Lub luag haujlwm ntawm Petroleum Coke

Petroleum coke yog cov khoom sib cais lub teeb thiab hnyav roj los ntawm distillation, thiab tom qab ntawd hloov cov roj hnyav los ntawm cov txheej txheem thermal tawg. Petroleum coke yog cov khoom siv roj av dub lossis grey tawv tawv nrog cov xim hlau luster thiab porosity. Nws yog tsim los ntawm granular, columnar los yog acicular carbon tsim los ntawm me me graphite crystals.
Petroleum coke muaj hydrocarbons uas muaj 90 mus rau 97 feem pua ​​carbon, 1.5 mus rau 8 feem pua ​​hydrogen, thiab nitrogen, chlorine, sulfur, thiab hnyav hlau compounds. Nws cov ntsiab lus tseem ceeb yog carbon, suav txog ntau dua 80%, cov duab tsis zoo, qhov sib txawv, thiab cov qauv ntxeem tau.
Raws li qhov zoo thiab kev siv roj av coke, nws tuaj yeem siv rau hauv kev tsim cov graphite electrodes thiab anodic arc, nrog rau cov hlau, cov hlau tsis muaj hlau thiab txhuas smelting kev lag luam. Ntawm lawv, tsis tshua muaj leej faj thiab zoo coke siav yog tsuas yog siv los ua ultra-siab zog graphite electrode thiab qee cov khoom tshwj xeeb carbon. Nruab nrab leej faj thiab cov coke siav yog siv dav hauv aluminium smelting. High-sulfur, zoo tib yam cokes ntsuab yog siv nyob rau hauv tshuaj ntau lawm, xws li calcium carbide thiab silicon carbide, thiab raws li fuels rau hlau casting.
Tsis tas li ntawd, thaum cov roj av coke siv los ua roj, nws yuav tsum tau mus los ntawm cov txheej txheem thev naus laus zis, xws li crushing thiab sib tsoo, ziab pretreatment, tov khoom, raw khoom preheating, coking tshuaj tiv thaiv, tar sib cais, coke sib cais, coke kho thiab furnace gas kev kho mob, kom tau raws li qhov yuav tsum tau ntawm kev lag luam sib txawv thiab siv.
Feem ntau, roj av coke yog ib qho tseem ceeb ntawm cov khoom siv raw thiab muaj ntau yam kev siv hauv ntau qhov chaw. Yog xav paub ntxiv txog roj av coke, nws raug nquahu kom sab laj cov ntaub ntawv los yog sab laj nrog kws kho mob.
