Abstract: A method of controlling particle additions to a fluidized bed reactor includes measuring pressure fluctuations inside the fluidized bed reactor over a selected time period, determining a pressure parameter indicative of amplitudes of the pressure fluctuations, comparing the pressure parameter to a specified threshold, and controlling particle additions to the fluidized bed reactor when the pressure parameter deviates from the specified threshold.
