摘要： A fluidized bed reactor system utilizes a fluid phase, a retained fluidized primary particulate phase, and a migratory second particulate phase. The primary particulate phase is a particle such as a gel bead containing an immobilized biocatalyst. The secondary particulate phase, continuously introduced and removed in either cocurrent or countercurrent mode, acts in a secondary role such as a sorbent to continuously remove a product or by-product constituent from the fluid phase. Introduction and removal of the sorbent phase is accomplished through the use of feed screw mechanisms and multivane slurry valves.

摘要： The black powder to be treated is injected into the bottom portion of a heated dense fluidized bed, said bed having effective depth enabling the carbon the particles of silica to be oxidized into carbon dioxide as the particles go through the dense fluidized bed while being entrained by the fluidization air. The whitened powder is then recovered by filtering the gases leaving said dense fluidized bed. The invention is particularly applicable to the cosmetics industry for producing make-up that uses silica powder.

摘要： For processing matter in a turbulent mass of particulate material, a substantially annular processing region (14; 104; 206) is provided and is preferably in the form of a substantially annular processing chamber having a radially inner wall which includes a waist (38; 122). A flow of fluid and matter to be processed are admitted to the processing region through one or more inlets (28, 46; 108, 124; 214, 220) with the flow of fluid being directed generally circumferentially into the processing region. In the processing region, matter to be processed is embedded in a compact turbulent band of particulate material for processing. Once processing is complete, the processed matter is withdrawn from the processing region, preferably by entrainment in an exhaust flow of the fluid.

摘要： A selected fraction of solid particles having sizes, densities and/or weights in a selected range is separated from a mixture of articles by fluidizing the mixture in a bed using a fluidizing fluid to cause particles including the selected fraction to pass out of the top of the bed; conveying the particles in a conveying fluid to a suitable separator (e.g. a cyclone) wherein the selected particles fraction is separated from smaller, lighter particles; injecting the separated fraction from the separator into a utilization zone (e.g. a fluid bed reactor); entraining other particles in the conveying fluid to another separator (e.g. a cyclone) to produce solids-free conveying fluid which is recirculated for re-use. The original particles mixture may be obtained by separation (e.g. in a cylone) from fluid leaving the utilization zone.

摘要： A method of operating a fluidized bed system, typically as a combustor system for power or steam generation by burning high-sulfur coal, which comprises forming an entrained fluidized bed in a first space region containg a first solid bed particle component, such as a hematite ore containing over 90% Fe.sub.2 O.sub.3, or limestone, forming in a more limited space region within the first region a dense fluidized bed containing a second solid bed particle component, such as larger particles of the hematite, essentially comprising a material having long-term physical and chemical stability in the fluidized bed system so as to be substantially non-agglomerating and not subject to substantial attrition therein, providing a recirculation path such as through a cyclone separator and particle reservoir for the first particle component from the first space region through the dense fluidized bed in the more limited space region, and operating the fluidized bed system at a velocity such that the second component particles are effectively retained in the dense fluidized bed in the more limited space region, whereas the first component particles recirculate and interpenetrate therethrough, commingling with the second component particles.
