The fluidizing nozzle includes a nozzle tube limiting at least a part of a feed channel in which fluid is configured to flow, at least one fluid discharge opening arranged near a downstream end of the nozzle tube, and a pot-like hood, which sealingly closes the nozzle tube with a hood cover of the pot-like hood at the downstream end of the nozzle tube at which said at least one fluid discharge opening is provided. The feed channel is provided with a flow restriction element defining at least one flow restriction feed channel upstream of said at least one fluid discharge opening.

A combustor air bar grid for use within a fluidized bed reactor includes at least two main air collector bars in fluid communication with a source of fluidizing gas, a plurality of primary air bars that are transversal to the main air collector bars and arranged on the at least two main air collector bars such that the main air collector bars support them, and in fluid communication to at least two of the main air collector bars. The main air collector bars and the primary air bars define ash removal openings in the air bar grid and a plurality of fluidized nozzles are arranged to each of the primary air bars for fluidizing the bed reactor. A fluidized bed reactor includes such a combustor air bar grid.

Apparatus and methods for providing high velocity gas flow showerheads for deposition chambers are described. The showerhead has a faceplate in contact with a backing plate that has a concave portion to provide a plenum between the backing plate and the faceplate. A plurality of thermal elements is within the concave portion of the backing plate and extends to contact the faceplate.

System and methods for plasma treatment of a fluidized bed of particles are disclosed. The systems include an energy coupling zone configured to generate a plasma from microwave radiation and an interface element configured to propagate the plasma from the energy coupling zone to a reaction zone. The reaction zone is configured to receive the plasma, receive a plurality of reactant particles in a fluidization plane direction from a fluidization assembly positioned below the reaction zone, and form a product in presence of the plasma. The fluidization plane is substantially perpendicular to the propagated plasma.

Disclosed is a system and method for wirelessly monitoring 5 process conditions within a reactor vessel. A plurality of sensor-enabled radio frequency identification (RFID) tags are disposed at unspecified or random locations throughout a catalyst bed of a vessel and are used to measure various conditions within the vessel. The sensor-enabled RFID tags are encoded with individual identification codes and are wirelessly linked to multiple 10 transceivers. The use of multiple transceivers allows for the application of triangulation methods to identify the location of each of the sensor-enabled RFID tags in three dimensional space and for the interrogation of each sensor-enabled RFID tag to receive responsive transponder signals that carry information representative of the sensed condition within the reactor.

Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into light and heavy fractions utilizing convection heat from heaters used in steam cracking. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize either an ebullated bed reactor with extrudate catalysts or a slurry hydrocracking reactor using a homogeneous catalyst system, such as a molybdenum based catalysts which may optionally be promoted with nickel. Products from the upgrading operations can be finished olefins and/or aromatics, or, for heavier products from the upgrading operations, may be used as feed to the steam cracker.

A system and method thereof are provided for multi-stage processing of one or more precursor compounds into a battery material. The system includes a mist generator, a drying chamber, one or more gas-solid separators, and one or more in-line reaction modules comprised of one or more gas-solid feeders, one or more gas-solid separators, and one or more reactors. Various gas-solid mixtures are formed within the internal plenums of the drying chamber, the gas-solid feeders, and the reactors. In addition, heated air or gas is served as the energy source within the processing system and as the gas source for forming the gas-solid mixtures to facilitate reaction rate and uniformity of the reactions therein. Precursor compounds are continuously delivered into the processing system and processed in-line through the internal plenums of the drying chamber and the reaction modules into final reaction particles useful as a battery material.
