A process and apparatus for fluidizing a catalyst cooler with fluidization gas fed to the cooler below the catalyst bed is disclosed. Fluidization headers extend through an outlet manifold and deliver fluidization gas through distributors protruding through an outlet tube sheet defining said outlet manifold. The outlet manifold collects heated water vapor from the catalyst cooler and discharges it from the catalyst cooler.

Contamination of fluidized bed-produced polycrystalline granules by phosphorus is reduced by employing as seals and/or packings, graphite containing <500 ppmw of phosphorus.

An apparatus for processing graphite particles is disclosed. The apparatus may comprise an electromagnetic radiation emitting device including a microwave device coupled to the reaction chamber for the creation of electromagnetic waves, the electromagnetic waves comprising microwaves. The apparatus may also comprise an inlet attached to the reaction chamber for introducing graphite particles, and an outlet attached to the reaction chamber for allowing processed graphite particles to exit the reaction chamber. The graphite particles in the reaction chamber thermally altered by exposure to the electromagnetic radiation such that the graphite particles are heated

The present disclosure discloses a fluidized bed cooler with regional coordination enhancement, comprising a shell, a catalyst inlet, an interior of the shell is divided into a catalyst inlet influence region, a dilute phase region, a dense phase region and a gas distributor influence region; a catalyst inlet inclined tube is provided obliquely upward at the catalyst inlet, and a regional particle distributor is provided at the catalyst inlet; the dense phase region is provided with a plurality of dense phase baffle plates, and the dilute phase region is provided with a plurality of dilute phase baffle plates; and the gas distributor influence region is provided with double gas distributors.

A system for the production of a polycrystalline silicon product is disclosed. The system includes a reaction chamber, a susceptor, an induction unit, and a plurality of energy sources. The reaction chamber has a reactor wall, and the susceptor encircles the reactor wall. The induction heater surrounds the susceptor, and has multiple induction coils for producing heat in the susceptor. The coils are grouped into a plurality of zones. The plurality of energy sources supply electric current to the coils. Each energy source is connected with the coils of at least one zone.

A system includes a standpipe for receiving a flow of solids therethrough, the standpipe having at least one inlet configured to receive a gas for decreasing a solids-to-gas ratio of the flow, a sealpot having an inlet fluidly coupled to the standpipe and an outlet fluidly coupled to a riser, the sealpot being configured to fluidize the solids received from the standpipe and to transport the solids to the riser, and a drain device fluidly coupled to an outlet in the standpipe, the outlet being located upstream from the inlet of the sealpot. The drain device is configured to remove the excess gas from the flow of solids within the standpipe to increase the solids-to-gas ratio of the flow prior to the solids entering the sealpot.

An apparatus for controlling flow of a material includes an inlet for receiving the material from a source, and a seal mechanism connected to the inlet, the seal mechanism having a fluidizing bed configured to receive the material from the inlet, a first discharge passageway and a second discharge passageway. The fluidizing bed includes a first transport zone associated with the first discharge passageway and a second transport zone associated with the second discharge passageway, wherein the first and second transport zones are configured to receive transport gas from a transport gas source. The transport gas is controllable to selectively divert a flow of the material into the first discharge passageway and the second discharge passageway.

The present invention utilizes a high-speed intensive mixer in a fluidizing-type, solid-phase, neutralization reactor to blend solid-state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste-like formation, extrusion, granulation, drying, and grinding, etc. The invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, plant space, and labor and energy costs. All of these factors coupled with increased productivity will drastically lower the overall production cost. Also, the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues.
