Process for the reactivation of platinum-on-alumina catalysts |
| abstract |
A process for reactivating or regenerating a catalyst of the platinum-on-alumina type, comprising the steps of: A. MAINTAINING THE CATALYST IN A REDUCING MEDIUM, PREFERABLY CONTAINING HYDROGEN GAS, AT A TEMPERATURE BETWEEN 400* C and 600* C, for a period of substantially 2 to 8 hours in a velocity of gas flow of 1 X 10 2 to 1 X 10 1 m3 of gas per hour and per kg of catalyst; B. HALOGENATING THE CATALYST THEREAFTER IN A REDUCING GAS MEDIUM AT A TEMPERATURE BETWEEN 400* C and 550* C with a gas-flow rate of 1 X 10 2 to 4 X 10 1 m3 of gas per hour per kg of catalyst using a halogenated organic compound with one to six carbon atoms per molecule and an atomic ratio of halogen:hydrogen no greater than unity and a partial pressure of this compound between 1 and 100 mm Hg for a period of one-half to 10 hours and in the presence of a moisture content of 10 to 50 ppm to bring the halogen content of the catalyst to 0.1 to 1 percent by weight; and C. OXIDIZING THE CATALYST TREATED IN STEP (B) WITH OXYGENCONTAINING GAS OF AN OXYGEN CONCENTRATION INCREASED FROM 0.2 TO ATMOSPHERE CONCENTRATIONS OVER A PERIOD OF 5 TO 15 HOURS AT A TEMPERATURE OF 400* TO 600* C and with a gas-flow velocity of 0.5 to 5 m3 per hour per kg of catalyst. |
