Nickel and vanadium removal

Capture and store contaminants

Nickel and vanadium are often found in heavier hydrocarbon fractions such as vacuum gas oil (VGO), to a lesser extent in heavy coker gas oil, but particularly in deasphalted oil (DAO).

When nickel and vanadium deposit on the catalyst, they deactivate the catalyst by plugging up the pore system. In general, the higher a feedstock’s distillation end-point, the higher the concentration of nickel and vanadium. This explains why the problem occurs frequently in fluid catalytic cracking (FCC) pretreaters running on heavy feedstocks.

We offer a very comprehensive portfolio of guard catalysts that effectively trap nickel and vanadium before they reach your high-activity main catalyst. Our guards deliver very high hydrodemetallization (HDM) activity and capacity, ensuring that they not only capture contaminants, but can store them throughout the cycle length.

Catalysts for nickel and vanadium removal

TK-453 SiliconTrap™ catalyst

A NiMo catalyst with very high rates for removal of metals (Ni, V, Fe) and silicon. This is an excellent guard in hydrotreaters that process heavy feeds.

TK-455 MultiTrap™ catalyst

A high-porosity catalyst for trapping silicon and phosphorus in VGO feeds. The unique pore system enables it to also pick up metals (Ni, V and Fe) and provide high capacity for metal storage.

TK-709 catalyst

A high-surface area, low-activity catalyst with high hydrodemetallization (HDM) activity and metal storage capacity. This catalyst is typically used in various grading applications for all types ...

TK-711 catalyst

A catalyst with high hydrodemetallization (HDM) activity, metal storage capacity and moderate hydrodesulfurization (HDS) activity.

TK-719 catalyst

A high-porosity demetallization catalyst for fixed-bed resid service. It is applied in the front-end of resid hydrotreaters due to its enhanced ability to remove metals and asphaltenes and to ...

TK-743 catalyst

A demetallization catalyst with moderate hydrodesulfurization (HDS) activity for fixed-bed resid service and vacuum gas oil (VGO) hydrotreating.

TK-753 catalyst

A transition catalyst in fixed-bed resid hydrodesulfurization (HDS) systems. It delivers a high capacity for uptake of nickel and vanadium and a low bulk density.

TK-773 catalyst

A final-stage catalyst for fixed-bed resid hydrodesulfurization (HDS) units. It delivers a high capacity for uptake of nickel and vanadium, together with a low bulk density.

TK-831 catalyst

This catalyst provides high hydrodemetallization (HDM) activity, metal storage capacity and moderate hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) activity.
