  • Patent number: 11338262
    Abstract: In a catalytic reaction, after a reaction product leaves a catalyst bed, an inert substance with a low temperature is sprayed, and through heat absorption and vaporization processes of the inert substance, the temperature of the reaction product drops rapidly when staying in a catalyst cushion layer at a discharge end of a fixed bed reactor, or in a space formed by the catalyst cushion layer at the discharge end of the fixed bed reactor and a reactor head, or in a space formed by a tube plate at the discharge end of the fixed bed reactor and the reactor head. The residence time of the reaction product is shortened due to the entrance of the inert substance in a gaseous state.

  • Patent number: 11325097
    Abstract: A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

  • Patent number: 11318437
    Abstract: 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.

  • Patent number: 11291971
    Abstract: A planar flow reactor includes a straight planar process channel, a flow generator, and a plurality of static mixing elements disposed within the process channel. The flow generator is configured to generate a pulsatile flow within the process channel, and the static mixing elements are configured to locally split and recombine the flow. The straight planar process channel enables the generation of a flow pattern that is largely independent of the width of the process channel, meaning that the throughput may be increased by increasing the width without significantly affecting the residence time distribution or the flow behavior. Furthermore, by creating a pulsatile flow within the process channel, turbulence and/or chaotic fluid flows may be generated even at low net flow rates, i.e. low net Reynolds numbers.
