Catalyst feed systems and processes utilizing such systems are described herein. Some embodiments disclosed herein relate to a process for improving the flowability of catalyst in a catalyst feed system, including providing a catalyst feed vessel with at least one heat exchange system for maintaining the catalyst system temperature below a critical flow temperature. Also disclosed is a catalyst feed system for the polymerization of olefins including a catalyst feed vessel; and a heat exchange system for maintaining a temperature of a catalyst within the catalyst feed vessel. Additionally disclosed is a process for polymerization of olefins including maintaining a supported catalyst in a catalyst feed vessel below a critical flow temperature of the catalyst; feeding the catalyst to a polymerization reactor; and contacting the catalyst with an olefin to form a polyolefin.
A process for improving the flowability of a heteregenous solid or supported catalyst system in a catalyst feed system, wherein the catalyst system undergoes particulate flow through the catalyst feed system, comprising providing a catalyst feed vessel with at least one heat exchange system for maintaining the catalyst system at a temperature of 27° C. or less and below a critical flow temperature.
A process for polymerization of olefins comprising:
