Catalyst performance is paramount in producing high value lubricants. Refiners trust our catalysts to deliver high yields of top-quality base oils. Consequently, our products are to be found in lubricant plants across the world, including the world’s largest GTL plant – Shell Pearl in Qatar.

Lubricant base oils are manufactured from vacuum gas oils and high-quality deasphalted oils. These feedstocks are improved through several processing steps, including “lube hydrocracking” dewaxing/isomerisation, hydrofinishing and hydrotreating.

Criterion has a proven record of delivering high yields and enhanced quality lubricant base oils through its range of high‑performance catalysts for use in these key processes.

Arsenic Protection

*Improved*

NiMo - Naphtha Hydrotreating Trilobe catalyst on a high surface area alumina extrudate specially formulated to trap Arsenic (As) present in a wide range of petroleum feedstocks. Protects high activity catalysts for significantly longer periods from arsenic poisoning. Demonstrates exceptional stability in this severe environment.
DN-3552*New* Lube hydrotreating This widely used NiMo catalyst utilizes Criterion’s Ascent technology and is used for mild hydrofinishing and hydrotreating, including the manufacture of food grade waxes.
LH-21 Lube oil Hydrocracking Criterion LH-21 is specifically intended to be used in lube oil processing units, both for the purpose of increasing VI through hydrocracking of deasphated oils and vacuum gas oils and for the purpose of producing highly saturated products with a minimum of conversion.
LH-22 Lube oil Hydrocracking Criterion LH-22 is a higher activity conversion catalyst designed for use in Lube oil processing units. Intended feedstocks include vacuum gas oils and deasphalted oils.
LH-24 Lube Hydrocracking Pretreat A high activity pretreat catalyst based on Criterion’s CENTINEL GOLD technology. Applied alone for base oil hydrotreating or combined with LH-21 or LH-22 for the production of high VI base oils, specifically in applications requiring increased desulfurization.
LH-26 Lube Hydrocracking Pretreat A highest activity and stability pretreat catalyst based on Criterion’s CENTERA(R) technology. Applied alone for base oil hydrotreating or combined with LH-21 or LH-22 for the production of high VI base oils, specifically in applications requiring increased desulfurization.
LH-27 Lube oil Hydrocracking This lubes-optimised cracking catalyst is specifically intended to be used in lube oil processing units either alone or in a stack, to increase VI through hydrocracking of deasphalted oils and vacuum gas oils. LH-27 will produce highly saturated products with additional yield retention while boosting VI into the Group 2+ and Group 3 range.
654 Lube oil finishing Designed for essentially complete saturation of aromatic compounds, and is intended for the production of food grade and technical grade white oils.
684 Lube oil finishing Criterion 684 is the newest noble metal saturation catalyst, offering all the advantages of the long-proven and successful 654 and with improved activity and stability in the presence of increased levels of sulfur and H2S.
688 Lube oil Finishing This noble metal saturation catalyst is the highest activity saturation catalyst, offering all the advantages of C-684 with higher metals content for further enhanced saturation performance in the presence of increased levels of sulphur and H2S.
SLD-821 Lube oil Dewax High-activity lubes dewaxing catalyst for both naphthenic units and paraffinic units primarily targeting Group 2 and Group 2+ base oils products. SLD-821 offers the highest activity and stability leading to an extended cycle life.
SLD-861 Lube oil Dewax This lubes dewaxing catalyst offers very high yield retention with enhanced selectivity to more valuable heavy products. Coupled with high VI retention, SLD-861 is ideally suited to units targeting heavy Group 2+ or Group 3 products and/or requiring large shifts in cold flow properties.
SLD-800 Lube oil Dewax This base metals dewaxing catalyst has been optimised for lubes performance. It provides a high yield retention with excellent stability in the presence of high levels of H2S and NH3.
