Main Classification
Petroleum coke kazhinji ine nzira ina dzinotevera dzekuisa:
Zvinoenderana nemaitiro ekugadzirisa, inogona kukamurwa kuita coke yakabikwa uye yakabikwa coke.
Iyo yekutanga inowanikwa kubva kune coke tower yeakanonoka coking unit, inozivikanwawo se coke mbishi, iyo ine zvinhu zvakanyanya kushanduka uye ine simba rakashata;
Zvinoenderana nehuwandu hwehuwandu hwesarufa
Inogona kukamurwa kuva high-sarufa coke (yakawanda yesarufa yakakwira kupfuura 4%), yepakati-sarufa coke (sarufa yemukati iri 2% ~ 4%) uye yakaderera-sarufa coke (sarufa yemukati yakaderera pane 2%). .
Iyo sulfur yemukati yecoke inonyanya kuenderana nesarufa yemukati yemafuta mbishi.Sezvo zvinyorwa zvesarufa zvichiwedzera, kunaka kwekoki kunoderera, uye kushandiswa kwayo kunoshanduka maererano.
Zvinoenderana neyakasiyana microstructure
Inogona kukamurwa kuita chipanje coke uye tsono coke.Iyo yekutanga ine porous sesiponji, inozivikanwawo seyakajairwa coke.Iyo yekupedzisira yakaoma uye ine fibrous, inozivikanwawo seyepamusoro-mhando coke;
Yakasiyana zvakanyanya nesponge coke mumidziyo, uye ine hunhu hwehupamhi hwepamusoro, kuchena kwepamusoro, simba rakawanda, yakaderera sarufa yemukati, yakaderera ablation huwandu, yakaderera thermal yekuwedzera coefficient uye yakanaka thermal shock resistance;mune thermal conductivity, magetsi conductivity, magnetic conductivity uye Zvose zvine anisotropy yakajeka optically;iyo pores yakakura uye shoma, zvishoma elliptical, nzvimbo yakatsemuka ine chimiro chakajeka chekugadzirwa, uye kubata kunonatswa.Tsono coke inogadzirwa zvakanyanya kubva muoiri yakasara ine yakakwira yemukati yemahydrocarboni anonhuhwirira uye zvishoma zviri mukati mezvisina-hydrocarbon tsvina.
Muzvimiro zvakasiyana
Inogona kukamurwa kuita tsono coke, projectile coke kana spherical coke, sponge coke uye poda coke.
(1) Tsono coke: Iine hurongwa hwakajeka hwetsono uye fiber texture, uye inonyanya kushandiswa kune yakakwirira-simba uye ultra-high-simba graphite electrodes mukugadzira simbi.
(2) Sponge coke: yakakwira sulfur yemukati, yakakwira mwando yemukati, yakaoma nzvimbo uye mutengo wakakwira.
(3) projectile coke kana spherical coke: chimiro chakaita denderedzwa, dhayamita iri 0.6 ~ 30mm, uye mvura yemukati yakadzikira nekuda kwenzvimbo yakatsetseka.Kazhinji, inogadzirwa kubva kune yakakwirira-sarufa uye yakakwirira-asphaltene yakasara mafuta, iyo inogona kushandiswa chete kugadzira simba, simende uye mamwe maindasitiri emafuta.
(4) Powder coke: Inobudiswa neradial fluidization coking process, uye zvikamu zvayo zvine high thermal kuwedzera coefficient of volatile content (diameter 0.1 ~ 0.4mm) uye haigoni kushandiswa zvakananga mukugadzirisa electrode uye carbon industry.
