Ingano ya koke ifite imiterere isa n'urushinge kandi ikozwe muri peteroli y'urushinge iva mu nganda zitunganya cyangwa mu icupa rya kaburimbo. Ni yo mashini nyamukuru ikoreshwa mu gukora electrode za grafiti zikoreshwa mu gukora ibyuma hakoreshejwe itanura ry'amashanyarazi (EAF). Iri sesengura ry'isoko rya koke rya koke rireba ibyagurishijwe n'inganda za grafiti, inganda za bateri, n'izindi. Isesengura ryacu rireba kandi ku igurishwa rya koke ya gaburinge muri APAC, mu Burayi, muri Amerika ya Ruguru, muri Amerika y'Epfo, na MEA. Mu 2018, igice cy'inganda za grafiti cyari gifite isoko rinini, kandi iyi gahunda yitezweho gukomeza mu gihe giteganyijwe. Ibintu nko kwiyongera k'ubusabe bwa electrode za grafiti mu buryo bwa EAF bwo gukora ibyuma bizagira uruhare runini mu gice cy'inganda za grafiti kugira ngo bigumane umwanya wabyo ku isoko. Nanone, raporo yacu ku isoko rya koke ya koke ku isi ireba ibintu nko kwiyongera k'ubushobozi bwo gutunganya peteroli, kwiyongera k'uburyo bwo gukoresha imodoka zidafite ibidukikije, kwiyongera k'ubusabe bwa electrode za grafiti za UHP. Ariko, imbogamizi zo kwiyongera kw'icyuho mu bucuruzi bwa lithiamu n'umusaruro w'ibikomoka ku mashanyarazi zigaragara mu gushora imari mu nganda z'amakara bitewe n'amabwiriza arwanya ihumana rya karuboni, ihindagurika ry'ibiciro bya peteroli n'amakara bishobora kubangamira iterambere ry'inganda zikora inzoga za “needle coke” mu gihe giteganyijwe.
Isoko ry'Isi rya Needle Coke: Incamake
Ubukene bw'amashanyarazi ya UHP grafiti buri kwiyongera
Electrode za grafiti zikoreshwa mu bikorwa, nko mu matanura y’amazi n’amatanura yo mu mazi kugira ngo hakorwe ibyuma, ibikoresho bitari iby’icyuma, n’ibyuma. Zikoreshwa cyane cyane muri EAFs mu gukora ibyuma. Electrode za grafiti zishobora gukorwa hakoreshejwe peteroli coke cyangwa needle coke. Electrode za grafiti zishyirwa mu byiciro by’ingufu zisanzwe, ingufu nyinshi, imbaraga nyinshi cyane, na UHP hashingiwe ku bipimo nko kurwanya, gutwara amashanyarazi, gutwara ubushyuhe, kurwanya oxidation n’ihungabana ry’ubushyuhe, hamwe n’imbaraga za mekanike. Mu bwoko bwose bwa electrode za grafiti, electrode za grafiti za UHP zirimo kwitabwaho mu nganda z’ibyuma. Uku gukenera electrode za UHP bizatuma isoko ry’isi yose rya needle coke ryaguka ku kigero cya 6% mu gihe cy’iteganyagihe.
Kugaragara kw'icyuma cy'icyatsi kibisi
Ibyuka bya CO2 bihumanya ikirere ni ikibazo gikomeye inganda zikora ibyuma ku isi zihanganye nacyo. Kugira ngo iki kibazo gikemuke, hakozwe ibikorwa byinshi by’ubushakashatsi n’iterambere (R&D). Ibi bikorwa by’ubushakashatsi n’iterambere byatumye habaho icyuma kibisi. Abashakashatsi bavumbuye uburyo bushya bwo gukora ibyuma bushobora gukuraho burundu ibyuka bya CO2 bihumanya ikirere. Mu buryo busanzwe bwo gukora ibyuma, mu gihe cyo gukora ibyuma, umwotsi mwinshi, karubone, n’umuriro ushyushye birarekurwa. Uburyo busanzwe bwo gukora ibyuma busohora CO2 inshuro ebyiri z’uburemere bw’icyuma. Ariko, uburyo bushya bushobora gukora ibyuma nta byuka bihumanya ikirere bihumanya ikirere. Ikoranabuhanga ryo gufata no kubika amakara n’ikarubone (CCS) riri muri byo. Iri terambere ryitezweho kugira ingaruka nziza ku iterambere rusange ry’isoko.
Imiterere y'ubutaka ihanganye
Kubera ko hari abakinnyi bake bakomeye, isoko rya needle coke ku isi ririmo kwibanda cyane. Iri sesengura rikomeye ry’abacuruzi rigamije gufasha abakiriya kunoza aho bahagaze ku isoko, kandi hakurikijwe ibi, iyi raporo itanga isesengura rirambuye ry’inganda nyinshi zikomeye zikora needle coke, zirimo C-Chem Co. Ltd., GrafTech International Ltd., Mitsubishi Chemical Holdings Corp., Phillips 66 Co., Sojitz Corp., na Sumitomo Corp.
Nanone, raporo y'isesengura ry'isoko rya needle coke ikubiyemo amakuru ku bigiye kuba n'imbogamizi zizagira ingaruka ku iterambere ry'isoko. Ibi bigamije gufasha amasosiyete gushyira ingamba no kubyaza umusaruro amahirwe yose yo gukura mu gihe kiri imbere.
