FLUORINATED CATALYST SUPPORTS AND CATALYST SYSTEMS

摘要

Catalyst systems and methods for making and using the same. A method for making a catalyst support includes forming a mixture of a support material and a fluoride donor. The mixture is added to a fluidized bed reactor. The mixture is fluidized to form a fluidized bed while maintaining a flow rate of a fluidizing gas of about 0.1 ft. / sec at less than about 370 °C and greater than about 0.35 ft./ sec at temperatures greater than about 370 °C. The mixture is calcined to decompose the fluoride donor, forming a fluorinated support.
