Laboratory testing and evaluation
of fresh Fluid Catalytic Cracking (FCC) catalysts involves two
steps - a deactivation step and a catalytic testing step. Much
attention has historically been given to improved methods for
laboratory performance evaluation in pilot plant testing, particularly
with respect to simulating
the reaction conditions of a commercial FCC riser. But deactivation
mechanisms which occurs is equally important ,and Vinci-Technologies gas
developed an efficient equipement for this purpose.
FSD- Fcc catalyst Steam Desactivation unit (ASTM D-4463-96)
The Steam Deactivation Unit is designed to simulate the hydrothermal deactivation of FCC catalysts in industrial units. Treatment of the FCC catalysts is done at high temperature under continuous (water) steam flow.
The proposed steaming method is based on ASTM method D-4463-96 : "Metals Free Steam Deactivation of Fresh Fluid Cracking Catalysts" The equipment allows to treat 1 catalyst, and can be optionally delivered for testing 4 different catalyst samples at the same time under completely independent conditions.
The unit is connected to an electrical rack for the control of the equipment (oven, electrovalves, temperature programming, test duration, etc..). Main specifications :
Nitrogen flow : 0 - 120 Sl/h (0 - 2 Sl/mn)
Waterflow : 0 - 200 ml/h (0 - 3.3 ml/mn)
Reactor volume : 50 ml
System operating pressure : Atmospheric
Max. oven temperature : up to 900 °C
