Vuba aha, bitewe n’ibiciro by’inganda zishyushye, ibiciro bya peteroli byo mu gihugu byazamuye izamuka rya kabiri muri uyu mwaka. Ku ruhande rw’ibicuruzwa, ibicuruzwa bya peteroli bitumizwaga mu mahanga byari bike muri Nzeri, umusaruro w’ibicuruzwa bya peteroli wongeye kugabanuka ugereranije n’uko byari byitezwe, kandi umusaruro w’ibicuruzwa bya peteroli byongeye kugabanuka uherutse kugabanuka. Ku ruhande rwo hejuru, umutungo w’ibicuruzwa bya peteroli byongewemo peteroli wo ...
Vuba aha, bitewe n’ibikenewe mu nganda, igiciro cya petcoke mu gihugu cyazamuye cyane ku nshuro ya kabiri uyu mwaka. Ku ruhande rw’ibicuruzwa, ingano ya peteroli ya coke itumizwa mu mahanga muri Nzeri yari nto, kandi ingano y’ibicuruzwa bya peteroli ya coke mu gihugu ntiyongeye kuboneka nk’uko byari byitezwe. Byongeye kandi, ingano ya sulfure ya coke muri peteroli mu isuku iherutse yari hejuru, kandi ingano ya coke ya peteroli ya coke ya sulfure nkeya yari nkeya cyane. Ku ruhande rw’ibikenewe, igiciro cya karuboni cya aluminium kirakomeye, kandi ububiko bw’imbeho mu karere k’iburengerazuba bwarafunguwe kimwe ku kindi. Ishami ry’ibikoresho bya anode ryagize uruhare rukomeye mu ikenerwa rya coke ya peteroli ya sulfure nkeya, kandi ingano nyinshi ya coke ya peteroli ya sulfure nkeya yagiye yinjira mu bigo by’ubukorano bya grafiti.
Imbonerahamwe y'ibiciro bya koka ya peteroli ifite sulfur nke mu Burasirazuba bw'Ubushinwa mu 2021
Ukurikije uko ibiciro bya peteroli ya coke ifite sulfur nkeya muri Shandong na Jiangsu bihagaze, igiciro cyo mu ntangiriro za 2021 kizaba hagati ya yuan 1950-2050 kuri toni. Muri Werurwe, bitewe n'ingaruka ebyiri zo kugabanuka kw'itangwa rya peteroli mu gihugu ndetse n'ubwiyongere bw'ubukene, ibiciro bya peteroli mu gihugu byakomeje kuzamuka cyane. By'umwihariko, coke ifite sulfur nkeya yahuye n'impinduka mu bigo bimwe na bimwe. Igiciro cyazamutse kigera kuri RMB 3,400-3500 kuri toni, kigera ku gahigo. Izamuka rya 51% mu munsi umwe. Kuva mu gice cya kabiri cy'umwaka, ibiciro byagiye byiyongera buhoro buhoro bitewe n'ubukene mu bijyanye na karubone ya aluminiyumu na karubone y'icyuma (carburizers, electrodes zisanzwe za grafiti). Kuva muri Kanama, bitewe n'izamuka ry'ibiciro bya peteroli ya coke ifite sulfur nkeya mu majyaruguru y'uburasirazuba bw'u Bushinwa, ubukene bwa coke ifite sulfur nkeya mu rwego rw'ibikoresho bya anode bwimukiye mu Burasirazuba bw'u Bushinwa, byatumye ibiciro bya peteroli ya coke ifite sulfur nkeya byiyongera ku rugero runaka mu Bushinwa bw'Iburasirazuba ku rugero runaka. Kugeza muri iki cyumweru, igiciro cya koke ya peteroli ifite sulfur nkeya muri Shandong na Jiangsu cyazamutse kigera kuri yuan zirenga 4.000 kuri toni, igiciro cyo hejuru cyane, ni ukuvuga ko cyiyongereyeho hagati ya yuan 1950-2100 kuri toni, cyangwa kirenga 100%, uhereye mu ntangiriro z'umwaka.
Ikarita yo gukwirakwiza uduce turi munsi y'uruzi rwa koka yo mu Burasirazuba bw'Ubushinwa
Nkuko bigaragara ku ishusho iri hejuru, kugeza muri iki cyumweru, ku bijyanye n’ikwirakwizwa ry’ibikenewe bya peteroli mu ntara za Shandong na Jiangsu, icyifuzo cya karuboni ya aluminiyumu cyari kigera kuri 38%, icyifuzo cya electrode mbi cyari kigera kuri 29%, naho icyifuzo cya karuboni ya icyuma cyari kigera kuri 22%, naho ibindi bigo bikaba bingana na 11%. Nubwo igiciro cya karuboni ya aluminiyumu ifite sulfur nke muri ako karere cyazamutse kigera kuri yuan zirenga 4.000 kuri toni, urwego rwa karuboni ya aluminiyumu ruracyari ku isonga kubera inkunga yarwo ikomeye. Byongeye kandi, icyifuzo rusange mu ishami rya electrode mbi ni cyiza, kandi ibiciro byemerwa cyane, aho icyifuzo cyabyo kiri hejuru ya 29%. Kuva mu gice cya kabiri cy’umwaka, icyifuzo cy’inganda z’ibyuma zo mu gihugu cyo kongeramo ibyuma cyaragabanutse, kandi igipimo cy’imikorere y’itanura ry’amashanyarazi cyageze kuri 60%, kandi inkunga ya electrode za grafiti ni nke. Kubwibyo, mu buryo bunyuranye, icyifuzo cya karuboni ya aluminiyumu ifite sulfur nke mu ishami rya karuboni yagabanutse cyane.
Muri rusange, inganda zikora peteroli nke za PetroChina zagizweho ingaruka n’umusaruro wa peteroli nke za sulfure ku rugero runaka, kandi umusaruro wazo waragabanutse. Kuri ubu, ibipimo bya peteroli nke za sulfure muri Shandong na Jiangsu birahamye kandi ingano ya sulfure muri rusange igumana 0.5%, kandi ubwiza bwarushijeho kuba bwiza cyane ugereranije n’umwaka ushize. Byongeye kandi, icyifuzo mu turere dutandukanye two munsi y’amazi kiziyongera cyane mu gihe kizaza, bityo mu gihe kirekire, ibura ry’umutungo wa peteroli nke mu gihugu rizaba risanzwe.
