Inert ceramic balls DURANIT®, 2, VFF
Overview

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.
