Intshayelelo kwi-petroleum coke
I-petroleum coke yi-distillation yokwahlula ii-oyile ezikhanyayo nezinzima, i-oyile enzima ijika ibe yimveliso yokugqibela ngenkqubo yokuqhekeka kobushushu. Jonga ngokubonakala kwayo, i-coke ayilunganga kwimilo kunye nobukhulu beengqumba ezimnyama (okanye amasuntswana) ukukhazimla kwesinyithi; ii-coke particles zinesakhiwo esinemingxuma, izinto eziphambili yi-carbon, zine-80wt% ngaphezulu, okuseleyo yi-hydrogen, i-oxygen, i-nitrogen, i-sulfur kunye nezinto zesinyithi. Iipropati zeekhemikhali ze-petroleum coke ezineempawu zayo zomzimba nezekhemikhali ezikhethekileyo kunye neepropati ze-mechanical. I-non-votile carbon eyinxenye yobushushu bayo, i-volatile matter kunye nokungcola kweeminerali (i-sulfur, ii-metal compounds, amanzi, uthuthu, njl.njl.), zonke ezo mpawu zimisela iipropati zeekhemikhali ze-coke.
I-coke yenaliti:Inesakhiwo senaliti esicacileyo kunye nobume befayibha, uninzi lwayo lusetyenziswa njenge-electrode yegrafiti enamandla aphezulu ekwenzeni intsimbi. Kwi-needle coke inemfuneko engqongqo yomgangatho kwi-sulfur content, ash content, volatile kunye ne-true density njl.njl., ukuze kubekho iimfuno ezikhethekileyo zobugcisa bokucubungula i-needle coke kunye nezinto eziluhlaza.
I-sponge coke:ukusebenza kweekhemikhali okuphezulu, umxholo ophantsi wokungcola, osetyenziswa kakhulu kwishishini le-aluminiyam nakwishishini lekhabhoni.
I-Shot coke okanye i-globular coke:imilo eyingqukuva ye-cylindrical, ububanzi obuyi-0.6-30mm, edla ngokuveliswa yintsalela ye-asphalt ephezulu ene-sulfur, ingasetyenziselwa kuphela ukuvelisa umbane, isamente kunye nezinye izibaso zoshishino.
I-powder coke:Iveliswe ngokusebenzisa ukucubungula okucoliweyo, amasuntswana alungile (ububanzi be-0.1-0.4mm), i-volatible ephezulu kunye ne-thermal expansion coefficient yenza ukuba ingasetyenziswa ngokuthe ngqo kwi-electrodes nakwishishini le-carbon.
Ukusetyenziswa kwePetroleum coke
Eyona ndawo iphambili esetyenziswa kuyo i-petroleum coke eTshayina yi-electrolytic aluminium industry, ebanga ngaphezu kwe-65% yexabiso lilonke le-petroleum coke. Ilandelwa yi-carbon, i-silicon yemizi-mveliso kunye neminye imboni yokunyibilikisa. I-petroleum coke isetyenziswa kakhulu njengepetroli kwisamente, ekuveliseni umbane, kwiglasi nakwamanye amashishini, ibandakanya isiqingatha esincinci. Okwangoku, ukubonelela kunye nemfuno ye-petroleum coke yasekhaya iyafana. Nangona kunjalo, ngenxa yokuthunyelwa kwamanye amazwe kwenani elikhulu le-petroleum coke ene-sulfur ephantsi, ukubonelela okupheleleyo kwe-petroleum coke yasekhaya akwanelanga, kwaye i-petroleum coke ene-sulfur ephakathi nephezulu kufuneka ingeniswe ukuze yongezwe. Ngokwakhiwa kwenani elikhulu lee-coking units kwiminyaka yakutshanje, imveliso ye-petroleum coke yasekhaya iya kuphuculwa kwaye yandiswe.
①Ishishini leglasi lishishini elisebenzisa amandla amaninzi. Iindleko zalo zepetroli zimalunga ne-35% ~ 50% yeendleko zeglasi. Isithando seglasi sisixhobo esisebenzisa amandla amaninzi kumgca wokuvelisa iglasi. ② Nje ukuba isithando seglasi sitshiswe, asinakuvalwa de isithando sihlaziywe (iminyaka emi-3-5). Ke ngoko, amafutha kufuneka ongezwe rhoqo ukuqinisekisa ubushushu besithando bube ngamawaka eedigri kwisithando. Ke ngoko, indawo yokusebenzela yokucola ngokubanzi iya kuba neemill ezimisiweyo ukuqinisekisa ukuveliswa okuqhubekayo. ③ Umgubo we-coke wepetroleum usetyenziswa kwishishini leglasi, kwaye ubuncinci bufuneka bube yi-200 mesh D90. ④ Umxholo wamanzi we-coke eluhlaza ngokubanzi yi-8% - 15%, kwaye kufuneka yomiswe ngaphambi kokuba ingene kwisithando. ⑤ Okukhona umxholo wokufuma wemveliso egqityiweyo uphantsi, kokukhona kungcono. Ngokubanzi, isiphumo sokuphelelwa ngamanzi kwenkqubo yesekethe evulekileyo singcono.
