ABSTRACT:
Particle size is increased and particle size range is decreased, e.g. narrower particle size distribution obtained of very tiny inorganic catalyst fines, (particles), particularly olefin catalysts by working these fines with very small quantities of polytetrafluoroethylene (PTFE) powder in order to trap the fines in a web of PTFE submicroscopic fibers.
