The paper introduces an extension of the two intrinsic criteria for runaway in fixed bed catalytic reactors based on the occurrence of characteristic points in the temperature profile along the reactor, that were developed by Van Welsenaere and Froment. The criteria have been generalized in order to consider general order reactions and thermal gradients in the shell side of the reactor. Keeping their original simplicity, they can deal with the co-and counter-current flow models, treating the constant wall temperature case as a particular one.
