A. kupatsanurwa kwecoke yepetroleum
Mafuta epetroleum coke anogadzirwa nemafuta asina kucheneswa, mafuta anorema uye anoputika nekupisa, anoshandurwa kuita zvigadzirwa, kubva pakuonekwa, coke ine chimiro chisina kurongeka, saizi yebhuroko dema (kana zvidimbu), simbi inopenya, zvidimbu zvecoke zvine maburi, chinhu chikuru chekabhoni, 80wt%. (wt=uremu)

B. kubuda kwecoke yepetroleum
Ruzhinji rwe petroleum coke inogadzirwa muChina ndeye low sulfur coke, iyo inonyanya kushandiswa mukunyungudutsa aruminiyamuuyekugadzirwa kwegirafiti.Imwe yacho inonyanya kushandiswa pazvigadzirwa zvekabhoni, zvakaita seelectrode yegirafiti, anode arc, inoshandiswa pasimbi, simbi dzisina ferrous; Zvigadzirwa zvesilicon zvakakangwa, dzakadai sedzakasiyana-siyanamavhiri ekukuyajecha,bepa rejecha, nezvimwewo; Karubhaidhi yekutengeserana yekugadzira fiber yekugadzira, acetylene nezvimwe zvigadzirwa; Inogona zvakare kushandiswa semafuta, asi painoita mafuta, inofanirwa kushandisa chigayo che impact chakarongwa kuti iite ultrafine grinding. Mushure mekugadzira coke powder kuburikidza nemidziyo, inogona kupiswa. Coke powder inonyanya kushandiswa semafuta mune mamwe mafekitori egirazi uye mafekitori emvura yemarasha.
Sekureva kweNational Bureau of Statistics, huwandu hwemafuta ecoke anogadzirwa neChina muna 2020 hwaive matani mamiriyoni 29.202, zvichikwira ne4.15% pagore, uye kubva muna Ndira kusvika Kubvumbi 2021, huwandu hwemafuta ecoke anogadzirwa neChina hwaive matani mamiriyoni 9.85.
Kugadzirwa kwepetroleum coke muChina kwakanyanya kunowanikwa kumabvazuva kweChina, kuchamhembe kwakadziva kumabvazuva kweChina neSouth China, nekugadzirwa kwakanyanya kunowanikwa kumabvazuva kweChina. Mudunhu rese rekumabvazuva kweChina, dunhu reShandong ndiro rine kugadzirwa kwakanyanya kwepetroleum coke, kwakasvika matani mamiriyoni 10.687 muna 2020. Kubuda kwepetroleum coke mudunhu reShandong hakungori pekutanga kumabvazuva kweChina chete, asiwo kuri pekutanga mumatunhu ese nemaguta muChina, uye kubuda kwepetroleum coke kwakanyanya kupfuura mamwe mapurovhinzi nemaguta.
C. Kupinza nekuburitsa kunze kwecoke yepeturu
China ndeimwe yemakambani makuru anotenga petroleum coke, iyo inonyanya kubva kuUnited States, Saudi Arabia neRussia. Sekureva kweChina Customs, huwandu hwepetroleum coke hunopinzwa munyika yeChina kubva muna 2015 kusvika 2020 hwakaratidza kukwira zvakanyanya. Muna 2019, huwandu hwepetroleum coke hunopinzwa munyika yeChina hwaive matani mamiriyoni 8.267, uye muna 2020, hwaive matani mamiriyoni 10.277, kuwedzera kwe24.31% zvichienzaniswa negore ra2019.
Muna 2020, huwandu hwePetroleum coke inopinzwa muChina hwaive usd 1.002 bhiriyoni, hwakaderera ne36.66% gore negore. Muna 2020, huwandu hwepetroleum coke inopinzwa kunze hwakasvika pakakwirira, asi kukosha kwepetroleum coke inopinzwa kunze kwakadzikira. Sezvo hupfumi hwepasi rose hwakakanganiswa zvakanyanya nedenda reCOVID-19, mutengo wepetroleum coke mumusika wepasi rose wakadzikirawo, izvo zvakakurudzira kupinza petroleum coke muChina uye zvakawedzera huwandu hwepetroleum coke inopinzwa kunze, asi zvakaderedza huwandu hweinopinzwa kunze.
