Ulwazi lwepetroleum coke kunye necalcined petroleum coke
1. I-petroleum coke
I-petroleum coke yimveliso yepetroleum emnyama okanye emnyama eqinileyo enentsimbi ecwebezelayo kwaye inamarhashalala.Amacandelo e-petroleum coke yi-hydrocarbons, equkethe i-90-97% yekhabhoni, i-1.5-8% ye-hydrogen, i-nitrogen, i-chlorine, i-sulfure kunye ne-heavy metal compounds.
I-petroleum coke yimveliso ye-pyrolysis ye-feedstock oil kwi-coking units ezilibaziseka kumaqondo aphezulu okushisa ukuvelisa iimveliso ze-oyile ezilula.Imveliso yepetroleum coke imalunga ne-25-30% yeoli eluhlaza.Ixabiso layo le-calorific eliphantsi li malunga ne-1.5-2 ngamaxesha amalahle, umxholo womlotha awukho ngaphezu kwe-0.5%, into eguqukayo malunga ne-11%, kwaye umgangatho usondele kwi-anthracite.
2. Umgangatho womgangatho wepetroleum coke
Icoke yepetroleum ilibazisekile ibhekisa kwicoke eluhlaza eveliswe yiyunithi yokupheka ilibazisekile, eyaziwa ngokuba yicoke eqhelekileyo, kwaye akukho mgangatho uhambelanayo wesizwe okwangoku.Okwangoku, amashishini emveliso yasekhaya ikakhulu avelisa ngokwemigangatho yoshishino iSH0527-92 eyenziwe yiSinopec Corporation yangaphambili.Umgangatho uhlelwa ngokukodwa ngokwe-sulphur content ye-petroleum coke.Phakathi kwazo, i-coke yeklasi yokuqala kunye neNombolo ye-1 ifanelekile ukwenza i-electrode ye-graphite yamandla aqhelekileyo kwi-industry ye-steelmaking, kwaye ifanelekile kwikhabhoni ye-aluminium kwishishini lokwenza i-aluminium;No. 2 coke isetyenziswa kwishishini lokwenza aluminiyam.I-Electrode paste esetyenziswa kwiiseli ze-electrolytic (isithando somlilo) kunye nokuveliswa kwee-electrode zegraphite, inombolo ye-3 ye-coke isetyenziselwa ukuveliswa kwe-silicon carbide (i-abrasive material) kunye ne-calcium carbide (i-calcium carbide), kunye nezinye iimveliso zekhabhoni, ezisetyenziselwa ukwenziwa anodes for aluminiyam yokunyibilikisa iiseli Ibhloko esezantsi kwaye isetyenziselwa ukuqhushumba izitena zombane wekhabhoni okanye ukwakhiwa kwezantsi eziko.
3. Ukusetyenziswa okuphambili kwepetroleum coke
Ukusetyenziswa okuphambili kwe-petroleum coke yi-anode ebhakiweyo kwangaphambili kunye ne-anode pastes esetyenziswa kwi-aluminiyam ye-electrolytic, imveliso yekhabhoni yokuvelisa i-carbon enhancers, i-electrode yegraphite, ukunyibilikisa i-silicon yezoshishino, kunye namafutha.
Ngokwesakhiwo kunye nenkangeleko yepetroleum coke, iimveliso zepetroleum coke zinokwahlulwa zibe ziindidi ezi-4: icoke yenaliti, icoke yesiponji, iprojectile coke kunye nepowder coke: (1) Inaliti yecoke, enesakhiwo esicacileyo senaliti kunye nefiber texture, esetyenziswa ikakhulu. ukwenza intsimbi yokwenziwa kwentsimbi Amandla aphezulu egraphite electrode kunye ne-ultra-high-power graphite electrode in Ekubeni inaliti ye-coke ineemfuno ezingqongqo zesalathiso somgangatho ngokubhekiselele kumxholo wesulfure, umxholo womlotha, izinto eziguquguqukayo kunye nokuxinana kokwenyani, kukho iimfuno ezikhethekileyo zeteknoloji yokuvelisa inaliti yecoke kunye nekrwada. izixhobo.
(2) I-coke ye-sponge, ene-reactivity ephezulu yeekhemikhali kunye nomxholo ophantsi wokungcola, isetyenziswa kakhulu kwishishini lokunyibilikisa i-aluminium kunye ne-carbon industry.
(3) I-projectile coke okanye i-coke engqukuva: Imile okwengqukuva kunye ne-0.6-30mm ububanzi.Ngokuqhelekileyo iveliswa kwi-high-sulfur kunye ne-asphaltene ephezulu ye-oyile eseleyo kwaye ingasetyenziselwa kuphela njengamafutha amashishini afana nokuveliswa kwamandla kunye nesamente.
(4) I-coke ye-powder: Iveliswa yinkqubo yokucoca i-fluidized, kunye neengqungquthela ezintle (i-0.1-0.4mm ububanzi), umxholo ophezulu oguquguqukayo kunye ne-coefficient yokwandisa i-thermal, kwaye ayikwazi ukusetyenziswa ngokuthe ngqo ekulungiseleleni i-electrode kunye ne-carbon industry.
