Residential stoves, commonly used for heating, are a significant source of emissions due to the harmful substances produced during biomass combustion, yet they remain largely unregulated. The use catalytic systems presents promising approach mitigating these emissions. This study investigates potential Cu‐Mg‐Mn‐Al and Co‐Mg‐Mn‐Al mixed metal oxides, synthesized from hydrotalcite precursors via coprecipitation calcination, reducing CO, C₃H₈, CH₄. physicochemical properties catalysts were...
Abstract Industrial hydrogenolysis of esters to alcohols relies on the use Adkins catalysts whose production and disposal is an environmental burden. This work focused CuZn that represent ecological alternative catalysts. Four with Cu/Zn atomic ratio ranging from 0.5 2.0 single phase CuO ZnO were prepared by co‐precipitation their activity was compared a commercial catalyst. Dimethyl adipate used test catalyst performance in flow reactor at temperatures 175 205 °C hydrogen pressure 16 MPa....
SrTiO3-based powder materials with the general formula: SrTi0.98Me0.02O3, Sr0.95Ti0.98Me0.02O3 and Sr0.9Ti0.9Me0.1O3 where Me = Cu, Co were synthesised by modified sol-gel method followed proper thermal treatment. For all materials, particle size distribution had a bimodal character. The Energy Dispersive Spectroscopy (EDS) results showed that cobalt was regularly homogeneously distributed in while for Cu-modified samples areas enriched copper observed. phase analysis implied strontium...
Cu-Al-O x mixed metal oxides with intended molar ratios of Cu/Al = 85/15, 78/22, 75/25, 60/30, were prepared by thermal decomposition precursors at 600 °C and tested for the nitrous oxide (deN2O). Techniques such as XRD, ICP-MS, N2 physisorption, O2-TPD, H2-TPR, in situ FT-IR XAFS used to characterize obtained materials. Physico-chemical characterization revealed formation characterized different specific surface area thus, oxygen default sites. The O2-TPD results gained conform closely...
Fundamental research on direct NO decomposition is still needed for the design of a sufficiently active, stable and selective catalyst. Co-based mixed oxides promoted by alkali metals are promising catalysts decomposition, but which parameters play key role in over oxide catalysts? How do applied preparation conditions affect obtained catalyst’s properties? Co4MnAlOx potassium calcined at various were tested with aim to determine their activity, stability selectivity. The prepared...
Multicomponent oxide systems 800-Cu-Mg-Fe-O and 800-Cu-Mg-Fe-O-Ce were tested as catalysts of selective catalytic oxidation ammonia to dinitrogen (NH3-SCO) process. Materials obtained by calcination hydrotalcite-like compounds at temperature 800 °C. Some doped with cerium the wet impregnation method. Not only simple oxides, but also complex spinel-like phases formed during calcination. The influence chemical composition, especially occurrence spinel phases, copper loading cerium,...
The K-doped Co–Mn–Al mixed oxide deN2O catalyst was prepared by calcination of layered double hydroxide, subsequent impregnation with KNO3, and shaping into tablets 5 mm × mm. Tablets were tested for N2O decomposition in pilot scale reactor connected at the bypassed tail gas from nitric production plant downstream SCR NOx/NH3 aim to perform kinetic measurements. Special attention paid study changes catalytic performance, which monitored using both long-term test comparison physical–chemical...
Abstract Co 3 O 4 oxide catalysts prepared on different commercial supports, namely, TiO 2 , Al and Mg‐Al mixed oxides with various Mg concentrations, were characterized by atomic absorption spectrometry, Brunauer‐Emmett‐Teller method, X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, H temperature‐programmed reduction, tested for N decomposition, compared bulk . In spite of the fact that /70Mg30Al also contained hardly reducible compounds, it...
