High-Performance Alumina Catalyst Carriers: Raschig Rings & Microspheres
Engineered for reliability in demanding catalytic processes, our alumina catalyst carriers (CAS 21645-51-2) are available in Raschig Ring and Microsphere forms. They provide the ideal combination of high surface area, superior mechanical strength, and thermal stability to maximize catalyst efficiency and lifespan in petroleum refining, chemical synthesis, and environmental applications.
Product Overview & Key Advantages
Our carriers are manufactured from high-purity aluminum hydroxide, ensuring consistent performance. Key benefits include:
Optimized Pore Structure: Available in macroporous, mesoporous, and microporous configurations to suit specific reaction kinetics.
Exceptional Mechanical Strength: High crush strength and low attrition minimize breakdown and active component loss, reducing reactor pressure drop and operational costs.
High Thermal Stability: Maintain structural integrity under high temperatures and during thermal cycling.
High-Purity & Customization: Low impurity content (Fe₂O₃, SiO₂, Na₂O) prevents catalyst poisoning. We offer custom shapes (spherical, cylindrical, clover, hollow) and physical specifications.
