbonization, maaromatics molecules anonangana pamwe chete kuti aumbe akakura planar aromatics molecules, uye kuburikidza nehombe.π Makore akasungirirwa erekitironi akaiswa pamusoro peumwe neumwe kuti aumbe girafu rakakwana-rakafanana nelatisi yechimiro.

②Asphaltines uye macolloid aripo muchimiro chemolecular ye fused-ring hombe anonhuwirira mahydrocarbons ane zvakaderera zvemukati.Izvi zvinhu zvine simba molecular polarity uye yakakwirira reactivity., Zvinowanzodiwa kuti heptane insoluble nyaya iri pasi pe2%.

③Iyo sulfur yemukati haisi kupfuura 0.6%, uye iyo nitrogen yemukati haisi kupfuura 1%.Sarufa nenitrogen zviri nyore kupukunyuka nekuda kwekupisa kwakanyanya panguva yekugadzirwa kwemagetsi uye kukonzeresa kuzvimba kwegasi, izvo zvinokonzeresa kuputika kwemagetsi.

④Madota ari pasi pe 0.05%, uye hapana tsvina yemagetsi yakadai se catalyst powder, iyo ichaita kuti mhinduro ienderere mberi nekukurumidza panguva ye carbonization, kuwedzera kuoma kwekugadzira mesophase spheres, uye kukanganisa maitiro e coke.

⑤Zviri mukati mesimbi inorema sevanadium uye nickel ishoma pane 100ppm, nekuti macompounds anoumbwa nesimbi idzi ane catalytic effect, iyo inomhanyisa nucleation yemesophase spheres, uye zvinonetsa kuti mativi akure zvakakwana.Panguva imwecheteyo, kuvapo kweiyi tsvina yesimbi mune chigadzirwa kuchaitawo voids, Matambudziko akadai sekuputika anotungamirira kuderera kwesimba rechigadzirwa.

⑥Quinoline insoluble matter (QI) ndeye zero, QI inosungirirwa yakatenderedza mesophase, ichitadzisa kukura uye kusanganiswa kwemakristasi akatenderera, uye tsono coke chimiro chine yakanaka fiber chimiro haigone kuwanikwa mushure mekubika.

⑦Density yakakura kudarika 1.0g/cm3 kuona goho rakakwana rekoki.

Muchokwadi, mafuta ekudyisa anosangana nezvinodiwa pamusoro apa haashoma.Kubva pamaonero ezvikamu, catalytic kupaza mafuta slurry ine yakakwira inonhuhwirira, furfural yakabviswa mafuta, uye ethylene tar zvinhu zvakanakira kugadzirwa kwetsono coke.Catalytic cracking oil slurry ndeimwe yezvigadzirwa zvecatalytic unit, uye inowanzo tumirwa semafuta akachipa.Nekuda kwehuwandu hukuru hwekunhuhwirira huri mukati mayo, imhando yepamusoro yezvigadzirwa zvekugadzira tsono coke maererano nekuumbwa.Muchokwadi, pasi rese Iyo yakawanda yakawanda yezvigadzirwa zvetsono coke inogadzirwa kubva kune catalytic kupaza mafuta slurry.
