KINETIC-STUDY OF THE REACTION BETWEEN MOLYBDENUM TRIOXIDE AND GASEOUSCARBON-TETRACHLORIDE

The kinetics of the chlorination reaction of molybdenum trioxide with gaseous carbon tetrachloride has been studied at temperatures between 713 and 753 K. The effects of temperature, reaction time, residence ti me and gaseous reactant concentration on conversion were studied throu ghout the reaction. In all cases, there was an increase in conversion when the above operating variables were increased. The kinetic model p roposed is consistent with and correlates the experimental data. In th e range studied for the different variables, the step that controls th e rate of reaction is the surface chemical reaction. Values of the rat e constant and the activation energy were estimated.
