Abstract

A reactor and process for reducing the probability of ignition in fluid bed-catalysed oxidation reactions in which a molecular oxygen-containing gas is fed into a region of a fluidised catalyst bed having a higher time-averaged catalyst particle density higher than the fluidised catalyst bed as a whole.
