Progress in technology and catalysts for CX kettle-type slurry HDPE process

The slurry polyethylene CX process developed by Mitsui Petrochemical Company (MPC) in Japan has the advantages of advanced controlling technology,reasonable process layout,and quick polyethylene brand transition.The slurry polyethylene CX process,one of widely used polyethylene production processes,is mainly used for the production of high density polyethylene (HDPE).CX process flow of MPC for HDPE production was introduced.The characteristic and disadvantages of different catalysts for this slurry process were summarized and compared,including PZ and RZ catalysts of MPC,BCH and BCE catalysts of Sinopec Beijing Research Institute of Chemical Industry,XY-H catalysts of Liaoning Xiangyang Chemicals Group,NT-1 catalyst of Sinopec Research Institute of Petroleum Processing and PSE-101 catalyst of PetroChina.Some suggestions of the development and application of HDPE catalysts for the slurry process in China are proposed.
