Patent abstract

The activity of a dehydrogenation catalyst is improved by increasing the water concentration maintained in the reactants toward the start of the catalyst's life, but after the catalyst has deactivated to the extent that the temperature required to maintain the conversion per pass of paraffinic hydrocarbon through the reaction zone increases by at least 2° C.
