ABSTRACT:
The operation of a fluid-bed reactor in which the catalyst has a proclivity to stickiness deleterious to efficiently carrying out a reaction of the gaseous components fed to the reactor, is controlled by monitoring the fluctuations in temperature at various locations in the bed, and computing the standard deviation of temperature at predetermined intervals of time. When the fluid-bed consists essentially of a supported catalyst performing at peak efficiency, near which it has a proclivity to "stickiness", slight fluctuations, less than 1.degree. F., of operating temperature are correlatable to the quality of fluidization and the risk of an uncontrollable upset in the reactor.
