Under condensated state operation,the activity of catalyst was decreased due to existence of condensing agent.

Expatiated now day the world technical progress of PE activator,for the advanced PE production process and activator,the PE performance had made further improvement,and become more processing and forming,the new production technique includes doublet PE technique,new reactor configuration technique,condensation state and exceeding condensation state technique.

The requirements for the kinetics constants under the condition of condensation mode operation in a gas phase fluid-bed reactor was recommended,and the catalyst efficiency can be calculated according to the kinetics constant and the average residence tim.

After the industrial production of condensing techniquein the gas-phase LLDPE plant, the polyethylene companies using gas-phaseprocess have invented the MAO metal catalyst, which is in accordance withthe condensing technique and has be industrialized.
