METHOD OF PRODUCING POLYETHYLENE AND POLYETHYLENE THEREOF |
| 摘要 |
A system and method of producing polyethylene, including: polymerizing ethylene in presence of a catalyst system in a reactor to form polyethylene, wherein the catalyst system includes a first catalyst and a second catalyst; and adjusting reactor conditions and an amount of the second catalyst fed to the reactor to control melt index (MI), density, and melt flow ratio (MFR) of the polyethylene. |

1. A method of producing polyethylene, comprising:
polymerizing ethylene in presence of a catalyst system in a reactor to form polyethylene, wherein the catalyst system comprises a first catalyst and a second catalyst; and adjusting reactor conditions and an amount of the second catalyst fed to the reactor to control melt index (Mi) and density of the polyethylene based on a target melt flow ratio (MFR) and a desired combination of molecular weight distribution (MWD) and composition distribution (CD) of the polyethylene. |
