The catalyst of XY-S made in China and catalyst of Ucat-Jlp25 made in Unipol were mixed in a proportion to reactor continuously in the plant from Unipol for full density polyethylene （FDPE）. The specific raw material consumption for polyethylene products of DFDA7042, DFDA7042N, DFDA7042H were calibrated by parameters controlled such as reaction temperature, ethylene partial pressure, proportion of hydrogen to ethylene, butane to ethylene, titanium to aluminum, performances and quality of the products tested. The disadvantages of XY-S were found, the improvement measures in process control proposed, and valuable experience provided for domestic catalyst applied in the plant.
