This book was released on 2014-12-23 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methanol is one of the most important industrial base chemicals and also a starting material for many organic syntheses. A steadily rising amount is used as fuel or fuel additive because methanol can serve as liquid hydrogen carrier. In the chemical industry, methanol is produced from synthesis gas over Cu/ZnO based catalysts. The catalyst is prepared by a multi-step synthesis (co-precipitation, calcination, reduction). Already in early stages of the preparation structural characteristics can provide indications for the resulting activity of the final catalyst. In order to investigate correlations between preparation parameters, microstructure and activity of Cu/ZnO based catalysts, the effects of the pH during co-precipitation and aging, use of MgO instead of ZnO and doping with Ga-ions were examined in the present work. Precursors, calcined and reduced samples were investigated with different methods (XRD, XRF, physisorption, TPR, RFC, UV-Vis spectroscopy, XAS, XPS, SEM, TEM) and selected samples were tested in methanol synthesis.

Download or read book Chemical Energy Storage written by Robert Schlögl and published by Walter de Gruyter GmbH & Co KG. This book was released on 2022-01-19 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy – in the headlines, discussed controversially, vital. The use of regenerative energy in many primary forms leads to the necessity to store grid dimensions for maintaining continuous supply and enabling the replacement of fossil fuel systems. Chemical energy storage is one of the possibilities besides mechano-thermal and biological systems. This work starts with the more general aspects of chemical energy storage in the context of the geosphere and evolves to dealing with aspects of electrochemistry, catalysis, synthesis of catalysts, functional analysis of catalytic processes and with the interface between electrochemistry and heterogeneous catalysis. Top-notch experts provide a sound, practical, hands-on insight into the present status of energy conversion aimed primarily at the young emerging research front.

This book was released on 2006 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several methods (sol-gel method, co-precipitation, homogeneous-precipitation) have been comparatively examined for the preparation of binary Cu/ZnO-based catalysts with Cu/Zn molar ratios in 70/30, 50/50 and 30/70 copper acetate (Cu(CH3COO)2H2O) and zinc acetate (Zn(CH3COO)2 2H2O) and ethanol were used as precursor for preparation of Cu/ZnO catalyst by sol-gel method. For co-precipitation method were prepared by the addition rate of a mixed copper nitrate (Cu(NO3)2) and zince nitrate (Zn(NO3)2) solution with a sodium carbonate (Na2CO3) solution. For homogeneous precipitation method were prepared by urea instead of Na2CO3 solution. All Cu/ZnO catalysts were applied for the catalytic production of hydrogen by steam reforming of methanol (SRM). Homogeneous precipitation method is preferable for this reaction. Then, study effect of calcinations conditions. Cu/ZnO catalysts are calcined by various atmospheres. Gases were used as atmosphere as follows: nitrogen, oxygen, air and hydrogen. Cu/ZnO catalyst was calcined by hydrogen, is the higher activity than the other atmospheres. Physical and chemical properties of Cu/ZnO catalyst were characterized by various techniques including X-ray diffraction (XRD), BET surface area, N2O chemisorption, Thermal gravimetric and differential thermal analysis (TG/DTA), Transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR).

Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
