ROLE OF CATALYST PREPARATIONS FOR THE REMOVAL OF ENVIRONMENTAL HAZARDS (Published)

The kinetics of heterogeneous catalytic conversion of cyclohexane over Cu supported active carbon catalysts at 280-380 0C and time of contact 13.63-6.52 min were studied in flow system under normal pressure . The solids were prepared by impregnation of Cu and active carbon which was treated by phosphoric acid of percent ratio 5,10and 15% producing CuACPI ,CuACPII and CuACPIII respectively . The prepared solids were characterized by TG A , DTA, X-ray diffraction pattern and BET surface area measurements. The catalytic activity of the prepared catalysts was studied for the conversion of cyclohexane at temperature ranging from280 -380o C by using flow system techniques, the liquid and gaseous products were analyzed by gas liquid chromatography .The catalytic activity and selectivity toward toluene formation over the catalysts of Cu supported on an active carbon were investigated . Adsorption isotherm terms for the prepared solids and their application for the removal of different heavy metal ions were studied
