Metal supported powder catalyst matrix and processes for multiphase chemical reactions
A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

TUBULAR REACTOR WITH MIXING MEANS
A process and apparatus wherein a process material comprising two or more distinct phases are fed continuously to a tubular reactor containing an agitator wherein as the phases flow along the reactor the agitator displaces at least part of a first phase from its natural position to within a second phase where it is distributed within the second phase by the agitator and the agitator is designed to allow the first phase that is distributed within the second phase to flow naturally back towards its natural distinct position within the reactor as the phases pass through the reactor, useful for mixing and/or reacting liquid/liquid; gas/gas and liquid/gas mixtures as well as solid liquid mixtures.
REACTION MIXER
An agitator or mixer installed in a solid-liquid-gas/slurry reactor in which gas removal from the slurry and foam destruction is promoted. The reaction mixer includes a vessel and an agitator assembly. The vessel is for containing the solid-liquid-gas mixture and defines two mixing zones within a given volume; a first mixing zone and a second mixing zone located above the first mixing zone. The agitator assembly is positionable within the vessel and comprises a rotatable shaft and a first and second impeller coupled to the shaft. The first axial impeller is locatable within the first mixing zone and is configured to pump the liquid in a downward direction along a vertical axis of rotation. The second impeller is locatable within the second fluxing zone and is configured to pump the liquid in an upward direction along the vertical axis of rotation.

Reactor comprising a nozzle for cleaning fluid, a kit and a method
The invention refers to a reactor and a method respectively for performing, by means of solid reaction members, a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media, and a subsequent cleaning of the reactor, said reactor comprising a vessel (11) in which a transformation device (100) has been mounted. The invention also refers to a reactor kit comprising such reactor. The reactor comprises at least one nozzle (15) arranged on the longitudinal inner wall of the vessel (11). The at least one nozzle (15) is arranged to direct a flow of a cleaning fluid (CF) in a direction towards a longitudinal centre axis (L1) of a flow distributor (1) arranged in the vessel (11).
Design of an Ethylene Oligomerization/Trimerization/Tetramerization Reactor
A process includes periodically or continuously introducing an olefin monomer and periodically or continuously introducing a catalyst system or catalyst system components into a reaction mixture within a reaction system, oligomerizing the olefin monomer within the reaction mixture to form an oligomer product, and periodically or continuously discharging a reaction system effluent comprising the oligomer product from the reaction system. The reaction system includes a total reaction mixture volume and a heat exchanged portion of the reaction system comprising a heat exchanged reaction mixture volume and a total heat exchanged surface area providing indirect contact between the reaction mixture and a heat exchange medium. A ratio of the total heat exchanged surface area to the total reaction mixture volume within the reaction system is in a range from 0.75 in.sup.−1 to 5 in.sup.−1, and an oligomer product discharge rate from the reaction system is between 1.0 (lb)(hr.sup.−1)(gal.sup.−1) to 6.0 (lb)(hr.sup.−1)(gal.sup.−1).
Continuous production of 2D inorganic compound platelets
Provided is a process for manufacturing 2D inorganic compound platelets, the process comprising (a) preparing a first stock containing a 3D layered inorganic compound material dispersed in a liquid medium, (h) injecting the first stock into a continuous reactor having a vortex flow, (c) operating the continuous reactor to form a reaction product suspension containing 2D inorganic compound platelets dispersed in the liquid medium, and (d) separating and recovering said 2D inorganic compound platelets from said product suspension. The product suspension may be directed to flow back to the continuous director for further processing for at least another pass through the reactor, prior to step (d). The continuous reactor is preferably a Couette-Taylor reactor.

Processing vacuum residuum and vacuum gas oil in ebullated bed reactor systems
A process for upgrading vacuum residuum and vacuum gas oil hydrocarbons is disclosed. The process may include: contacting a heavy distillate hydrocarbon fraction and hydrogen with a zeolite selective hydrocracking catalyst in a first ebullated bed hydrocracking reaction zone to convert at least a portion of the vacuum gas oil to lighter hydrocarbons. Contacting a residuum hydrocarbon fraction and hydrogen with a non-zeolite base metal hydroconversion catalyst in a second ebullated bed hydroconversion reaction zone may produce a vapor stream containing unconverted hydrogen, acid gases and volatilized hydrocarbons which may be fed along with the vacuum gas oil in the first ebullated bed hydrocracking zone.
