Abstract: A method of manufacturing core-shell particles comprises: filling a buffer into a rotor, which is extended in a longitudinal direction, and is accommodated so as to be spaced apart from an inner wall side of a non-rotational hollow cylinder extended in a longitudinal direction and then discharging air to outside; rotating the rotor after terminating the filling; forming a core-shell precursor by supplying raw materials from a first storage and a second storage, which comprise a material forming a core, into an interior of the cylinder in which the rotor rotates; supplying a shell material for coating the core to the interior of the cylinder in which a core-type precursor is formed; separating a liquid comprising core-shell particles formed through the supplying into a solid and a liquid; and drying the core-shell particles obtained through the separating.

Abstract: A gas-solids reaction system is provided for improving product recovery in a multiple reactor reaction system. The solids of the product gas-solids flows from the multiple reactors are separated out in a separation vessel having a baffled transition zone. Additional product vapor is stripped from the solids as the solids pass through the baffled transition zone. The solids are then returned to the multiple reactors.

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.
