CaO is the most used heterogeneous catalyst in transesterification reactions due to its high catalytic activity, low solubility in methanol, non-toxicity, and low cost. One of the greatest disadvantages of using CaO is ...

The removal of the acidity produced by the presence of volatile organic acids in bio-oils, such as acetic acid, assisted by heterogeneous catalysts was investigated. For this purpose, CaO and alumina-supported catalysts ...

Catalysts with various nickel loads were prepared on supports of ZrO2, ZrO2-Y2O3 and ZrO2-CaO, characterized by XRD and TPR and tested for activity in ethanol steam reforming. XRD of the supports identified the monoclinic ...

The petroleum crisis associated with global warming and environmental pollution has motivated researchers to investigate more profoundly the feasibility of alternative energy sources. Biofuels have been recently regaining ...

Con el fin de estudiar la reacción de transesterificación de aceite de soja empleando metanol, se prepararon catalizadores de CaO, MgO y ZnO soportados en γ-Al2O3, y mezclas en relaciones molares 0.25, 0.5, 1 y 5 entre ...

Nickel catalysts with a load of 5 wt% Ni, supported on pure ZrO(2) and ZrO(2) stabilized with 4, 8 and 14 mol% CaO, were prepared by the polymerization method. The samples were characterized by X-ray diffraction (XRD), ...