Sekureva kwedata reChina Customs, kutengeswa kwemafuta epetroleum coke kuChina kwakaratidza kudzikira, kunyanya muna 2020 nekuda kweCOVID-19, kutengeswa kwemafuta epetroleum coke kuChina kwakadzikira zvakanyanya, pakasvika 2020, kutengeswa kwemafuta epetroleum coke kuChina kwakadzikira kusvika pamamiriyoni 1.784 emadhora, kudzikira kwegore negore kwe22.13%; Kukosha kwezvinhu zvakatengeswa kunze kwenyika kwaive $459 miriyoni, kudzikira ne38.8% gore rega rega.
D. Mafambiro ekufambira mberi kweindasitiri yemafuta ecoke
Mukufamba kwenguva, musika wepetroleum coke uchiri kuzara nezvinhu zvakawanda zvisingazivikanwe, uye maitiro ekuwanikwa uye kudiwa kwepetroleum coke achiri kutarisana nematambudziko akawanda. Kubva pamaonero ehuwandu hwezvinhu, munguva pfupi, nekuda kwekunonoka kwekuendeswa kwemafuta akasara ehydrogenation, kunonoka kuendeswa kwemidziyo yecoking kuchiri chinangwa chikuru. Mukufamba kwenguva, divi rekupihwa kwepetroleum coke richaganhurirwawo nekuchengetedzwa kwezvakatipoteredza, mitemo nezvimwe zvinhu, uye kucharamba kuripo matekinoroji matsva uye zvimwe zvinotsiva zvakatipoteredza. Mutemo wekuchengetedza zvakatipoteredza uri kuva wakajairika zvishoma nezvishoma, uye kugadzirwa hakugone kuganhurirwa kuti pave nekubuda kwemhepo kwakaderera zvakanyanya. Nekuvandudzwa kwemidziyo yekudzivirira zvakatipoteredza yemakambani, kukanganisa kwemutemo wekuchengetedza zvakatipoteredza pamusika kuchaderera, uye pesvedzero yehukama hwekugovera nezvinodiwa pamusika uye mutengo wekutenga zvinhu zvemabhizinesi zvichawedzerwa.
Kudivi rekuda, indasitiri yepetroleum coke iri pasi icharamba ichiunza matambudziko akasiyana-siyana ehupfumi, zvinhu zvine chekuita nemutemo, mabhizinesi e electrolytic aluminium ari pasi pe alumina, mutengo wemagetsi, mutengo wakakwira wekuwana purofiti, saka makambani emangwana ealuminium ane cheni yakazara yeindasitiri ine purofiti yakakura, sezvo marongerwo emusika wealuminium achichinja zvishoma nezvishoma, pakati penyika achatamisa simba zvishoma nezvishoma, Izvi zvichakanganisa maitiro nekukura kwemusika weanode yakabikwa kare uye musika wekabhoni mune ramangwana.
Munguva yepakati nerefu, mamiriro ehupfumi hwenyika, mitemo yenyika, chimiro chekugovera zvigadzirwa, shanduko yezvinhu, mitengo yezvinhu zvisina kugadzirwa, kushandiswa kwemafuta, njodzi, nezvimwewo, zvinogona kuve zvinhu zvinotungamira zvinokanganisa musika wemafuta ecoke pamatanho akasiyana. Naizvozvo, mabhizinesi anofanira kuongorora mamiriro aripo eindasitiri yemafuta ecoke, kudzidza zvakawanda nezvemitemo yakakodzera munyika nekune dzimwe nyika, kufanotaura nzira yekuvandudza musika wemafuta ecoke mune ramangwana, kudzivirira njodzi nenguva, kushandisa mikana, shanduko nenguva uye hunyanzvi, ndiyo mhinduro yenguva refu.
