| Abstract: | Against problems existing on catalyst preparation and polymerization processes for 3000 t/a Polypropylene Carbonate （PPC） plant of CNOOC, several optimization methods are suggested to improve the catalyst preparation and polymerization processes. These improved processes include solvent synthesis of diethyl zinc, highly efficient supported ternary rare-earth-metal coordination catalysts and hot feed of propylene oxide, combined use of them can increase yield of catalyst and catalytic efficiency on ternary rare-earth-metal coordination catalysts. Also the production technology of PPC is improved. |
