  • Process for selecting shaped particles, a process for installing a system, a process for reacting a gaseous feedstock in such a system, a computer program, a computer program product, and a computer system
    Publication number: 20060065064
    Abstract: A process for selecting shaped particles for use in a tube which is capable of being packed with shaped particles to form a packed bed in the tube. A desired value of one or more properties of the packed bed is defined. The dimensions of the shaped particles are calculated such that a packed bed in the tube of the shaped particles having 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 by shaped particles, the packing density, and the resistivity for a gas flowing through the packed bed.
