ACT 153 has been specifically developed to mitigate the pressure drop issues in the first stage of pygas hydrogenation and consequently to extend the cycle length of the unit.It is used as top bed grading material upstream the main catalytic bed in the first stage of pygas hydrogenation.
ACT 153 acts as a mild activity hydrogenation catalyst thanks to its low palladium content, ensuring smooth hydrogenation reaction on the top part of the bed where crust is frequently found and displaying excellent performances in combination with palladium based catalyst. The bead shape makes it easy to handle. Its size allows to create a gradient of particle size at the top of the reactor. The attrition resistance is particularly high.
