Avoiding fouling problems

Combating reactor bed fouling

Catalyst bed fouling reduces the void volume in the reactor, leading to pressure drop build-up, channeling, and hot spots. These issues negatively affect the catalyst performance and, thus, the cycle length of the unit.

From our proven grading strategies to our shape-optimized toppings, particulate traps and high void fraction ring-shaped catalysts, Topsoe offers a wide range of solutions for combating reactor bed fouling. Our solutions are based on unmatched industry experience and advanced laboratory modelling and are individually tailored to your needs.

A common problem in hydroprocessing reactors, is pressure drop build-up caused by various particles plugging 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.

Applications within this area

Crust formation

Topsoe’s catalyst grading solutions prevent crust formation by gradually increasing the catalytic activity from low in the inert topping to higher, the further down the bed you go.
