  • Process for the activation of a supported chromium oxide based catalyst
    Patent number: 9006363
    Abstract: Process for the activation of a supported chromium oxide based catalyst in a fluidized bed activation reactor which has a catalyst bed being fluidized by a fluidization gas. The activation includes treatment at temperatures above 500° C., in which in an initial stage, where there is an initial temperature increase, the fluidization velocity (Vf1) of the fluidization gas is maintained below 6.5 centimeters per second (cm/sec) until the temperature inside the activation reactor reaches at least 200° C., and the fluidization gas is then brought to a value (Vf2) which is at least 1 cm/sec higher than Vf1.
