Catalyst System and Method for Catalytic Dehydrogenation of a Hydrogen Carrier Material, Reactor Arrangement with Such a Catalyst System, and Method for Producing Such a Catalyst System

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

This patent describes a catalyst system and method for efficiently releasing hydrogen from liquid organic hydrogen carriers (LOHCs) by catalytic dehydrogenation. The invention specifically uses a combination of platinum, rhenium, and sulfur as active materials on a suitable carrier material (such as alumina), which can be tailored in layered zones within a reactor or across multiple reactors. This composition improves both the activity (speed) and selectivity (reduced side-products) of the dehydrogenation process, enabling more efficient and cleaner hydrogen extraction from organic carrier fluids.

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

• Hydrogen fueling stations for vehicles using LOHC technology
• Industrial hydrogen supply from LOHC-based storage systems
• Hydrogen backup or grid stabilization systems that require on-demand hydrogen release
• Portable or remote hydrogen generation from liquid storage media
• Integration with renewable energy storage and conversion systems relying on chemical hydrogen carriers

BenefitsContent extracted from patent full text and abstract with AI.

• Increased hydrogen release rates due to improved catalytic activity (especially enabled by rhenium).
• Lower production of undesired by-products, thanks to improved selectivity (especially enabled by sulfur).
• Enables use of LOHCs for safe, compact, and reversible hydrogen storage, facilitating hydrogen economy infrastructure.
• Flexible reactor and catalyst design to optimize performance based on hydrogen loading of the carrier fluid.
• Catalyst composition and layering can be tailored for specific process conditions, improving operational efficiency and longevity.
• Simplified reactor designs and possible reduction in purification steps thanks to improved selectivity.
