Ukuhlukaniswa Okuyinhloko
I-petroleum coke ngokuvamile inezindlela ezine ezilandelayo zokuhlukanisa:
Ngokwendlela yokucubungula, ingahlukaniswa i-coke eluhlaza kanye ne-coke ephekiwe.
Owokuqala utholakala kumbhoshongo we-coke weyunithi yokupheka ebambezelekile, eyaziwa nangokuthi i-coke eluhlaza, equkethe izinto ezishintshashintshayo futhi enamandla ampofu;
Ngokwezinga lokuqukethwe kwesibabule
Ingahlukaniswa nge-high-sulphur coke (inqwaba yesulfure ingaphezu kuka-4%), i-coke yesulphur ephakathi (okuqukethwe isulfure ngu-2% ~ 4%) kanye ne-coke yesulfure ephansi (okuqukethwe kwesibabule kungaphansi kuka-2%). .
Okuqukethwe kwesibabule ku-coke ikakhulukazi kuncike esibabuleni samafutha aluhlaza.Njengoba okuqukethwe kwesibabule kwanda, ikhwalithi ye-coke iyancipha, futhi ukusetshenziswa kwayo kushintsha ngokufanele.
Ngokusho kwe-microstructure ehlukene
Ingahlukaniswa i-sponge coke ne-coke yenaliti.Owokuqala unezimbobo njengesipontshi, owaziwa nangokuthi i-coke evamile.Lesi sakamuva siminyene futhi sine-fibrous, eyaziwa nangokuthi i-coke yekhwalithi ephezulu;
Ihluke kakhulu ku-sponge coke ezindaweni, futhi inezici zokuminyana okuphezulu, ukuhlanzeka okuphezulu, amandla aphezulu, okuqukethwe kwesibabule esincane, inani eliphansi le-ablation, i-coefficient ephansi yokwandisa okushisayo kanye nokumelana nokushaqeka okuhle kokushisa;ku-thermal conductivity, conductivity kagesi, conductivity kazibuthe futhi Zonke zine-anisotropy ebonakalayo ebonakalayo;ama-pores makhulu futhi ambalwa, a-elliptical kancane, indawo eqhekekile inesakhiwo esicacile sokuthungwa, futhi ukuthinta kugcotshiwe.I-needle coke ikhiqizwa kakhulu ngamafutha ayinsalela anokuqukethwe okuphezulu kwama-hydrocarbon anephunga elimnandi kanye nokuqukethwe okuncane kokungcola okungeyona i-hydrocarbon.
Ngezinhlobo ezahlukene
Ingahlukaniswa nge-coke yenaliti, i-projectile coke noma i-spherical coke, i-sponge coke ne-powder coke.
(1) I-coke yenaliti: Inokwakheka okusobala njengenaliti kanye nokuthungwa kwefayibha, futhi isetshenziselwa ikakhulukazi amandla aphezulu kanye nama-electrode e-graphite aphezulu kakhulu ekwenzeni insimbi.
(2) I-sponge coke: isibabule esiphezulu, umswakama ophezulu, indawo embi kakhulu kanye nenani eliphezulu.
(3) i-projectile coke noma i-spherical coke: umumo uyindilinga, ububanzi buyi-0.6 ~ 30mm, futhi okuqukethwe kwamanzi kuphansi ngenxa yendawo ebushelelezi.Ngokuvamile, ikhiqizwa ngamafutha e-high-sulfur kanye ne-asphaltene ephezulu, engasetshenziswa kuphela ekukhiqizeni amandla kagesi, usimende namanye amafutha ezimboni.
(4) I-powder coke: Ikhiqizwa inqubo yokupheka i-radial fluidization, futhi izinhlayiya zayo zine-coefficient ephezulu yokwandisa ukushisa kokuqukethwe okuguquguqukayo (ububanzi obungu-0.1 ~ 0.4mm) futhi ayikwazi ukusetshenziswa ngokuqondile ekulungiseleleni i-electrode kanye nemboni ye-carbon.
