No full textCO2 transformation to MeOH using high entropic oxide catalysts
No full textTo address stability issues caused by sintering of Cu based catalysts for methanol synthesis, a high entropy concept was applied to develop improved catalysts for CO2 hydrogenation. By applying at least five different materials in a single phase, an entropy driven stabilisation is achieved in a high entropic oxide. Initially, screening experiments of material combinations consisting of Pd and Cu on oxide supports comprising variations of Al, Ce, In, Nb, Zn, and Zr were performed. A strong dependence of the methanol yield on the material combinations was determined. From these experiments, the combination of PdCu2/AlCeZnZrOx was determined to have the best performance. Further optimisation of this catalyst revealed that increasing the Cu content and removing Pd significantly enhances the catalyst performance. With a higher Cu content, characterisation of the catalysts revealed that Cu agglomerates on the surface leading to a decrease in stability. Variation of the molar composition and activation of the catalyst before the reaction were identified as two possibilities to counteract sintering of Cu and increase the catalyst stability. Experiments with different promoter materials revealed that the addition of small amounts of Ca to the catalyst leads to an increase in performance by about 10 %.Author Florian Kühberger, BScMasterarbeit Johannes Kepler Universität Linz 202
Evaluation of Effects of "Cash for Clunkers"-like programs on car markets and macroeconomic situation
No full textBachelor's Thesis Proposal Institute of Economic Studies Faculty of Social Sciences Charles University in Prague Author Florian Fiebig Supervisor Mgr. Ing. Vilém Semerák PhD. Proposed topic: The Impact of German policy, cash for clunkers, on the Czech market in regards to price level and output. Topic characteristics After the financial crisis in 2007-08, governments all over the world tried using several policies in order to promote growth and stability for their economies. On July 1, 2009, the USA launched its policy "Car Allowance Rebate System (CARS)", commonly known as "Cash for clunkers." It was a program designed to boost car sales, by giving the US residents an economic incentive swap their old and economic inefficient cars for brand new models that are more fuel efficient as well as produce less CO2. In the same year, Germany tried to promote growth and stability using the same policy/program. However, this policy did not just had an impact on the German economy, but its neighbors as well. In addition to that, it is interesting to find out if this policy was beneficial to implement or rather harming the economy even further. Although several papers conducted research on the effects of the cash-for-clunkers policy, I will focus on the effects that the German policy had on the Czech economy with..
CO2-Hydrierung zu Methanol an geförderten In2O3-Katalysatoren
No full textHerein methanol (MeOH) was snythezised from a CO2/H2 gas mixture using a Pd/In2O3 catalyst. The catalyst in question was prepared by synthesising an indium metal organic framework (MOF). The indium MOF was snythezised using 1,1,3,3-tetramethylguanidine (TMG) for deprotonation of the organic linker and dimethylformamide (DMF) as a solvent. Different solvents were tested to replace DMF, but ultimately failed. The MOF synthesis was also carried out at different temperatures. The highest yield was obtained at 100°C with DMF. The MOF synthesis helps to ensure a uniform Pd distribution, as clusters of Pd would reduce the efficiency of MeOH production and increase the reverse water gas shift reaction. The resulting MOF was impregnated with different concentrations of Pd(NO3)2 solutions. The impregnated MOF was then calcined at different temperatures to obtain the desired In2O3 catalyst with different Pd contents. These catalysts were mixed with TiO2 and then used for the synthesis of MeOH in a fixed bed reactor. The reactor conditions were 50 bar, 280°C and the gas flow was set at 160 NmL/min. The results of all the catalysts measured were used to construct a volcano plot and determine the best catalyst. The best catalyst performance was the 1.25 wt% Pd loaded In2O3 catalyst with a space time yield (STY) of 633.0 mgMeOH h-1 gcat-1.Author Florian SmrzkaAbweichender Titel laut Übersetzung der Verfasserin/des VerfassersMasterarbeit Universität Linz 202
