Catalyst Material for the Dehydrogenation and/or Hydrogenation of Hydrogen Carrier Material and Method for Producing Such a Catalyst Material

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a new type of catalyst material designed specifically for the dehydrogenation and/or hydrogenation of hydrogen carrier materials, such as liquid organic hydrogen carriers (LOHCs). The catalyst features a carrier material with a modified surface that significantly reduces its surface energy, allowing for improved reaction efficiency and less catalyst deactivation. The active catalytic material (such as platinum or palladium) is supported on this surface, and the surface modifications (using e.g., fluorosilanes or graphite layers) facilitate the formation of hydrogen gas bubbles at lower temperatures, which improves the overall hydrogen release/re-absorption process.

Use CasesContent extracted from patent full text and abstract with AI.

• Hydrogen storage and release systems using LOHCs for renewable energy applications.
• Hydrogen fueling stations where efficient hydrogen release from carriers is necessary.
• Decentralized or mobile hydrogen generation units for industrial or transportation sectors.
• Production or recycling facilities for LOHC-based hydrogen technologies.
• Chemical process industries requiring efficient catalytic hydrogenation/dehydrogenation reactions.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced catalyst activity and stability over multiple cycles with less deactivation.
• Lower operating temperatures for hydrogen release, improving energy efficiency and safety.
• No need for frequent reactivation or mechanical intervention, reducing maintenance.
• Supports better volumetric and gravimetric power densities in hydrogen storage/release.
• Flexible manufacturing methods for various catalyst/carrier combinations, including ceramics, activated carbon, and monoliths.
• Potential reduction in operational costs and improved process reliability for hydrogen technologies.
