A fluidized reactor system includes a reactor containing a fluidized bed situated above a distributor plate arranged within the reactor, a fluidizing gas fed into the fluidized bed via the distributor plate to cause uniform fluidization of the fluidized bed and promote creation of solid polymeric granules, and a valve assembly penetrating a sidewall of the reactor to remove a mixture of the fluidizing gas and the solid polymeric granules from the fluidized bed. The valve assembly is coupled to the sidewall at a downward angle relative to the sidewall such that an upward-facing opening of the valve assembly extends into the fluidized bed.

An eductor, a process and apparatus for gas phase polymerization of olefins in a polymerization reactor are disclosed. The process and apparatus employ an eductor which has an inlet which makes a bend of less than about 90 toward the outlet after entering the mixing chamber of the eductor.

Herein disclosed is a dry reforming reactor comprising a gas inlet near the bottom of the reactor; a gas outlet near the top of the reactor; a fluidized bed comprising a catalyst; and one or more hydrogen membranes comprising palladium (Pd). In some cases, the one or more hydrogen membranes comprises Pd alloy membranes, or Pd supported on ceramics or metals. In some cases, the one or more hydrogen membranes are placed vertically in the reactor as hydrogen membrane tubes hanging from the top of the reactor. In some cases, the hydrogen membranes are configured to selectively collect hydrogen from the tubes via one or more internal manifolds and sent to an external hydrogen collection system.

The disclosure provides a flushing process for removing polymer fouling from a reactor including a gas distributor proximal to the bottom thereof and an internal condenser proximal to the top thereof, the method including, for a first flushing time period, injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the internal condenser to induce an upward movement of flushing solvent, the withdrawn flushing solvent containing a first polymer content. After the first flushing time period is complete, for a second flushing time period, the process includes injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the gas distributor to induce a downward movement of flushing solvent, the withdrawn flushing solvent containing a second polymer content.

In a method for the hydrolysis of liquid, organic substrates (1), the substrate to be hydrolysed is introduced into a circulation loop for heating, where an equal amount of hydrolysed substrate (1) is displaced from the circulation loop (6, 7, 8, 9). An appropriate system can have a circulation loop, a feed device, a circulation pump for generating a circulation flow in the circulation loop, and a heater for heating and reheating the circulation flow.

Systems for separating a contaminant trapping additive from a cracking catalyst may include a contaminant removal vessel having one or more fluid connections for receiving contaminated cracking catalyst, contaminated contaminant trapping additive, fresh contaminant trapping additive, and a fluidizing gas. In the contaminant removal vessel, the spent catalyst may be contacted with contaminant trapping additive, which may have an average particle size and/or density greater than the cracking catalyst. A separator may be provided for separating an overhead stream from the contaminant removal vessel into a first stream comprising cracking catalyst and lifting gas and a second stream comprising contaminant trapping additive. A recycle line may be used for transferring contaminant trapping additive recovered in the second separator to the contaminant removal vessel, allowing contaminant trapping additive to accumulate in the contaminant removal vessel. A bottoms product line may provide for recovering contaminant trapping additive from the contaminant removal vessel.

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 an outer sidewall and a bottom wall enclosing a hollow chamber comprising a lower fluidized bed zone and an upper freeboard zone. A plurality of inlets is provided for injecting at least one fluidizing medium into the fluidized bed zone and creating a swirling flow. At least one feed inlet communicates with the fluidized bed zone; and at least one product outlet is provided for removing a product from the chamber, the outlet(s) communicating with either the fluidized bed zone or the freeboard zone. The reactor has at least one internal barrier located inside the hollow chamber, and at least partly located in the fluidized bed zone. The internal barrier(s) have at least one opening within the fluidized bed zone, such as an underflow opening, to permit internal recirculation of material from the product zone to the feed zone, thereby simplifying reactor structure.
