Hydrocracking | Hydrocracker feed pretreatment

Unmatched high HDN and HDS activity

The growing interest in processing heavy oils with high nitrogen content has created a need for pretreatment catalysts with even higher hydrodenitrogenation (HDN) and hydrodesulfurization (HDS) activity. Without such pretreatment, organic nitrogen compounds would poison downstream hydrocracking catalysts and drive up costs by negatively impacting not only conversion and yield structure but also cycle length and product properties.

Proprietary HySwell™ and HyBRIM™ technologies enable our hydrocracker feed pretreatment catalysts to deliver unmatched high activity for HDS and, in particular, HDN. As the high activity protects the downstream hydrocracking catalyst, a lower catalyst density – thanks to improved utilization of active metals and modiﬁed carriers – reduces fill costs, amounting to significant savings for your refinery.

Catalysts for hydrocracker feed pretreatment

TK-971 catalyst

TK-971 provides balanced naphtha and middle distillate yields minimizing overcracking. It is ideal for flexible operations.

TK-951 catalyst

TK-951 is a high-activity hydrocracking catalyst, providing optimum diesel and naphtha yields, while minimizing overcracking.

TK-961 catalyst

TK-961 is a zeolitic NiW based hydrocracking catalyst with very high activity and a very high nitrogen tolerance.

Catalyst support

Our Catalyst Support is designed to support the combined weight of the catalyst, support material and oil. It can also withstand pressure drop over the catalyst bed during the entire catalyst ...

Inlet diffuser

Our Inlet Diffusers are designed to uniformly deliver gas and liquid to the distribution tray below, while keeping the liquid on the tray level.

Scale catcher

Our Scale Catching technology is a cost effective solution to delay pressure drop development and significantly increase unit utilization. Also reduces the amount of top grading material needed.

Outlet collector

Our Outlet Collector ensures even flow distribution in the bottom bed to maximize catalyst utilization and prevents bed migration to downstream piping and equipment.

Quench mixer

Our Quench Mixer ensures efficient mixing of catalyst bed effluents from both above and from the cold quench stream.

Redistribution tray

Our Redistribution Tray ensures uniform redistribution of the mixer effluents to the catalyst bed.

Distributor tray

Our Vapor Lift Distributor Tray (VLT) ensures uniform distribution of liquid and gas over the entire cross section area of the catalyst bed.

HPNA Trim™

Cost-effectively manage HPNAs in full conversion hydrocrackers by taking advantage of the heavy HPNA compounds' extremely high boiling points.
