1. The dehydrogenation and hydrogenolysis of cyclohexane have been investigated on a catalyst consisting of 5% ruthenium on silica at 250-300°. The temperature dependence of the rate of these reactions shows a discontinuity in the region of 300-320° for the former, and 300-330° for the latter. 2. The activation energy for the dehydrogenation of cyclohexane has been found to be 9.2 kcal/mole for 250-300°, and 16.65 kcal/mole for 320-350°, For the hydrogenolysis of cyclohexane the activation energy has been found to be 12 kcal/mole at 250-300° and 26.6 kcal/mole at 330-350°. 3. The relative adsorption coefficients of benzene have been determined during the dehydrogenation of cyclohexane in the temperature range 250-300°. 4. The rate of the hydrogenolysis of cyclohexane may be described by the equation: v=kPC6H120.675 · PH20.955. 1964 Consultants Bureau Enterprises, Inc.
