In some embodiments, the reactor has a cooling control loop having a natural frequency and the frequency components removed during step (c) include a frequency component whose frequency is the natural frequency. In some embodiments, step (a) includes the step of generating at least two sets of skin temperature data, each indicative of skin temperature as a function of time at a different elevation within the fluidized bed. Some embodiments enable diagnosis of poor fluidization or mixing in the bed of a fluidized bed reactor, by analyzing Fourier-transformed, filtered skin temperature data.
