Abstract:
The present invention relates to a chemical feeder that includes a support plate that is positioned within the housing chamber of the chemical feeder, in which one or more extensions extend upward from an upper surface of the base plate of the support plate. The extensions can, with some embodiments, be in the form of peg extensions, arcuate extensions that can together define an impeller pattern, or a spiral extension. A distributor head having a plurality of distributor head apertures and at least one dome hole extends up through a support plate aperture in the base plate of the support plate, and distributes liquid horizontally and vertically relative to the base plate. The horizontally and vertically distributed liquid contacts a solid chemical material that is supported above the support plate, so as to form a treated liquid that includes dissolved chemical material.
Abstract:
An apparatus for manufacturing a carbon nanostructure and a method for manufacturing a carbon nanostructure that can achieve an increase in length and shape stabilization of the carbon nanostructure can be obtained. A manufacturing apparatus for a carbon nanostructure includes a catalyst member on which a carbon nanostructure is grown, a source gas supply unit and a source gas supply pipe, a coil, and a heater. The source gas supply unit and the source gas supply pipe supply the catalyst member with carbon for forming the carbon nanotube. The coil applies a gradient magnetic field (e.g., a cusped magnetic field indicated by magnetic flux line whose magnetic field strength gradually increases from one surface of the catalyst member to the other surface opposite to the one surface. The heater heats the catalyst member.
Abstract:
An apparatus and method for adding an alkali metal promoter into steam and contacting the solution with a dehydrogenation catalyst during a dehydrogenation reaction is disclosed. The apparatus has a first conduit capable of transporting an alkali metal salt solution and a second conduit in fluid communication with the first conduit, the second conduit capable of transporting steam so that the alkali metal salt is dissipated into the steam prior to entry into a dehydrogenation reaction zone.
Abstract:
The invention provides a process for producing carbon nanotubes which includes supplying a continuous fluidized feed of a catalyst and at least one hydrocarbon to a reactor operating under conditions suitable to produce carbon nanotubes. The fluid is made to flow though the reactor with a swirling motion which ensures that the internal surfaces of the reactor are cleaned of deposits.

Methods and systems for on-site generation of peracid chemistry, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions, are disclosed. In particular, an adjustable biocide formulator or generator system is designed for on-site generation of peroxycarboxylic acids and peroxycarboxylic acid forming compositions from sugar esters. Methods of using the in situ generated peroxycarboxylic acids and peroxycarboxylic acid forming compositions are also disclosed.
Abstract:
A method for the delivery of a catalyst to a polymerization reactor is disclosed, comprising: contacting a catalyst with a carrier fluid comprising an inert hydrocarbon in gaseous form, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.; and flowing the carrier fluid to the polymerization reactor such that the carrier fluid transports the catalyst to the polymerization reactor. A catalyst delivery system is disclosed, comprising: a catalyst vessel for containing a catalyst; a catalyst injection line for delivering the catalyst to a polymerization reactor, the catalyst injection line being in fluid communication with the catalyst vessel and the polymerization reactor; and a carrier fluid line in fluid communication with the catalyst injection line for delivering a carrier fluid comprising an inert hydrocarbon to the catalyst injection line, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.
Abstract:
In certain embodiments, a feed injector system includes an inner channel configured to convey at least one of a solid fuel feed or a liquid reactant or moderator to a reaction zone. 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:
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.
