Platinum Shell Catalyst

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

The invention describes a specialized platinum- and sulfur-containing shell (or 'egg-shell') catalyst, where the active ingredients (platinum and sulfur) are concentrated in a thin outer layer of a solid support. This catalyst is used for the partial or complete dehydrogenation of fully or partially hydrogenated cyclic hydrocarbons—essentially transforming compounds used as liquid organic hydrogen carriers (LOHCs) back into their hydrogen-releasing forms. The patent also provides a method for manufacturing such catalysts.

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

• Regeneration (hydrogen release) of liquid organic hydrogen carriers (LOHCs) for hydrogen storage and transport systems.
• Production of pure hydrogen for use in fuel cells, chemical synthesis, or energy applications by dehydrogenating LOHCs on-site.
• Dehydrogenation processes in the petrochemical industry, especially involving cyclic hydrocarbons such as cyclohexane or decalin.
• Industrial chemical processes requiring efficient, selective dehydrogenation with minimal use of precious metals.

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly increased catalyst activity and efficiency, enabling high rates of dehydrogenation even at low platinum contents.
• Reduced use of expensive platinum metal while maintaining or improving catalytic performance, leading to lower operational costs.
• Shell design minimizes the required precious metal by concentrating it where it is most effective, improving metal utilization.
• High stability and selectivity in hydrogen release processes, which is crucial for LOHC and clean energy applications.
• The method is adaptable to a variety of reactor configurations (fixed-bed, fluidized-bed, etc.) and cyclic hydrocarbon substrates.
