摘要

A process for selecting shaped particles for use in a tube which is capable of beingpacked with shaped particles to form a packed bed in the tube. A desired value ofone or more properties of the packed bed is defined. The dimensions of the shapedparticles are calculated such that a packed bed in the tube of the shaped particleshaving the calculated dimensions meets or substantially meets the desired value(s),and shaped particles are selected in accordance with the calculated dimensions.The properties of the packed bed may be the volume fraction which is occupied byshaped particles, the packing density, and the resistivity for a gas flowingthrough the packed bed.
