Abstract: System and methods for producing synthesis gas are provided. The system includes a reactor and a steam generation system designed to provide precise control of the rate of steam generation to mix steam with fuel gas to produce humidified fuel gas, which is then fed into a combustion chamber of the reactor. The molar ratio of hydrogen to carbon monoxide in the synthesis gas output from the reactor may be accurately controlled by adjusting the humidity of the fuel gas input into the combustion chamber.

Abstract: A reaction assembly has an elongate vessel defining a reaction chamber. Planar supports within the reaction chamber have surfaces for supporting a solid catalyst. The planar supports are mounted transversely to an elongate axis of the vessel, forming a series of spaced-apart barriers. A conduit introduces gas through openings between successive barriers such that gas flow through the conduit causes gas to flow along the support surfaces. With selection of an appropriate metal nanoparticle catalyst that may be seeded on the support surfaces. the reaction assembly may be used to produce carbon nanofibers from carbon monoxide and hydrogen, wherein the nanofibers may be subsequently removed via injection of a fluid.

Abstract: A solar reactor useful in reaction processes, more particularly, useful in endothermic reaction processes, such as a catalyzed process or an adsorption-desorption process. The reactor comprises a reaction pathway defined by an exterior wall and an interior wall, the exterior wall comprising a solar radiation receiver capable of converting solar radiation into heat and transmitting the heat to the reaction pathway. The reaction pathway has disposed therein, in alternating fashion, a plurality of reactive elements comprised of a catalyst or a sorbent and a plurality of heat transfer elements.

Abstract: A reactor system including a plurality of catalytic modules connected end-to-end, forming a passage for reactants to pass through individually heated catalytic heating elements, thereby producing products. Each catalytic module has an insulating housing containing a catalytic heating element and configured to pass reactants over the catalytic heating element. A conductor in the module applies electricity to the catalytic heating element, which operates as a combined catalytic material and heating element.

Abstract: A helical photoreactor includes a lamp module and a tube coil, which has a plurality of tube windings between an input section and an output section. The tube coil is arranged around the lamp module. The helical photoreactor has a carrier device, which carries the tube coil, and a protective housing, which surrounds a receiving space, in which the carrier device with the tube coil and the lamp module are arranged. The carrier device provides a predetermined positioning of the tube coil with respect to the lamp module and the protective housing. An elongated guide element, on which an engagement element is arranged so as to be capable of being guided in a longitudinally movable manner and so as to be capable of being positioned. The elongated guide element specifies the positioning of the carrier device with the tube coil by the engagement element guided on the elongated guide element.

Abstract: A process and system for upgrading an organic feedstock including providing an organic feedstock and water mixture, feeding the mixture into a high-rate, hydrothermal reactor, wherein the mixture is rapidly heated, subjected to heat, pressure, and turbulent flow, maintaining the heat and pressure of the mixture for a residence time of less than three minutes to cause the organic components of the mixture to undergo conversion reactions resulting in increased yields of distillate fuels, higher-quality kerosene and diesel fuels, and the formation of high octane naphtha compounds. Hydrocarbon products are cooled at a rate sufficient to inhibit additional reaction and recover of process heat, and depressurizing the hydrocarbon products, and separating the hydrocarbon products for further processing. The process and system can include devices to convert olefinic hydrocarbons into paraffinic hydrocarbons and convert olefinic byproduct gas to additional high-octane naphtha and/or heavier hydrocarbons by one of hydrogenation, alkylation, or oligomerization.
