What is the maximum pressure difference in a fixed-bed reactor that can be considered as evidence of coking of the catalyst in that fixed bed?

What is the basis for 15 percent?
This depends on the height of the catalyst bed and the amount of catalyst loaded. Under stable feedstock and pressure conditions, a pressure difference of more than 0.2 MPa is generally considered to indicate catalyst coking. Additionally, there are also single-point trend charts for the pressure difference, which can be examined.
This is just a purely empirical number, right???
