    摘要: The present disclosure is directed to an apparatus and process for producing a catalyst composition and a low-fines catalyst composition in particular. A crossflow classification device is used to separate large catalyst particles from catalyst fines, A slurry of a catalyst composition is introduced into the crossflow classification device. A classified catalyst composition is retrieved from a retentate produced as a result of subjecting the catalyst slurry to a crossflow classification process. The solids content of the pre-classified and/or post-classified catalyst slurry is determined by way of NMR spectroscopy. The solids content determination accounts for migration of wash liquid from the catalyst composition and into the slurry liquid phase, The classified catalyst composition has a low-fines content and produces a polyolefin composition with a low polymer fines content.
