Abstract:
Provided is a gas isolation valve which separates reactive materials, principally gases, contained in a high temperature reactor from the surrounding atmosphere. The valve is of modular construction with each module having a gas providing section and a gas removal section. Any number of modules can be provided in series. A central chamber, open at each end gives unimpeded access to the high temperature reactor. It is through the central chamber that the product of the reactor is removed and harvested. In the case of Ilas invention the product is carbon nanotubes.

A first oxidizer channel extends around the inner channel, wherein the first oxidizer channel is configured to convey a first oxidizer stream to the reaction zone. A second oxidizer channel extends around the first oxidizer channel, wherein the second oxidizer channel is configured to convey a second oxidizer stream to the reaction zone. Additionally, a third channel extends around the inner channel and the first and second oxidizer channels, wherein the third channel is configured to convey at least one of the solid fuel feed or the liquid reactant or moderator to the reaction zone.
Abstract:
Reactors for carrying out a chemical reaction, as well as related components, systems and methods are provided. In accordance with one embodiment, a reactor is provided that includes a furnace and a crucible positioned for heating by the furnace. The crucible may contain a molten salt bath. A downtube is disposed at least partially within the interior crucible along an axis. The downtube includes a conduit having a first end in communication with a carbon source and an outlet at a second end of the conduit for introducing the carbon material into the crucible. At least one opening is formed in the conduit between the first end and the second end to enable circulation of reaction components contained within the crucible through the conduit. An oxidizing material may be introduced through a bottom portion of the crucible in the form of gas bubbles to react with the other materials.
Abstract:
A process is described for converting and utilizing oxygen-containing polymers to form hydrogen and alkali metal carbonates, in which the polymers are brought into intimate contact with a melt mixture of alkali metal hydroxide and alkali metal carbonate to form hydrogen and alkali metal carbonate, and the alkali metal carbonate formed is removed from the reaction mixture during the reaction and alkali metal hydroxide is optionally metered in. The reaction is preferably carried out under conditions which lie on a point on the Liquidus line of the system. It is possible in accordance with the invention to process natural or synthetic polymers, for example polyester, polyether, wood, etc. It is particularly suitable for processing fiber-reinforced composite materials. Also described is an apparatus for performing the process according to the invention.
Abstract:
A fluid-processing device is provided for bringing two kinds of fluids into contact to mix or react with each other. The device comprises a first supply path connected to a first feed inlet for feeding a first fluid for supplying the first fluid, and plural second supply paths connected to a second feed inlet for feeding a second fluid for supplying the second fluid; the second supply paths being arranged along supply direction of the first fluid, the second supply paths being surrounded by the first fluid, the second fluid discharged from fluid outlets of the second supply paths being brought into contact with the first fluid in the first supply path.
Abstract:
A method is disclosed for producing energy from the controlled reaction of an alkali metal with water. The method comprises forcing a liquefied alkali metal through a filter that separates the liquid alkali metal into alkali metal droplets. The alkali metal droplets comprise small enough particles that the alkali metal droplets completely react in water to produce heat, steam, an alkaline hydroxide and hydrogen gas before the alkali metal droplets reach the surface of the water. The filter separates the alkali metal droplets at a sufficient distance to avoid recombining of the alkali metal droplets. The alkaline hydroxide is reduced to an alkali metal and water which can be reused in the system.
Abstract:
A reactor system operable to facilitate a chemical reaction in a reaction medium flowing therethrough. The reactor system includes a heat exchanger for heating the reaction medium and a disengagement vessel for disengaging vapor from the heated reaction medium.
Abstract:
The distributor serves for a pairwise delivery of two liquids to a plurality of infeed sites in a reactor or in a column with a density of at least 50 sites per m2. The distributor has a pair of main passages that supply pairs of secondary passages with different liquid. Each pair of secondary passages is formed by a pair of upstanding side parts and an upstanding partition wall. Each side part has a base extending from a lower edge to the partition wall to define a secondary passage therewith for receiving liquid from a respective one of the main passages, and each base has a plurality of outlet apertures for the outflow of liquid from the respective secondary passage.
Abstract:
A method and apparatus for the conversion of aromatic alkyls to aromatic carboxylic acids in a reactor are provided, wherein the location of the feeding of the reaction mixture into the reactor significantly increases the conversion efficiency of the precursor materials.
Abstract:
A process for polymerizing or oligomerising a hydrocarbon includes feeding at a low level a liquid hydrocarbon reactant into a bulk liquid phase comprising polymeric or oligomeric product admixed with a catalyst. The liquid hydrocarbon reactant is allowed to vapourise to form bubbles rising through the bulk liquid phase and to polymerise or oligomerise to form the polymeric or oligomeric product, with the rising bubbles creating turbulence in the bulk liquid phase, thereby mixing the bulk liquid phase. Gaseous components comprising any unreacted vapourised hydrocarbon reactant and any gaseous product that may have formed are withdrawn from a head space above the bulk liquid phase. Liquid phase from the bulk liquid phase is withdrawn to maintain the bulk liquid phase at a desired level.
