Pars Pigment and Catalyst Co’s PARHYDCAT® Protecting :
High strength, good chemical stability, high impact resistance, large porosity, and high anti-scale ability characteristic, fills on the top of the  catalyst bed to  remove accommodate mechanical impurities in the feed oil effectively. Hydrogenation of metal removal catalyst, with high strength, large pore volume, strong carbon resistance, and scale capability removes metal ions, especially iron ions and also prevents cooking and compaction of the main hydrogenation catalyst.
Special protective catalysts for hydrogenation that can remove arsenic, organic silicon, copper, lead, and other impurity metal ions in the feed oil effectively and deposit them into their own pore channel to avoid the deactivation of the main hydrogenation catalyst by poisoning.
