Claim:
1. A method of operating a fluidized bed coking reactor comprising: (a) feeding heated solid particles into the reactor at a selected mass flow rate (“S”) and forming a fluidized bed of the solid particles; (b) determining a degree of backmixing of the solid particles in the fluidized bed; (c) monitoring a temperature profile (“T”) in the reactor; (d) feeding a feed material onto the fluidized bed of the solid particles at a feed material set point feed rate (“F (e) determining an upper feed material feed rate (“F (f) comparing the feed material set point feed rate to the determined upper feed material feed rate and in response to determining that the feed material set point feed rate is greater than the upper feed material feed rate, adjusting the feed material set point feed rate so that the feed material set point feed rate is at or below the upper feed material feed rate.
