Catalyst System

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

This invention presents a method for producing advanced catalyst systems in which spherical activated carbon acts as a carrier. The carbon is first oxidized to improve its surface properties, then a catalytically active metal component (such as platinum, palladium, or ruthenium) is applied. The resulting catalyst may also undergo a reduction step for activation. This approach yields highly active, stable, and mechanically robust catalysts that overcome many disadvantages of conventional powdered activated carbon catalysts, such as poor recovery, low mechanical stability, and inefficient catalyst loading.

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

• Industrial chemical catalysis, including hydrogenation, oligomerization, and polymerization reactions, especially in both continuous and batch processes.
• Environmental applications for the removal of pollutants, odors, and toxic substances from air and gas streams (e.g., air purification, filters in protective masks).
• Use as a catalyst or catalyst carrier in refining and fine chemicals manufacturing.
• Incorporation in filters for medical, civil, or military protective gear (e.g., CBRN suits, gloves, masks).
• Gas sensors for industrial or environmental monitoring.
• As components in fuel cells (electrochemical applications).
• Gas or liquid sorption/storage systems, particularly where reactive or catalytic adsorption is required.
• Cleanroom atmosphere control, particularly in the electronics or semiconductor industry.

BenefitsContent extracted from patent full text and abstract with AI.

• Enhanced catalyst stability and reusability due to mechanical strength and reduced attrition of the spherical carrier.
• Significantly improved loading and retention of catalytic metals thanks to the pre-oxidized, functionalized surface, leading to longer catalyst life and higher activity.
• Homogeneous distribution of the catalyst throughout the carbon sphere, avoiding surface-only loading and improving reaction efficiency.
• Lower pressure drop and higher flow rates in continuous reactors or filters due to optimized particle shape and size, preventing clogs and reducing operational downtime.
• Reduced loss of catalyst material during filtration or separation, making processes more economical and environmentally friendly.
• Tailorable performance through control of particle size, porosity, and metal loading for specific applications or process needs.
• Improved separation and recycling of the catalyst in industrial processes, saving costs and materials.
• Superior performance compared to traditional powder-based or irregularly-shaped activated carbon catalysts, particularly in process speed and product yield.

Patent Abstract

The invention relates to a method for producing a catalyst system having at least one catalytically active component, wherein the catalytically active component comprises at least one metal, wherein first a spherical activated carbon used as a catalyst carrier is subjected to an oxidation. Subsequently, the catalytically active component is applied, optionally followed by a reduction of the catalyst system obtained in said manner.
