Abstract
The activities of monometallic Pt-, Ru-, and Rh-containing catalysts supported on Al2O3, Al2O3—F, SiO2, WO3/ZrO2, and La2Î3/ZrO2, in cyclohexane ring opening to form n-hexane were studied. The most active catalyst is Rh/Al2O3. Cyclohexane hydrogenolysis to n-hexane also occurs over the Pt/Al;>2O3 and Pt/La2Î3/ZrO2 catalysts. Ring opening over the Ru catalysts proceeds at significantly lower temperatures (210—230 °C) than over the Pt and Rh catalysts (350—400 °C), but the ruthenium systems are less selective for n-hexane formation than Rh/Al2O3 catalysts. The effects of acid-basic properties of the support and the reaction conditions on the activities of the catalytic systems in cyclohexane ring opening was studied.
