The performance of two copper-based catalysts, Cu/ZrO2 and Ga2O3/Cu/ZrO2, in regards the reverse water gas shift (RWGS) reaction as compared with their reaction rates for the methanol synthesis reaction (RCH3OH) was studied ...

Cu-ZnO-Al2O3 catalysts for the low-temperature water-gas shift reaction were prepared using methods of direct and reverse coprecipitation. The catalysts obtained were characterized by DRX, TPR, XPS, N2O chemisorption, ...

Concentration-modulation excitation spectroscopy (MES) experiments in combination with phase-sensitive detection (PSD) were used to monitor the gas–solid interface by means of in operando diffuse reflectance infrared ...

Catalysts containing NiO/MgO/ZrO(2) mixtures were synthesized by the polymerization method in a single step. They were characterized by X-ray diffraction (XRD), temperature programmed reduction (TPR) and physisorption of ...

Biomass gasification technology is of constant interest in the field of sustainable energy, being used as an alternative to traditional combustion technology, especially due to the reduction in the emission of dust and ...

Two series of supported palladium catalysts (2 wt%) were prepared on ZnO–CeO2nanocomposites (Zn-to-Ce atomic ratio between 0.5 and 2) obtained by oxalate or carbonate coprecipitation (OC and CC series,respectively). Methanol ...

The hydrogenation process of Natural Gas (NG) with high CO2 content can potentially be employed for a novel process of methanol production that avoids CO2 extraction and emission, at the same time yielding high CO2 conversion ...

With the increasing environmental appeal nowadays, the question arises: how to use carbon dioxide in a way that reduces its impact on the environment? One possibility is the capture of CO2 and its transformation into ...

Neste trabalho, foram obtidos catalisadores de ouro suportado em materiais mesoporosos do tipo MCM-41 e Al-MCM-41, destinados à reação de deslocamento de monóxido de carbono com vapor d´água, uma importante etapa na geração ...
