More Information
Summary:The invention relates to a method of operating a polyolefin reactor system, comprising:feeding a chromium-based catalyst through a mixer to a polymerization reactor;adding a reducing agent to contact the chromium-based catalyst through the mixer to the polymerization reactor; andpolymerizing an olefin into a polyolefin in the polymerization reactor in presence of the chromium-based catalyst.
