A. petroleum coke classification
Petroleum coke is crude oil distillation ichave yakareruka uye inorema mafuta kupatsanurwa, mafuta anorema uyezve kuburikidza nekuita kwekupwanya kunopisa, kushandurwa kuita zvigadzirwa, kubva pakuonekwa, coke yechimiro chisina kujairika, saizi yeblack block (kana zvimedu), metallic luster, coke zvimedu zvine porous chimiro, chikuru chinhu chinoumbwa kabhoni, Bata 80wt%. (wt = uremu)
Maererano nekugadzirisa nzirainogona kukamurwa kuitacoke mbishiuyecoke yakabikwa. Iyo yekutanga inowanikwa necoke tower yeyakanonoka coking mudziyo, inozivikanwawo seoriginal coke; Iyo yekupedzisira inogadzirwa ne calcination (1300 ° C), inozivikanwawo secalcined coke.
Maererano nesarufa yemukati, inogona kukamurwa kuitahigh sulfur coke(sarufa yemukati inodarika4%), pakati sarufa coke(sarufa yemukati ndeye2%-4%) uyepasi sarufa coke(sarufa yemukati ishoma pane2%).
Zvinoenderana neyakasiyana microstructure, inogona kukamurwa kuitachipanje cokeuyetsono coke. Iyo yekare porous se spongy, inozivikanwawo secommon coke. Iyo yekupedzisira dense sefibrous, inozivikanwawo secoke yemhando yepamusoro.
Maererano nemhando dzakasiyanainogona kukamurwa kuitatsono coke, projectile coke or spherical coke, chipanje coke, poda cokemarudzi mana.
B. petroleum coke kubuda
Mazhinji epetroleum coke inogadzirwa kuChina ndeye low sulfur coke, iyo inonyanya kushandiswa mualuminium kunyungudukauyekugadzira magirafu.Imwe yacho inonyanya kushandiswacarbon products, zvakaita segraphite electrode, anode arc, kushandiswa kwesimbi, simbi dzisina-ferrous; Carbonized silicon zvigadzirwa, zvakadai zvakasiyana-siyanakugaya mavhiri, jecha,sand paper, nezvimwewo; Commercial calcium carbide yekugadzirwa kwefiber synthetic, acetylene uye zvimwe zvigadzirwa; Inogona zvakare kushandiswa sehuni, asi pakuita mafuta, inoda kushandisa giredhi yekukanganisa chigayo kuita ultrafine kugaya. Mushure mekugadzira coke powder kuburikidza nemidziyo, inogona kupiswa. Iyo coke poda inonyanya kushandiswa sehuni mune mamwe mafekitori egirazi uye marasha emvura slurry zvidyarwa.
Sekureva kweNational Bureau of Statistics, China petroleum coke yakabuda muna 2020 yaive 29.202 miriyoni matani, yakakwira 4.15% gore negore, uye kubva muna Ndira kusvika Kubvumbi 2021, kuChina petroleum coke kubuda kwaive 9.85 miriyoni matani.
Kugadzirwa kwepetroleum coke muChina kunonyanya kutariswa kumabvazuva kweChina, kuchamhembe kwakadziva kumabvazuva kweChina neSouth China, ine kugadzirwa kwakanyanya kumabvazuva kweChina. Munharaunda yese yekumabvazuva kweChina, purovhinzi yeShandong ine yakanyanya kugadzirwa kwepetroleum coke, iyo yakasvika 10.687 miriyoni matani muna 2020. Kubuda kwepetroleum coke mudunhu reShandong hakungori pekutanga kumabvazuva kweChina, asiwo kunotanga mumatunhu ese nemaguta. muChina, uye kubuda kwepetroleum coke kwakakwirira zvikuru kupfuura mamwe mapurovhinzi nemaguta.
C. Petroleum coke import and export
China ndeimwe yevanotengesa zvikuru petroleum coke, iyo inonyanya kubva kuUnited States, Saudi Arabia neRussia. Zvinoenderana nedata reChina Customs, huwandu hwekupinza petroleum coke muChina kubva 2015 kusvika 2020 hwakaratidza kukwira kumusoro. Muna 2019, vhoriyamu yepetroleum coke muChina yaive 8.267 miriyoni matani, uye muna 2020, yaive 10.277 miriyoni matani, kuwedzera kwe24.31% zvichienzaniswa ne2019.
