NSR-119
a proprietary, nickel based catalyst used for protection of main bed hydrotreating catalyst from arsine poisoning. The product is sensitive to trace and elevated levels of arsine and can remove about > 6 wt% of arsine impurities at optimum conditions.

NSR-120
a proprietary, NiMo based catalyst used for protection of main bed hydrotreating catalyst from Si poisoning. The product is sensitive to trace and elevated levels of Si and can remove about > 14 – 24 wt% of Si metal impurities at optimum conditions.

NSR-121
a proprietary, NiMo based catalyst used for protection of main bed hydrotreating catalyst from silica poisoning. The product is sensitive to trace and elevated levels of Si and can remove about > 20 – 28 wt% of Si metal impurities at optimum conditions.

MR1P
a proprietary, NiMo based catalyst with ultra-high pore volume to trap and remove ppm levels of metals; nickel, lead or vanadium; from a full range of hydrocarbon feed stocks in modern day hydrotreater reactors. MR-1P is for use in the top layers HDT, HDS and HDN units or in lead position, metal removal, and guard bed unit.

NSR-131
a proprietary, inert based catalyst used for protection of main bed hydrotreating or other fixed bed catalyst systems from silica poisoning. The product is sensitive to trace and elevated levels of Si and can remove about > 20 wt% of Si metal impurities at optimum conditions.
