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 invention describes a novel catalyst material designed for improved dehydrogenation and/or hydrogenation of hydrogen carrier materials, particularly for liquid organic hydrogen carriers (LOHCs). The catalyst consists of a carrier support with a reduced surface energy achieved by surface modification, on which catalytically active metals (such as platinum, palladium, nickel, rhodium, or ruthenium) are immobilized. This specific surface modification minimizes loss of catalyst activity over time, supports efficient gas bubble nucleation for hydrogen release, and allows the process to operate at lower temperatures without requiring mechanical or thermal reactivation of the catalyst.

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

• Hydrogen storage and release systems, especially for renewable energy applications
• Efficient hydrogen supply for fuel cells in transportation, stationary, or portable applications
• Industrial hydrogenation or dehydrogenation processes utilizing LOHC (liquid organic hydrogen carrier) technology
• Hydrogen infrastructure systems for refueling stations or grid stabilization
• Improvement and longevity of catalyst beds in reactors for hydrogen generation or storage

BenefitsContent extracted from patent full text and abstract with AI.

• Increased durability and lifetime of the catalyst due to reduced deactivation and no need for frequent reactivation measures
• Enhanced efficiency and performance of hydrogen release, enabling lower operating temperatures and energy savings
• Sustained catalyst activity during repeated cycling, leading to more reliable operation
• Simplified system design and maintenance due to elimination of mechanical reactivation steps
• Potential for significant cost reduction in hydrogen storage and release processes through improved material design
