Kudziwa mafuta a petroleum coke ndi calcined petroleum coke
1. Mafuta a coke
Petroleum coke ndi chinthu chakuda kapena chotuwa cholimba cholimba chamafuta chokhala ndi zitsulo zonyezimira ndipo chimakhala ndi porous.Mafuta a coke amafuta ndi ma hydrocarbon, okhala ndi 90-97% ya kaboni, 1.5-8% haidrojeni, nayitrogeni, chlorine, sulfure ndi zitsulo zolemera.
Petroleum coke ndi wopangidwa kuchokera ku pyrolysis wa feedstock mafuta mu magawo ochedwa coking pa kutentha kwambiri kuti apange mafuta opepuka.Kutulutsa kwa petroleum coke ndi pafupifupi 25-30% yamafuta osaphika.Mtengo wake wochepa wa calorific uli pafupi ndi 1.5-2 nthawi ya malasha, phulusa siliposa 0,5%, chinthu chosasunthika chili pafupi ndi 11%, ndipo khalidweli liri pafupi ndi anthracite.
2. Muyezo wamtengo wapatali wa petroleum coke
Mafuta ochedwa coke amatanthauza coke wobiriwira wopangidwa ndi kagawo kakang'ono ka coking, komwe kamadziwikanso kuti coke wamba, ndipo palibe mulingo wofananira wa dziko pano.Pakadali pano, mabizinesi opanga zoweta amatulutsa makamaka malinga ndi muyezo wamakampani SH0527-92 wopangidwa ndi omwe kale anali Sinopec Corporation.Muyezo umayikidwa makamaka malinga ndi sulfure zomwe zili mu petroleum coke.Pakati pawo, kalasi yoyamba ya coke ndi No.No. 2 coke imagwiritsidwa ntchito popanga aluminiyamu.Electrode phala ntchito electrolytic maselo (ng'anjo) ndi kupanga maelekitirodi graphite, No. 3 coke ntchito kupanga pakachitsulo carbide (abrasive zinthu) ndi kashiamu carbide (calcium carbide), ndi zinthu zina mpweya, amagwiritsidwanso ntchito popanga manode a aluminiyamu osungunula maselo Pansi chipika ndipo amagwiritsidwa ntchito pophulitsa ng'anjo ya kaboni yokhala ndi njerwa kapena ng'anjo pansi.
3. Ntchito yaikulu ya petroleum coke
Zomwe zimagwiritsidwa ntchito kwambiri ndi mafuta a petroleum coke ndi ma anode ophika kale ndi phala la anode lomwe limagwiritsidwa ntchito mu aluminiyamu ya electrolytic, makina opanga mpweya wa carbon industry, ma electrode a graphite, smelting silicon fakitale, ndi mafuta.
Malinga ndi kapangidwe ndi maonekedwe a petroleum coke, petroleum coke mankhwala akhoza kugawidwa mu mitundu 4: singano coke, siponji coke, projectile coke ndi ufa coke: (1) singano coke, ndi zoonekeratu kapangidwe singano woboola pakati ndi makulidwe CHIKWANGWANI, makamaka ntchito. kwa steelmaking High-mphamvu graphite maelekitirodi ndi kopitilira muyeso-mkulu-mphamvu graphite maelekitirodi mu Popeza singano coke ali okhwima khalidwe index amafuna mawu a sulfure okhutira, phulusa, zinthu kosakhazikika ndi kachulukidwe weniweni, pali zofunika zapadera singano coke kupanga luso ndi yaiwisi. zipangizo.
(2) Sponge coke, yokhala ndi reactivity yapamwamba yamankhwala komanso zonyansa zochepa, imagwiritsidwa ntchito makamaka m'makampani osungunula aluminiyamu ndi mafakitale a carbon.
(3) Coke ya projectile kapena coke yobulungira: Ndi yozungulira komanso 0.6-30mm m'mimba mwake.Nthawi zambiri amapangidwa kuchokera ku mafuta otsalira a sulfure ndi asphaltene ndipo angagwiritsidwe ntchito ngati mafuta opangira mafakitale monga kupanga magetsi ndi simenti.
(4) Powder coke: Imapangidwa ndi njira yopangira madzi, yokhala ndi tinthu tating'onoting'ono (0.1-0.4mm m'mimba mwake), zomwe zimakhala zosakhazikika komanso kuchuluka kwamafuta owonjezera, ndipo sizingagwiritsidwe ntchito mwachindunji pokonzekera ma elekitirodi ndi mafakitale a kaboni.
