Mu mpera za 2022, igiciro cya koka itunganywa muri peteroli ku isoko ry’imbere mu gihugu cyaragabanutse cyane. Itandukaniro ry’ibiciro hagati y’inganda zimwe na zimwe zikora ubucuruzi bw’ibikomoka kuri peteroli n’inganda zikora ubucuruzi bw’ibikomoka kuri peteroli zo mu gace ni rinini cyane.
Dukurikije imibare n'isesengura rya Longzhong Information, nyuma y'Umunsi Mushya w'Ubunani, ibiciro bya peteroli bya koka byo mu gihugu byose byaragabanutse cyane, kandi ibiciro by'ibikorwa ku isoko byaragabanutseho 8-18% buri kwezi.
Koka ya sulfur nkeya:
Koke yo mu bwoko bwa sarufa nke mu ruganda rutunganya ibikomoka kuri peteroli mu majyaruguru y'uburasirazuba rwa PetroChina ahanini yashyize imbere ubwishingizi mu kugurisha mu Ukuboza. Nyuma y'uko igiciro cy'ubwishingizi gitangajwe mu mpera z'Ukuboza, yagabanutseho 500-1100 yuan/toni, hamwe n'igabanuka rya 8.86%. Mu isoko ry'Amajyaruguru y'Ubushinwa, koke yo mu bwoko bwa sarufa nke yoherejwe mu bubiko, kandi igiciro cy'ubucuruzi cyaragabanutse bitewe n'isoko. Kohereza koke ya peteroli mu nganda zitunganya ibikomoka kuri peteroli muri CNOOC Limited byari biciriritse, kandi amasosiyete yo mu nkengero z'ubutaka yari afite imyumvire ikomeye yo gutegereza no kureba, kandi ibiciro bya koke mu nganda zitunganya ibikomoka kuri peteroli byaragabanutse.
Koka ya sulfur iringaniye:
Uko igiciro cya peteroli cya koke ku isoko ry’iburasirazuba cyakomeje kugabanuka, kohereza koke ifite sulfure nyinshi mu majyaruguru y’uburengerazuba bwa PetroChina byari biri munsi y’umuvuduko. Umuzigo ni Yuan 500 kuri toni, kandi umwanya wo gucuruza koke ku masoko y’iburasirazuba n’iburengerazuba waragabanutse. Kohereza koke ya peteroli ya Sinopec wagabanutseho gato, kandi amasosiyete yo mu nkengero z’ubutaka muri rusange ntashishikajwe no kuzuza. Ibiciro bya Coke mu nganda zitunganya inzoga bizakomeza kugabanuka, kandi igiciro cyo kugura cyagabanutseho Yuan 400-800.
Mu ntangiriro za 2023, umusaruro wa peteroli uzakomeza kwiyongera. PetroChina Guangdong Petrochemical Co. Igipimo cy'umusaruro ku mwaka cyariyongereyeho 1.12% ugereranije n'uwabanjirije Umunsi Mukuru w'Ubunani. Dukurikije ubushakashatsi ku isoko n'imibare bya Longzhong Information, muri Mutarama, nta gutinda guteganyijwe mu ifungwa ry'ibikoresho byo guteka mu Bushinwa. Umusaruro wa peteroli uturuka muri peteroli ushobora kugera kuri toni miliyoni 2.6 buri kwezi, kandi toni miliyoni 1.4 z'umutungo wa peteroli uturuka mu mahanga wageze mu Bushinwa. Muri Mutarama, umusaruro wa peteroli uracyari ku rwego rwo hejuru.
Igiciro cya peteroli ya coke ifite sulfure nke cyaragabanutse cyane, kandi igiciro cya coke ifite calcium yagabanutseho gato ugereranyije n’iy’ibikoresho fatizo. Inyungu y’ishingiro ya coke ifite calcium ya sulfure nke yazamutseho gato Yuan 50 kuri toni ugereranije n’iyabanjirije iserukiramuco. Ariko, isoko rya electrode ya grafiti rikomeje kuba rito mu bucuruzi, umutwaro w’inganda z’ibyuma wakomeje kugabanuka, kandi icyifuzo cya electrode za grafiti kiri hasi. Igipimo mpuzandengo cy’ubushobozi bwo gukoresha ibyuma bikoreshwa mu gukora ibyuma by’amashanyarazi bya arc furnace ni 44.76%, bingana na 3.9% munsi y’ibyabanjirije iserukiramuco. Inganda z’ibyuma ziracyari mu gihombo. Haracyari inganda ziteganya guhagarika umusaruro kugira ngo ziwusane, kandi inkunga y’isoko ry’ibikoresho ntabwo ari nziza. Cathodes za grafiti zigurwa igihe cyose zikenewe, kandi isoko muri rusange rishyigikiwe n’ibikenewe cyane. Biteganijwe ko igiciro cya coke ifite calcium ya sulfure nke gishobora kugabanuka mbere y’iserukiramuco ry’impeshyi.
Ubucuruzi ku isoko rya peteroli rya calcium carbonate riciriritse ni ubuciriritse, kandi amasosiyete ashyira imbere cyane amategeko n'amasezerano yo gukora no kugurisha. Bitewe n'igabanuka rikomeje ry'igiciro cya peteroli, igiciro cyashyizweho umukono cya calcium carbonate cyagabanijweho Yuan 500-1000/toni, kandi inyungu y'ibigo yagabanutse igera kuri Yuan 600/toni, ari 51% munsi y'iyabanjirije iserukiramuco. Ibiciro bishya byo kugura anode zatetse byaragabanutse, igiciro cya aluminium electrolytic terminal spot cyakomeje kugabanuka, kandi ubucuruzi ku isoko rya aluminium carbone bwabaye buke gato, budafite inkunga ihagije yo kohereza neza isoko rya peteroli rya carbonate.
Iteganyagihe:
Nubwo hari ibigo bimwe na bimwe biri inyuma y’amazi bifite imyumvire yo kugura no kubika ibintu hafi y’Iserukiramuco ry’Impeshyi, bitewe n’ubwinshi bw’umutungo wa peteroli wo mu gihugu hamwe n’uko umutungo winjizwa mu mahanga ukomeza kuzura muri Hong Kong, nta kintu na kimwe kigaragara gishimishije kirimo ku isoko ry’ibikomoka kuri peteroli byoherezwa mu gihugu. Inyungu ku musaruro w’ibigo biri inyuma y’amazi ya karuboni yagabanutse, kandi bimwe mu bigo byitezweho kugabanya umusaruro. Isoko rya nyuma riracyari kuganjemo ibikorwa bidakomeye, kandi biragoye kubona inkunga ku biciro bya peteroli. Biteganijwe ko mu gihe gito, ibiciro bya peteroli mu nganda zitunganya peteroli bizahindurwa cyane kandi bigahinduka mu buryo buhamye. Inganda zitunganya peteroli zifite umwanya muto wo guhindura ibiciro bya peteroli hashingiwe ku ishyirwa mu bikorwa ry’amabwiriza n’amasezerano.
