Možnosti snovne in energijske izrabe katodnega odpada iz elektroliznih celic pri pridobivanju aluminija : magistrsko deloMikša, DraganS poveèanjem svetovne proizvodnje aluminija naršèa tudi dele odpadkov, povezanih z aluminijsko industrijo. Izrabljene obloge elektroliznih celic predstavljajo najveèji okoljevarstveni problem v ... aluminijski industriji. Katodni odpad je sestavljen iz: 55 odstotkov ogljikovih materialov in 45 odstotkov opeke. Na re evanje nastalega odpadka vplivajo trije dejavniki: 1. izrabljene obloge elektroliznih celic so klasificirane kot nevarni odpadek, 2.poveèevanje odlagali ènih taks, 3. onemogoèenost odlaganja odpadkov na deponije. Po laboratorijskih preiskavah smo prišli do zakljuèka, da predstavljajo glavni problem pravzaprav topni fluoridi in cianidi. Z laboratorijskimi raziskavami smo raziskali obnašanje fluoridov in cianidov pri povišanih temperaturah. Na osnovi laboratorijskih raziskav smo se usmerili predvsem na možnost ponovne uporabe izrabljenih oblog elektroliznih celic v opekarnah, cementarnah in termoelektrarnah. Opeène obloge elektroliznih celic snovno ponovno uporabljajo v opekarni. Ogljikove obloge elektroliznih celic smo hoteli s poizkusom energijsko izrabiti v cementarni. Izdelali smo napoved emisijskih vrednosti fluoridov pri sosežigu ogljikovih oblog v termoelektrarni. V vseh treh primerih ponovne uporabe katodnega odpada nismo zaznali poveèanega vpliva na okolje. Cianidi so v procesu termiène obdelave absorbirani ali unièeni.Type of material - master's thesisPublication and manufacture - Maribor : [D. Mikša], 2004Language - slovenianCOBISS.SI-ID - 8587542
