Itandukaniro ry'ingenzi hagati ya Peteroli Coke na Needle Coke n'ingaruka zabyo ku bwiza bwa Electrode

I. Itandukaniro mu bikoresho fatizo n'uburyo bikorerwa

Coke ya Peteroli

• Ibikoresho by’ibanze: Bigizwe ahanini n’amavuta menshi cyangwa amavuta asigaye akomoka ku gutogosha amavuta mabi, afite umwanda mwinshi (urugero: sulfur, vanadium, nickel).
• Uburyo: Yakozwe binyuze mu guteka buhoro buhoro, ikora imiterere isa n'iy'ikirungo nyuma yo gucikamo ubushyuhe bwinshi, ifite imyenge minini (kugeza kuri >0.3 cm³/g) kandi ikaba ishobora kwangirika n'ubushuhe.
• Igiciro: Uburyo bworoshye bwo gukora bufite ibiciro biri hasi, ariko ubwiza buhinduka cyane bitewe no kwishingikiriza ku buryo ibikoresho fatizo bihamye bigumaho.

Koka y'urushinge

• Ibikoresho fatizo: Bisaba amavuta ya peteroli make kandi adafite azote nyinshi (urugero: amavuta agabanya ubushyuhe) cyangwa amavuta ya kaburimbo y'amakara, hamwe n'uburyo bwo kugenzura umwanda cyane.
• Uburyo: Bikubiyemo gutunganya mbere y’uko ibintu fatizo bitunganywa, guteka bitinze, no gukaranga ubushyuhe bwinshi cyane (1.200–1.400°C), bigatuma uduce duto twa karuboni twiganjemo cyane dukora imiterere y’udusimba.
• Igiciro: Uburyo bugoye bwo gukora bufite ibiciro bikubye inshuro nyinshi ugereranyije na koka isanzwe ya peteroli, ariko butanga umusaruro mwiza cyane.

II. Ingaruka ku bwiza bw'amashanyarazi

Uburyo bwo kuyobora amashanyarazi

• Peteroli Coke: Ifite ubushobozi bwo guhangana n’ibintu byinshi, iterwa cyane n’imyanda (urugero: sulfur, vanadium). Coke ifite sulfure nyinshi ikora oxyde gaseous mu gihe cy’amashanyarazi, bigatera umwanda w’ibidukikije no kugabanuka k’ubushobozi bwo gutwara ibintu.
• Ifu ya Needle Coke: Ingufu nke zo gupima ubuziranenge hakoreshejwe ifu, zituma habaho imikorere myiza y'amashanyarazi, ingufu zikoreshwa kugabanuka, kandi zigatuma ingufu zikoreshwa neza.

Ubudahangarwa bw'ubushyuhe n'ubudahangarwa bw'umwuka

• Peteroli Coke: Ingufu nyinshi zo kwaguka k'ubushyuhe (CTE), zishobora kwangirika mu gihe cy'ubushyuhe bwinshi, kandi zidashobora kurwanya ogisijeni neza, bigatuma ikoreshwa ry'amashanyarazi ryihuta.
• Ifu ya Needle Coke: CTE nkeya kandi irwanya cyane ubushyuhe, ikomeza kutagira ingaruka ku bushyuhe burenga 3,000°C kandi ikongera igihe cyo kubaho cya electrode.

Imbaraga za mekanike n'ubudahangarwa bwa ruswa

• Peteroli Coke: Ingufu nke z'uduce, zishobora gucikamo ibice mu buryo bwa cryolite bukabije, bigatuma ikoreshwa ry'ibinyabutabire rirushaho kwiyongera.
• Ifu ya Needle Coke: Imiterere ya fibre igabanya ubukana bw'imihangayiko, igatanga ubudahangarwa budasanzwe ku gushwanyagurika kwa mekanike, ikaba ari nziza cyane mu bidukikije bikomeye nko gukora ibyuma bikoresha amashanyarazi menshi.

Kugenzura umwanda no guhuza ibicuruzwa

• Peteroli Coke: Ihindagurika ryinshi mu bipimo by'umwanda (urugero, Ni, V, Ca), rituma habaho uburyo bwo gukabya okiside ya anode, rigatuma imikorere ya electrode ihungabana kandi rigagabanya imikorere ya electrolysis ya aluminiyumu.
• Ifu ya Needle Coke: Isuku nke cyane igerwaho binyuze mu gusya amazi menshi no gukaraba neza, bigatuma ibicuruzwa bihora bihindagurika mu gukora electrode nziza.

III. Gukoresha n'agaciro k'ubukungu

Coke ya Peteroli

• Ikoreshwa ry'ibanze: Ibicanwa by'inganda (urugero: amatanura ya sima, amatanura y'ibirahure), ibikoresho bya karuboni byo mu rwego rwo hasi (urugero: electrodes z'ibanze za grafiti, paste ya anode).
• Imbogamizi: Isoko rya koke ifite sulfure nyinshi riragabanuka bitewe n'amabwiriza agenga ibidukikije, ridakwiriye gukoreshwa mu buryo bworoshye.

Koka y'urushinge

• Ikoreshwa ry'ingenzi: Agaciro k'ubukungu: Igiciro cyacyo kiri hejuru y'inshuro 5-10 ugereranyije na koke isanzwe ya peteroli, hamwe n'ubwiyongere bw'abakenera buterwa n'iterambere mu ikoranabuhanga rishya ry'ingufu.
• Electrode za grafiti zifite imbaraga nyinshi cyane: Zifite agaciro karenze 60% by'ibikenewe byose bya coke y'inshinge, ni ingenzi cyane mu gukora ibyuma by'amashanyarazi byo mu itanura.
• Anode za bateri ya lithium-ion zo mu rwego rwo hejuru: Imiterere y’ibice n’ubugari bwa kristali byoroshya ikwirakwira rya lithium-ion, bikongera imikorere myiza ya bateri yo gushyushya no gusohora umuriro.
• Ibikoresho byihariye bya grafiti: Nk'ibikoresho bya grafiti bya kirimbuzi n'ibikoresho bya grafiti bikoresha ubushyuhe bwinshi.

IV. Ingendo n'imbogamizi mu nganda

Koke y'urushinge:

• Kwagura byihuse ubushobozi bw'ibicuruzwa mu gihugu (biteganijwe ko ubushobozi bwa koke ikoresha peteroli buzaba bugeze kuri toni miliyoni 2.21 ku mwaka mu 2023), nubwo hagikomeje kwishingikiriza ku bicuruzwa bitumizwa mu mahanga bigura ibikomoka ku mavuta. Iterambere mu ikoranabuhanga riracyari ingenzi.

Koka ya Peteroli:

• Amasoko yo mu rwego rwo hagati kugeza ku rwego rwo hasi ahura n’ibibazo by’ibidukikije, bigasaba ko ubuziranenge bukomeza gukoreshwa binyuze mu buryo bwa tekiniki mbere yo guhuza (urugero, kuvanga ibikoresho fatizo biva ahantu hatandukanye). Ariko, ntabwo ishobora gusimbura inshinge za koka mu buryo bworoshye.
