Abstract
Emisije hlapljivih organskih spojeva u okoliš predstavljaju velik problem u zaštiti zraka, jer mogu dovesti do ugrožavanja ekosustava kao i do narušavanja zdravlja ljudi. Postoje različiti izvori njihovih emisija u okoliš. Dokazano je kako njihova prekomjerna emisija može pridonijeti nastajanju kiselih kiša, fotokemijskog smoga, učinka staklenika i drugih neželjenih pojava u okolišu. Danas postoje različite metode i tehnike kojima se može smanjiti emisija hlapljivih organskih spojeva u okoliš, a pritom se posebno izdvaja katalitička oksidacija kao jedna od najperspektivnijih metoda. U teorijskom dijelu ovog rada dan je pregled literature vezane uz odabranu temu, a posebno su analizirane metode za smanjenje emisija hlapljivih organskih spojeva u atmosferu s naglaskom na katalitičku oksidaciju. U eksperimentalnom dijelu rada prikazani su rezultati istraživanja katalitičke oksidacije toluena. Istraživanja su obuhvaćala postupak pripreme praškastog MnOx katalizatora primjenom metode precipitacije. Toluen je uobičajeni predstavnik aromatskih organskih spojeva čija povećana koncentracija u okolišu predstavlja velik problem i znanstveni izazov te se zbog toga često koristi kao modelna komponenta pri brojnim istraživanjima. Reakcija katalitičke oksidacije toluena provedena je cijevnom reaktoru s nepokretnim slojem katalizatora pri različitim radnim uvjetima. U cilju usporedbe katalitičkih značajki provedena su i dodatna mjerenja primjenom cerijevog (IV) oksida (CeO2) u praškastom obliku kao potencijalnog katalizatora.
Abstract (english)
Emissions of volatile organic compounds (VOCs) into the environment represent a major problem in air protection, because they can lead to serious endangering of ecosystem and human health. There are different sources of their emissions into environment. It has been proven that their excessive emissions can contribute to the emergence of acid rain, photochemical smog, greenhouse effect and other adverse effects in the environment. Today there are different methods and techniques that can be used to reduce VOCs emissions into the environment, and catalytic oxidation is one of the most promising methods. In the theoretical part of this work, an overview of literature related to the selected topic is given, especially methods for reducing emissions of VOCs into the atmosphere are analyzes with the emphasis on the catalytic oxidation. In the experimental part of this work the results of catalytic oxidation of toluene are presented. The powder catalyst MnOx was prepared using the precipitation method. Toluene is a common representative of aromatic organic compounds. Increased concentration of toluene in the environment is a major problem and a scientific challenge. Therefore, toluene is often used as a model component in numerous studies. Catalytic oxidation of toluene is carried out in the fixed bed tubular reactor at different operating conditions. Additional measurements are performed using cerium (IV) oxide, CeO2 in the powder form in order to compare its catalytic performance with MnOx.
