Product Detail

The long service life and optimum performance translate into lower operating costs.

Maximum resistance to erosion and attrition minimizes the possibility of catalyst contamination.

Extraordinary ability to withstand extreme thermal shock without breaking.

High crush strength permits using deep beds.

Better impact resistance.

Withstands rapid depressurization.

Be free of sulfur, boron and other common catalytic poisons.
