Evonik supplies alumina and silica-alumina catalyst support materials used in chemical production, emissions-control and energy-transition catalyst systems. The support carries the active phase and determines pore structure, surface area and crush strength. The environmental performance of the finished catalyst depends on the catalyst formulation and the process it serves, not on the support material on its own. Evonik’s high-performance catalyst support materials, including AERODISP®, AEROSIL®, and SIPERNAT®, are engineered to optimize activity, stability, and longevity across a wide range of catalytic processes.
Why Choose Evonik for Catalyst and Adsorbent Support Materials?
Proven Performance: Our silicas, oxides, and binders are trusted by leading catalyst manufacturers worldwide.
Tailored Functionality: From structured carriers to dispersible binders, our portfolio supports diverse catalytic systems.
Engineered for catalyst performance: Evonik support materials are manufactured to a controlled pore structure, surface area and crush strength, which help the finished catalyst hold activity across a longer service run. Compared with a shorter-cycle support in the same reactor, a longer run means fewer catalyst changeouts over the same operating period and less spent catalyst to handle.
Solutions by Application
Catalyst Carriers & Structured Supports
Aerolyst®, VP AEROPERL®, EXP, CARPLEX® – Engineered carriers and granulates that provide optimal surface area, porosity, and mechanical strength for fixed-bed and fluid catalytic systems.
Catalyst Binders & Dispersions
AERODISP®, DYNOCEL® – High-purity dispersions and binders that ensure uniform catalyst coating, adhesion, and thermal stability in washcoat and slurry applications.
Functional Fillers & Additives
AEROSIL®, AEROXIDE®, SIPERNAT® – Fumed and precipitated silicas and oxides that enhance rheology, thermal conductivity, and active site distribution in zeolite and metal oxide catalysts.
Your Evonik Advantage
Consistent Quality: Manufactured under strict quality controls for reliable performance in demanding catalytic environments.
Global Expertise: Decades of experience in surface chemistry and catalyst formulation.
Collaborative Development: Evonik technical experts work with you to tailor support-material properties – pore volume, surface area, particle shape and mechanical strength – to your reactor and to targets you define, such as a longer catalyst cycle or lower catalyst consumption per tonne of product. Each target is measured against your current operation.
