A device for bringing a target medium into contact with a carrier fluid comprises a chamber comprising a circumferential wall, a bottom wall and a top wall forming an enclosure for containing the target medium while contacting the carrier fluid, the chamber being substantially rotationally symmetric with respect to an axis of symmetry and adapted for remaining mechanically static in operation of the device. The device comprises a fluid inlet for injecting the carrier fluid into the chamber in a substantially tangential direction with respect to an inner surface of the circumferential wall, and an outlet. The device comprises a fluid distributor in the chamber for enabling the injected carrier fluid to pass through the distributor in a substantially inward radial direction, the distributor being substantially rotationally symmetric and adapted for rotating around the axis when driven by a transfer of momentum between the injected carrier fluid and the distributor.

An apparatus for forming an electrode film mixture can have a first source including a polymer dispersion comprising a liquid and a polymer, a second source including a second component of the electrode film mixture, and a fluidized bed coating apparatus including a first inlet configured to receive from the first source the dispersion, and a second inlet configured to receive from the second source the second component.

A reactor comprises a reactor vessel defining a confined reactor volume, a support assembly extending about a periphery of the confined reactor volume, a basket positioned within the reactor vessel and supported by the support assembly, the basket having an interior surface and an exterior surface, a downflow zone being defined between the exterior surface of the basket and an interior surface of the confined reactor volume, an inlet screen positioned adjacent to one end of the interior surface and an outlet screen positioned adjacent to an opposite end of the interior surface, an upflow zone defined between the inlet screen and outlet screen, the inlet screen and the outlet screen containing a quantity of particulate catalyst, and a circulating device positioned above said upflow zone and configured to continuously circulate fluid upwardly though said upflow zone and downwardly through said downflow zone, the support assembly and the basket configured to promote the formation of a fluid vortex within a portion of the downflow zone.

A device with annular spouted fluidized bed can be used for carrying out the majority of the technical processes carried out in fluidized bed devices. The reaction chamber of the device has, throughout at least a part of its height, a downwardly tapering funnel shape with step-structured inner surface. The shape of the reaction chamber, together with the tangential admission thereto of fluidized and other gases, makes it possible to create, in the reaction chamber, an adjustable toroidal fluidized bed, in which the rotation rate of the particles of the material undergoing treatment can be adjusted in both horizontal and vertical planes, and also makes it possible to control the dwell time of particles of different sizes in the reaction zone, the intensity with which materials are treated, and other process parameters.

A device for processing a flow of particulate material by contact with a gas flow includes a housing defining a processing chamber. This chamber includes a gas distribution plate having openings. The gas distribution plate separates a lower gas plenum from a solid-gas contact zone. The contact zone has at least one cylindrical partition upstanding from the gas distribution plate dividing an inner section from an adjacent annular outer section. The at least one partition is provided with a transfer opening for the particulate material. The housing is also provided with an inlet for supplying particulate material to the inner section and an outlet for discharging processed particulate material from the annular outer section.

A fluid-solids contactor comprising an annular rotating fluidized bed and a method of using the same are disclosed. The fluid-solids contactor includes a vessel and a plurality feed inlets disposed thereon. The vessel comprises a stationary inner wall, an outer wall, and a chamber formed between the stationary inner wall and the outer wall. The feed inlets are configured to create an annular rotating bed with mixture of solids and a fluid when the solid particles and a fluid are fed into the chamber. The stationary inner wall of the vessel is permeable to the fluid such that the fluid from the chamber can be continuously withdrawn from the solids to the space within the stationary inner wall of the vessel.
