The invention relates to equalizing and distributing vapor more evenly across the interior space of a reactor vessel utilizing an equalizing section and distributor section at the inlet end and a fixed valve tray at the bottom of the reactor to equalize and distribute the flow.

The invention relates to distributing reactants more evenly across the interior space of a reactor vessel utilizing a distributor at the inlet end that initially directs the flow of reactants through a series of circumferential nozzles. The nozzles are physical spaced such that the first nozzle provides the reactants into the vessel to spread radially and broadly outwardly into the vessel and each successive circumferential nozzle to deliver reactants in a less broadly distribution or dispersion where the interior space is filled with reactants without broadly diverse velocities that may create hot spots within the catalyst bed. The invention further includes a catalyst support tray having through holes that are sized and spaced to limit higher velocity regions within the catalyst bed and cause a more even distribution of the flow and thereby reduce hot spots within the catalyst bed.

The invention relates to equalizing and distributing reactants more evenly across the interior space of a reactor vessel utilizing a combination equalizer and distributor at the inlet end that initially impedes with uneven flow rates of vapor and then directs the flow of vapor through a series of circumferential nozzles. The nozzles are physical spaced such that the first nozzle provides the reactants into the vessel to spread radially and broadly outwardly into the vessel and each successive circumferential nozzle to deliver reactants in a less broadly distribution or dispersion where the interior space is filled with reactants without broadly diverse velocities that may create hot spots within the catalyst bed.

A method of producing hydrogen in a plant for hydrogen production during combustion of a mixture of hydrocarbon feedstock with an oxidizer with an oxidant excess ratio of less than 1. The method is characterized in that the combustion process is carried out at a temperature of less than 1400 K inside several cavities, completely or partially formed by a material permeable to a mixture of hydrocarbon feedstock with an oxidant.

The invention relates to a process for producing superabsorbent polymer particles, comprising polymerization of a monomer solution, wherein the monomer solution comprises partly neutralized acrylic acid formed by continuous mixing of acrylic acid and an aqueous solution of a base, the apparatus for preparing the partly neutralized acrylic acid comprises a vessel (B), and the vessel (B) has a cylindrical shape and a torispherical bottom.

A jet impingement reactor having a housing made of a polymeric material, including at least two housing pieces that are affixed to one another. The housing encloses a substantially spherical reaction chamber having at least two fluid inlets provided by nozzles and a fluid outlet. Further provided are methods for making the reactor based on injection molding, as well as the use of the reactor for the aseptic manufacture of a sterile liquid pharmaceutical compositions, in particular compositions including nanoparticles such as lipid nanoparticles.

A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.