Muna 2020, huwandu hwekupinza kwePetroleum coke muChina hwaive USd 1.002 bhiriyoni, zvichidzika ne36.66% gore negore. Muna 2020, huwandu hwekupinzwa kunze kwepetroleum coke hwakasvika pakakwirira, asi kukosha kwekupinza kwepetroleum coke kwakadzikira. Sezvo hupfumi hwepasi rose hwarohwa zvakanyanya nedenda reCCIDID-19, mutengo wepetroleum coke mumusika wepasi rose wadonhawo, izvo zvakurudzira kutengwa kwepetroleum coke kuChina uye kuwedzera huwandu hwekupinza kwepetroleum coke, asi zvakaderedza import amount.
Sekureva kwedhata reChina Customs, kuChina petroleum coke kutengesa kunze kwakaratidza kuderera, kunyanya muna 2020 nekuda kwekukanganisa kweCCIDID-19, kuChina petroleum coke kutengesa kunze kwakadzikira zvakanyanya, panosvika 2020, kuChina kwepetroleum coke kutengesa kunze kwakadzikira kusvika 1.784 miriyoni yemadhora, a gore negore kuderera kwe22.13%; Kukosha kwekutengesa kunze kwenyika kwaive $459 miriyoni, pasi ne38.8% gore pagore.
D. Kuvandudza maitiro e petroleum coke industry
Nekufamba kwenguva, musika wepetroleum coke uchiri wakazara nekusagadzikana kwakawanda, uye kupa uye kudiwa kwemaitiro epetroleum coke kuchiri kutarisana nematambudziko mazhinji. Kubva pakuona kwesimba rekugadzirisa, munguva pfupi, nekuda kwekunonoka kuburitsa kweasara oiri hydrogenation simba, kunonoka coking mudziyo kuendesa ichiri kutungamira kukuru. Nekufamba kwenguva, rutivi rwekugovera petroleum coke ruchadzorwawo nekuchengetedzwa kwezvakatipoteredza, marongero nezvimwe zvinhu, uye pacharamba paine matekinoroji matsva uye mamwe anotsiva ane hushamwari. Gwaro rekuchengetedzwa kwezvakatipoteredza riri kuita zvakajairika, uye kugadzirwa hakugone kuganhurirwa kuwana ultra-low emissions. Nekuvandudzwa kwemabhizinesi ega ekuchengetedza nharaunda, kukanganisa kwemutemo wekuchengetedza kwezvakatipoteredza pamusika kuchaderedzwa, uye pesvedzero yekupa musika uye hukama hwekuda uye mutengo wekutenga zvinhu zvemabhizinesi uchawedzerwa.
Demand side, petroleum coke downstream industry icharamba ichiunza matambudziko akasiyana-siyana ehupfumi, mitemo yezvinhu, electrolytic aluminium enterprises ikozvino iri pasi pealuminium, mutengo wemagetsi, mutengo wakakwira kuti uve nepurofiti yekutaura nezvayo, saka makambani ealuminium emangwana ane indasitiri yakazara cheni ine purofiti yakakura, sezvo iyo aluminium musika dhizaini ichachinja zvishoma nezvishoma, nechepakati ichaendesa zvishoma nezvishoma kugona, Ichakanganisa pateni uye kusimudzira kweyakabikwa anode musika uye kabhoni musika mune ramangwana.
Munguva yepakati uye kureba, nharaunda yehupfumi, mitemo yeindasitiri yenyika, chimiro chekugovera zvigadzirwa, shanduko yezvinyorwa, mitengo yezvigadzirwa, kudzika kwemvura kudyiwa, emergency, nezvimwewo, zvinogona kunge zviri izvo zvinotungamira zvinokanganisa musika wemafuta coke pamatanho akasiyana. Naizvozvo, mabhizinesi anofanirwa kuongorora mamiriro eiyo petroleum coke indasitiri, kudzidza zvakawanda nezve akakodzera marongero kumba nekune dzimwe nyika, kufanotaura ramangwana rekusimudzira kwemusika wepetroleum coke, kudzivirira njodzi panguva, kubata mikana, shanduko nenguva uye hunyanzvi, inguva refu. mhinduro.
