Abstract
This thesis presents a study on the production of hydrogen through ethanol steam reforming. The objective of this study was to investigate the kinetics of the ethanol steam reforming reaction. The primary focus was to identify the most suitable catalyst for this reaction based on its kinetic properties. Two different catalyst compositions, namely a cobalt-nickel alloy with a ratio of 35% cobalt and 5% nickel (referred to as 35Co05Ni catalyst) and a cobalt-nickel alloy with equal proportions of 20% cobalt and 20% nickel (referred to as 20Co20Ni catalyst), were employed for the experiments. The obtained results indicated that the utilization of the 20Co20Ni catalyst resulted in a determined reaction order of 0.92 for ethanol, while the 35Co05Ni catalyst exhibited a reaction order of 1.06.
The reaction order signifies the relationship between the concentration of the reactants and the rate of the reaction
