Abstract:
A catalyst structure 1 used for hydrogenation reaction or dehydrogenation reaction is characterized by the inclusion of a first coiled catalytic wire body 4 formed by coiling a catalytic wire in which a catalytic material is supported on the surface of a metallic core material, and a second catalytic member 5 disposed on the inner surface side and/or outer surface side of the coiled catalytic wire body 4.
Abstract:
An apparatus for mass transfer of a gas into a liquid, including a tank that defines a chamber for receiving the gas, and at least one surface provided within the chamber. Each surface has an inner region, an outer region and an edge adjacent the outer region. Each surface is configured to receive the liquid at the inner region and rotate such that the liquid flows on the surface from the inner region to the outer region, and, upon reaching the edge of the surface, separates to form liquid particles that move outwardly through the gas in the chamber. The liquid particles are sized so that the gas is absorbed by the liquid particles to produce a mixed liquid saturated with the gas during a brief flight time of the liquid particles through the chamber.
Abstract:
A reaction apparatus which is used for conducting a gas-liquid chemical reaction in a state that a liquid is in a continuous phase, wherein its reactor has therein a shear type stirring impeller for dispersing a raw reaction gas or a carrier gas and a film-formed catalyst, which apparatus is capable of producing a target reaction product; and a process for producing a tertiary amine in such reaction apparatus.
Abstract:
A reformer module (10) comprises a hollow support member (12) having at least one passage (14) extending longitudinally therethrough. The hollow support member (14) has an external surface (20), a barrier layer (22) arranged on at least a portion of the external surface (20) of the hollow support member (12), a catalyst layer (24) arranged on the barrier layer (22) and a sealing layer (26) arranged on the catalyst layer (24) and the external surface (20) of the hollow support member (12) other than the at least a portion of the external surface of the hollow support member (12). By providing the barrier layer (22) and the catalyst layer (24) on the exterior surface (20) of the hollow support member (12), the distribution of the barrier layer (22) and/or the catalyst layer (24) may be more precisely controlled and thus a non-uniform distribution of barrier layer (22) and/or catalyst layer (24) may be achieved.
Abstract:
A tube reactor having a substantially tubular body portion including a conical section, an entry port, an opposing exit port, and an axis extending between the ports through the body portion. The tubular body portion being rotatable about the axis. At least one reactant can be fed into the tubular body portion and directed toward the conical section. An inner surface of the tubular body portion receives the reactants from the conical section, and processes the reactants. An insert may be positioned within the tubular body portion to further process the reactants along the inner surface. A rotating reservoir having a damper can be coupled to the rotating tubular body portion. The damper receives the processed reactants from the inner surface of the tubular body portion, and guides the processed reactants into the rotating reservoir to minimize turbulence. The rotating reservoir then separates the processed reactants by density.
Abstract:
Electrochemical cells (10), such as fuel cells (12) and fuel reformers (14), with rotating elements or electrodes (34, 24) that generate Taylor Vortex Flows (28, 50) and Circular Couette Flows (58) in fluids such as electrolytes and fuels are disclosed.
Abstract:
A method and apparatus for fluid-liquid reactions including gas-liquid and liquid-liquid reactions. The method and apparatus is suitable for mixing a fluid phase species and a liquid phase species to facilitate chemical reaction between said phases. The apparatus comprises a reactor vessel with a plurality of orificed plates and flow control means which initiates and maintains uniform mixing and efficient dispersion of a fluid-liquid mixture within the reactor vessel.

Abstract:
A method of use for a high shear device incorporated into a process or system for the production of acetaldehyde from ethylene as a reactor device is shown to be capable of decreasing mass transfer limitations, by forming a feed stream emulsion, and thereby enhancing the acetaldehyde production process in the system.
Abstract:
Biogases such as natural gas and other gases capable of being biologically derived by digestion of organic matter are converted to a clean-burning hydrocarbon liquid fuel in a continuous process wherein a biogas is fed to a reaction vessel where the biogas contacts a liquid petroleum fraction and a transition metal catalyst immersed in the liquid, vaporized product gas is drawn from a vapor space above the liquid level, condensed, and fed to a product vessel where condensate is separated from uncondensed gas and drawn off as the liquid product fuel as uncondensed gas is recycled to the reaction vessel.
