Abstract
Magnesium hydride is well known as the ideal candidate for solid-state hydrogen storage and thermochemical thermal storage since both gravimetric and volumetric storage are considerably high. The main drawbacks of magnesium hydride are thermodynamic unfavorable and poor kinetic. Adding Nickel as a catalyst, which mainly incorporates mechanical modification (alloying or particle size reduction), can accelerate the reaction rate and decrease the enthalpy formation. It is hard to determine the catalytic of Nickel in magnesium hydride for the kinetic rate improvement. This study is focused on the observation of the effect of Nickel on magnesium hydride by using the market size availability of magnesium and nickel powder (74 μm for Mg and 63 μm for Ni). Mg and Ni are mixed by Ni variation (weight %) from 14%, 15%, and 16%. The characterization starts with initial hydrogenation and dehydrogenation, continues with activation and PCI measurement to obtain the kinetic characteristic of each sample. From this study, it is clear that the increase in nickel ratio will improve the rate of reaction for magnesium hydride, where the maximum storage for magnesium hydride is 4.2% by adding 16 wt% nickel.
期刊介绍:
WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
