Koke ya Calcined ni ubwoko bwa kaburizeri na koke ya peteroli ifite imiterere itandukanye.
Ibipimo by'ingenzi by'ibicuruzwa bya grafiti ni ￠150-￠1578 n'izindi moderi. Ni ngombwa cyane ku bigo by'ibyuma n'ibyuma, ibigo by'inganda bya silikoni polysilicon, ibigo by'imyuga, inganda z'ibikoresho by'indege n'ibindi bicuruzwa.
1: Koka ya peteroli
Peteroli coke ni igikoresho cy’amavuta gikomeye cy’umukara cyangwa imvi yijimye gifite ubwiza bw’icyuma kandi gifite imyenge. Ni ibikoresho bifite utuntu duto, nk’inkingi, cyangwa nk’udushinge twa karubone bigizwe n’utubuye duto twa grafiti.
Koke ya peteroli igizwe na hydrocarbons, 90-97% bya karuboni, 1.5-8% bya hydrogen, azote, chlorine, sulfure, n'ibinyabutabire bikomeye.
Koke ya peteroli ni umusaruro ukomoka kuri pyrolysis y'amavuta mabi mu gice cyo guteka cyatinze kugira ngo ikore amavuta yoroshye ku bushyuhe bwinshi.
Umusaruro wa peteroli coke ni hafi 25-30% by'umusaruro w'amavuta mabi.
Agaciro kayo ka karori nke ni inshuro 1.5-2 z'amakara, ivu ntirirenga 0.5%, ihindagurika ry'ikirere ni hafi 11%, kandi ubwiza bwayo buri hafi ya anthracite.
2: Igipimo cy'ubuziranenge cya peteroli coke. Coke ya peteroli yatinze yerekeza kuri coke ikorwa n'icyuma gipima koke cyatinze, kizwi kandi nka coke isanzwe, nta gipimo ## gihuye nacyo.
Kugeza ubu, ibigo bitunganya umusaruro imbere mu gihugu ahanini bitanga umusaruro hakurikijwe amahame ngenderwaho y’inganda SH0527-92 yashyizweho n’icyahoze ari ikigo cy’ubushinwa cya peteroli.
Ibipimo ngenderwaho ahanini bishyirwa mu byiciro hakurikijwe ingano ya sulfure iri muri peteroli ya coke.
Koke ya mbere ikwiriye gukorwamo electrode isanzwe ya grafiti mu nganda zikora ibyuma, kandi ikoreshwa nka karuboni mu gutunganya aluminiyumu
Koke ya 2 ikoreshwa mu gukora electrode paste na graphite electrode mu turemangingo twa electrolytic (ifuru) mu nganda zitunganya aluminium
Koke Nomero 3 ikoreshwa mu gukora karuboni ya silikoni (ibikoresho byo gusya) na karuboni ya silikoni (karuboni ya silikoni), ndetse n'ibindi bicuruzwa bya karuboni, ndetse no mu gukora ibibumbano bya anode byo gushongesha aluminiyumu no mu kubaka amatafari ya karuboni cyangwa hasi mu itanura riturika.
3: INKORESHO Y'INGENZI YA PETROLI YA COKE
INKORESHO nyamukuru za peteroli ya coke ni anode itekeshejwe mbere na paste ya anode mu gukora aluminiyumu ikoresha amashanyarazi, gukora karuboni ikoresha carbonizing agent, electrode ya grafiti, silicon ishongesha lisansi n'ibikomoka ku mavuta, n'ibindi.
Dukurikije imiterere n'isura ya peteroli, ibikomoka kuri peteroli bishobora kugabanywamo ifu ya koke, ifu ya koke isanzwe, ifu ya koke ikozwe mu ruganda rwa peteroli na koke ikozwe mu ruganda rwa porutugali:
(1) Coke ifite ishusho nk'iy'urushinge, ifite imiterere isa n'iy'urushinge n'imiterere ya fibre igaragara, ikoreshwa cyane cyane nk'iy'amashanyarazi ya grafiti ifite imbaraga nyinshi na electrode ya grafiti ifite imbaraga nyinshi cyane mu gukora ibyuma.
Kubera ko ifu ya needle coke ifite ibisabwa bikomeye mu gupima ubuziranenge bw'ibipimo bya sulfur, ivu, ubwinshi bw'ibikomoka ku ivu n'ubucucike nyakuri, hari ibisabwa byihariye ku ikoranabuhanga ryo gukora n'ibikoresho fatizo bya needle coke.
(2) Koke ya siponji, ifite ubushobozi bwinshi bwo gukora imiti n'umwanda muke, ikoreshwa cyane cyane mu nganda zitunganya aluminium n'inganda zitunganya karuboni.
(3) Koke ikoze mu buryo bwa projectile cyangwa koke y’umubumbe: ifite ishusho y’umubumbe na mm 0.6-30 z’umurambararo. Muri rusange ikorwa mu bisigazwa bya sulfure nyinshi n’ibisigazwa bya asphaltene byinshi kandi ishobora gukoreshwa gusa mu gutanga amashanyarazi, sima n’ibindi bikomoka ku nganda.
(4) Ifu ya coke: ikorwa hakoreshejwe uburyo bwo guconga bukozwe mu buryo bw'amazi hamwe n'uduce duto (umurambararo: 0.1-0.4mm), ingano nini y'ihindagurika ry'ikirere hamwe n'ubushyuhe bwinshi, bityo ntishobora gukoreshwa mu buryo butaziguye mu gutegura electrode no mu nganda za karuboni.
4: Koka ya peteroli ifite calcium
Iyo electrode ya grafiti ikoreshwa mu gukora ibyuma cyangwa electrode ishongesha (electrode ishongesha) ya aluminiyumu na manyeziyumu, kugira ngo ikore peteroli coke (coke) yujuje ibisabwa, coke igomba kuba irimo calcium.
Ubushyuhe bwa calcium muri rusange buba buri kuri dogere 1300°C, intego yabyo ikaba ari ukuvanaho naphthol coke volatilization uko bishoboka kose.
Muri ubu buryo, ingano ya hydrogen mu bikomoka kuri peteroli ya coke ishobora kugabanuka, urwego rwa graphitization ya coke ya peteroli rushobora kunozwa, imbaraga z'ubushyuhe bwinshi n'ubudahangarwa bw'ubushyuhe bya electrode ya graphite bishobora kunozwa, kandi amashanyarazi ya electrode ya graphite ashobora kunozwa.
Calcining ikoreshwa cyane cyane mu gukora electrode ya grafiti, ibicuruzwa bya karuboni, umucanga wa diyama, inganda za fosifore zo mu rwego rw'ibiribwa, inganda zikora ibyuma na karuboni, muri zo electrode ya grafiti ikoreshwa cyane.
Coke idafunze ishobora gukoreshwa mu buryo butaziguye nka karubide ya calcium, karubide ya silicon na karubide ya boron nk'ibikoresho byo gusya.
Ishobora kandi gukoreshwa mu buryo butaziguye nk'ibumba rya coke mu itanura ry'ibisasu rikoreshwa mu nganda cyangwa mu ibumba ry'ibisasu rikoreshwa mu ibumba rya karuboni, ishobora no gukoreshwa mu gucukura coke nto, nibindi.
