  • Regeneration of a dehydrogenation catalyst
    Patent number: 6916756
    Abstract: A process for regenerating a dehydrogenation catalyst comprises the steps (a)-(f): (a) flushing with inert gas at a pressure of from 0.5 to 2.0 bar and a gas hourly velocity of from 1000 to 50 000 h?1; (b) passing an oxygen-containing gas mixture comprising an inert gas through the catalyst at a pressure of from 2 to 20 bar and a gas hourly velocity of from 1000 to 50 000 h?1 for from 0.25 to 24 hours while increasing the oxygen concentration stepwise or continuously from an initial value of from 0.01 to 1% by volume of O2 to a final value of from 10 to 25% by volume of O2; (c) optionally passing an oxygen-containing gas mixture comprising an inert gas through the catalyst at a pressure of from 0.5 to 20 bar and a gas hourly velocity of from 10 to 500 h?1 for from 0.25 to 100 h, with the oxygen concentration being from 10 to 25% by volume of O2; (d) optionally changing the pressure repeatedly, rapidly and in opposite directions by a factor of from 2 to 20 within the range from 0.
