Effects of Catalyst Activity Profiles on the Scale-up of Polymerization Reactors

摘要

The aim of this paper is to demonstrate a method that is able to transform information observed by laboratory experiments with catalysts possessing changing activity to continuous industrial reactor. The method is based on the fact that the change of catalyst activity and quality properties of the polymer can be determined as functions of the catalyst age based on laboratory polymerization experiments carried out for different time periods. This information integrated with the residence time distribution of the industrial reactor can be used to estimate the average properties of the polymer powder produced in the continuous industrial reactor. The methed is demonstrated in case of ethylene polymerization.
