摘要： A method for preventing or reducing agglomeration and/or accumulation on or around the gas distribution grid in a fluidized-bed vessel. The method involves introducing one or more scouring balls into the vessel above the gas distribution grid, and carrying out a fluidized-bed process in the presence of the scouring balls.

摘要： A process for preventing or reducing polymer agglomeration and/or accumulation on or around the gas distribution grid in an olefin polymerization, fluidized-bed reactor. The process involves introducing one or more scouring balls into the reactor above the gas distribution grid, and carrying out olefin polymerization in the presence of the scouring balls. Also disclosed is a process for polymerizing olefins in a fluidized-bed reactor with reduced polymer agglomeration and/or accumulation on the gas distribution grid.
