Abstract: Provided is a method for continuous production of zeolite in which a starting material is continuously supplied to a tubular reactor to produce an aluminophosphate zeolite that contains, in the framework structure, at least aluminum atoms and phosphorus atoms or an aluminosilicate zeolite having 5≤SiO2/Al2O3≤2000. The tubular reactor is heated using a heat medium; a ratio (volume)/(lateral surface area) of the volume (inner capacity) to the lateral surface area of the tubular reactor is 0.75 cm or smaller; and seed crystals are added to the starting material. Through using a small-diameter tubular reactor and heating with a heat medium, it becomes possible to heat sufficiently the entirety of a starting material (zeolite precursor gel) in a short time, and to allow reaction to proceed at a high rate. The occurrence of irregular pressure fluctuations during continuous production of the zeolite can be prevented by adding seed crystals.

Abstract: A packing system is disclosed that has a series of flat blades arranged to promote mixing in a fluidized bed such as one in a FCC stripper, with an upward flowing gas stream and a downward flowing solid particle stream. The blade arrangement provides for different gas solids flow directions within a single layer of packing system to enhance cross mixing of gas and catalyst in all directions and reduces the potential for gas and catalyst bypassing. The blade arrangement has splits which minimizes the tendency for phase separation around the blade. The arrangement and sizing of the blades is intended to promote intimate contact between the two phases to ensure efficient mass transfer of material trapped inside the particles to the gas phase. The arrangement of the blades prevents excessive bubble growth and channeling, both of which reduce surface area for mass transfer.

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.
