20.500.12556/RUL-150778 Vpliv reakcijskih pogojev ter strukture Cu/Al2O3 katalizatorja na pretvorbo CO2 in H2 v CO Reaction conditions and structure of Cu/Al2O3 catalyst effect on conversion of CO2 and H2 into CO Podnebne spremembe ter globalno segrevanje v zadnjem času vedno resneje ogrožata svet. Izničiti oz. omiliti vpliv na okolje je postalo velik izziv za človeštvo. Brez konkretnih sprememb okolijske politike glede zmanjšanja koncentracije toplogrednih plinov v ozračju, bo temperatura ozračja še naprej naraščala. Globalno segrevanje povzročajo toplogredni plini. CO2 je glavni toplogredni plin v ozračju, zato je smisel iskati rešitev, kako bi zmanjšali koncentracijo ogljikovega dioksida v ozračju. Ena izmed rešitev je pretvorba CO2-ja npr. RWGS (''Reverse water gas shift'') reakcija, pri kateri z uporabo vodika pridobivamo ogljikov monoksid (CO), ki je uporaben pri sintezi metanola (CH3OH) ter raznih ogljikovodikov. V eksperimentalnem delu smo preverjali vpliv pogojev reakcije in strukture katalizatorja na njegovo aktivnost med RWGS reakcijo. Naredili smo tudi karakterizacijo katalizatorjev z različnim deležem Cu. Na koncu pa smo še preverili stabilnost katalizatorjev. Climate change and global warming have recently become more and more serious threats to the world. Eliminating or mitigating the impact on the environment has become a major challenge for humanity. Without concrete changes in environmental policy to reduce the concentration of greenhouse gases in the atmosphere, the temperature of the atmosphere will continue to rise. Global warming is caused by greenhouse gases. CO2 is the main greenhouse gas in the atmosphere, so it makes sense to look for a solution to reduce the concentration of carbon dioxide in the atmosphere. One solution is the conversion of CO2, e.g. the RWGS (''Reverse water gas shift'') reaction, which uses hydrogen to produce carbon monoxide (CO), which is useful in the synthesis of methanol (CH3OH) and various hydrocarbons. In the experimental part, the influence of the reaction conditions and the structure of the catalyst on its activity during the RWGS reaction was investigated. Characterisation of the catalysts with different Cu was also carried out. Finally, the stability of the catalysts was checked.
