| Sumario: | Renewable energies are the key for energy production in the near future. Among them, hydrogen technologies are expected to be used in a wide range of applications. The aim of this project is the study of a set of catalysts made of nickel, platinum and different supports such as ceria and magnesium/aluminum oxides, for the catalytic production of hydrogen. The catalysts studied were produced under different conditions, combining the compounds with different ratios and then tested separately during a reaction process. This process is the widely studied Steam Methane Reforming (SMR) reaction, which is the main method used for the catalytic production of hydrogen in the world, even though several advances can still be made with the purpose of improving the catalysts used and the process itself. Then, each reaction test was analyzed in order to obtain the conversion, selectivity and yield produced by each catalyst, with the goal of selecting the best one for the SMR process. Some of the samples obtained post-reaction were also studied using different techniques such as X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy for a characterization of the catalysts after reaction. |
