Ibikoresho nyamukuru bya kokiya ibarwa ni kokiya ya peteroli, kandi kokiya nziza yo mu rwego rwo hejuru ikorwa na kokiya ya peteroli ibarwa ku bushyuhe bwinshi.

Nyuma yo kubara kuri 1250 ℃, ubuhehere no guhindagurika kwa kokiya ya peteroli bivanwaho, bityo bikongera karubone yibikomoka kuri peteroli, bikagabanya ubukana bwa kokiya ya peteroli kandi bikarushaho kuba byiza.Byongeye kandi, nyuma yuburyo 12, micro-pores muri buri karubone ya karubone iravurwa, kugirango indangagaciro za "super pass, gushonga byihuse no kwinjiza" murwego rwo gukoresha zitezimbere cyane.

Ibikoresho fatizo bya kokiya yujuje ubuziranenge ni kokiya ya peteroli, ariko biroroshye cyane kubitandukanya.Uhereye hejuru, icyuma kibisi cya kokiya kibarwa kirakomeye, kandi imyuka ya karubone iragaragara cyane nyuma yo kubara.Ubucucike bwa kokiya ya peteroli ni hejuru cyane kandi iremereye kuruta iyo kokiya yabazwe.Igice kinini cyibikomoka kuri peteroli ni karubone, naho ibindi ni amazi, ivu, sulfure nandi mwanda, hamwe na kokiya yabazwe nyuma ya kokiya ya peteroli ibarwa kugirango ikureho ivu ryinshi ryamazi nandi myanda yanduye, ni ukuvuga, birenze bihagije ibikoresho bibisi bibarwa, nibyiza nibice bigize ibice bya kokiya yabazwe, nibyiza kubiranga ibicuruzwa.

Muri make, ibikoresho fatizo bya kokiya yo mu rwego rwo hejuru ibarwa ni kokiya ya peteroli, kandi uburyo bwo kubara ubushyuhe bwagenzuwe bwa Jia-karubone icyenda-icyegeranyo cya tanki yo kubara itanura rishobora kwemeza ubuziranenge bwa kokiya ya peteroli kandi ikabyara kokiya nziza ibarwa nyuma yamasaha 48 yo kugenzura ubushyuhe bugenzurwa.
