What is an appropriate density of steam for control in the pre-raising stage?

We use 500 kg/h of dry gas for pre-lifting.

The inner diameter of the pre-lift section is 1.5 m, with a gas flow rate of 10 t/h (steam + dry gas)

There is no completely suitable universal standard for the pre-heating steam volume. Generally, the adjustment is made based on a density of around 400 kg/m2 in the pre-lifting section. But a major prerequisite is to ensure normal catalyst fluidization.
