Izinga Lokukhetha I-Coke

Izinga le-petroleum coke lincike kakhulu esimweni sempahla eluhlaza kanye nezimo zayo zokucubungula.Izinkomba zekhwalithi eziyinhloko yilezi:

Ubumsulwa
Kubhekisela kokuqukethwe sulphur nomlotha ku-petroleum coke.I-high-sulfur coke izobangela ukuthi umkhiqizo uvuvuke ngesikhathi se-graphitization, okuholela ekuqhekekeni komkhiqizo wekhabhoni.Okuqukethwe komlotha okuphezulu kuzovimbela ukwakheka kwekristalu kwesakhiwo futhi kuthinte ukusebenza kwemikhiqizo yekhabhoni.

I-Crystallinity
Kubhekisela esakhiweni se-coke kanye nobukhulu bezinhlayiya ze-mesophase.I-coke eyakhiwe ama-sphere amancane inesakhiwo esinezimbotshana njengesipontshi, kanti i-coke eyakhiwe yizindilinga ezinkulu inesakhiwo esiminyene njenge-fibrous noma njengenaliti, futhi ikhwalithi yayo iphakeme kune-sponge coke.Kunkomba yekhwalithi, ukuminyana kwangempela cishe kumele lokhu kusebenza, futhi ukuminyana kweqiniso okuphezulu kubonisa ukucwebezela okuhle.

Ukumelana nokushaqeka okushisayo
Isho ukumelana nokuqhekeka kwemikhiqizo ye-coke lapho ihlaselwa ukushaqeka okushisayo okukhuphuka ngokuzumayo kuye kumazinga okushisa aphezulu noma kuphole ngokushesha ngenxa yokushisa okuphezulu.Imikhiqizo ye-needle coke inokumelana nokushaqeka okuhle kwe-thermal, ngakho-ke inenani eliphezulu lokusetshenziswa.I-coefficient yokunwetshwa kwe-thermal imele lesi sakhiwo.Lapho i-coefficient ephansi yokwanda okushisayo, kuba ngcono ukumelana nokushaqeka kokushisa.

Ukusanhlamvu
Okuqukethwe okuhlobene kwe-coke eyimpuphu kanye ne-coke enkulu ye-granular (i-coke esebenzisekayo) equkethwe ku-coke yokusabela.Iningi le-powder coke liphulwa yisenzo somshini njengokungqubuzana kwe-extrusion ohlelweni lokuhlobisa, ukugcinwa nokuthutha, ngakho-ke inani layo liphinde libonise amandla omshini.I-coke eluhlaza ingavinjelwa ukuba iphulwe ngemva kokuba i-calcined ukuze ikhule i-coke.I-coke ene-granular coke kanye ne-powder coke encane inenani eliphezulu lokusetshenziswa.
