Description

DURANIT®- ideal compressive strength for maximum operational reliability. Processes in which catalyst calipers are used in accordance with international specifications cover a whole range of thermal and catalytic transformations of the substance: Duranit® inert balls and other forms can also be used for other purposes, for example, in high-temperature filtration to separate solid and liquid particles from hot exhaust gases. Applications: alkylation, catalytic reforming, dehydrogenation, hydrotreating, desulfurization, isomerization, catalytic cracking, power forming, catalytic conversion, thermal cracking, catalytic oxidation and other processes. Chemical composition: SiO2 ≤ 80% Al2O3 ≥ 20% TiO2 < 2% Fe2O3 < 1,5% CaO + MgO ≤ 1% K2O + Na2O ≤ 4% Characteristics: Specific surface area according to the BET method <0.1 m2 / g Mohs hardness ~ 8 Specific heat: ~ 0.8 kJ•(kg * K) Thermal conductivity: ~6 kJ / (M * h * K) Thermal expansion: ~5•10-6 1/ K Maximum temperature: ~1000°C Water absorption (DIN EN 993-1): < 3%
