REC Silicon has developed the unique Fluidized Bed Reactor (FBR) silicon refining process, a next-generation method of refining silicon. With the FBR process, we can produce solar-grade silicon at a lower cost, while using 80-90 percent less energy than the traditional Siemens method for converting silane gas to high purity silicon. The movie below shows the operation of a fluidized bed reactor. Before the reactor is started the catalyst pellets lie on a grate at the bottom of the reactor. In an FBR, monosilane (silane for short) is injected through nozzles at the bottom of the reactor to form a fluidised bed that carries silicon seed particles fed from above.
Despite challenges related to purity and efficiency, low-cost fluidized bed reactor (FBR) manufacturing technology is expected to make significant gains in the market for solar polysilicon during the next few years, according to a new report from IHS Technology.

Fluidized-Bed Reactor As opposed to fixed-bed reactors, fluidized-bed reactors contain their catalyst material in a fluid state. Current Applications for Fluidized Bed Reactors. While fuels from petroleum processing are the major applications of FBR technology, there are numerous other applications, from Plastics to Rubber.

Fluidized Bed Reactor Technology Claims A Place In Solar Polysilicon Manufacturing
CaO has been deposited on a nanosilica powder matrix by a procedure based on atomic layer deposition (ALD) in a fluidized bed reactor at atmospheric pressure following a potentially scalable process. At present, fluidized bed technology appears to have maximum potential in producing high-quality bio-oil. A model of wood pyrolysis in a fluidized bed reactor has been developed. The performance of two laboratory-scale fluidized bed reactors with natural zeolite as support material when treating high-strength distillery wastewater was as. For a broad range of influent flow rates and contaminant concentration levels, our fluidized bed reactor (FBR) system is often the most economical treatment choice. Anaerobic treatability of a real cotton textile wastewater was investigated in a fluidized bed reactor (FBR) with pumice as the support material. The immobilized biomass or attached volatile solids level on the support material was 0.
