摘要: Multiple components are selected, conveyed, and measured in a polymerization system. A control system adjusts the system variables to the desired values. Portions of the components can be fed to a pre-contactor before introduction into the polymerization reactor. The catalyst component concentrations and residence times are tightly controlled in the pre-contactor to affect product properties. The pre-contactor can be a single or multiple combinations of a CSTR or plug flow pre-contactors.

摘要: Catalyst residues of a transition metal compound and an organometalliccompound contained in a polymer slurry are deactivated by contact with anhydrous carbon dioxide. Preferably the contacting is carried out in a transfer line connecting the reaction zone with a zone of sufficiently lower pressure that flashing of diluent occurs in the transfer line to assure mixing of the carbon dioxide and the catalyst residues.

摘要: Techniques are provided for producing polymer particles of a size just slightly larger than the size of polymer fines. The technique may prevent or limit the occurrence of reactor fouls associated with large polymer particles. The technique also may provide a greater weight percentage of solids in the reactor. The desired polymer particle size may be achieved by employing a catalyst having particles of a size determined based on the expected catalyst productivity. In certain embodiments, the catalyst particle size may be determined based on the expected catalyst productivity, the polymer particle density, the catalyst particle density, and/or the polymer particle size.
