    Abstract: A system and method is provided which includes using a liquid treatment apparatus, which is equipped with cyclonettes, for example, to subject a liquid medium processing stream in an alcohol production process to hydraulic cavitation, i.e., to shear under vacuum, at one or more locations. The liquid treatment apparatus, in one embodiment, is directed to the formation of a central axial jet and a vacuum chamber that can be sealed by the exiting jet. Cavitation is generated by directing a high velocity jet of liquid medium processing stream through a volume of vapor under a vacuum created in the chamber through which the jet travels. This can reduce the production cost of alcohol, such as ethanol, by improving alcohol yield per bushel, among other benefits. In one embodiment, the alcohol production process is a dry grind process, a modified dry grind process, or a wet mill process.

    Abstract: A method to prepare new or unexpected polymorphs of materials which have not been observed, or to obtain a known polymorph under different conditions than those in which it is usually made, by using a laser to cause nucleation and crystal growth to occur in a supersaturated solution in such a way as to obtain a crystal structure which would not normally appear without the use of the laser.

  • Patent number: 6328854
    Abstract: A porous tube is positioned coaxially around and in axial alignment with a tubular lamp forming an annulus therebetween. Methane is directed through the porous tube and forms submicron size bubbles in a liquid flowing through the annulus. Energy from the tubular lamp generates hydroxyl radicals in the liquid which combine with the methane to form methanol. Photocatalytic material may be provided in the annulus either in the form of a layer of photocatalytic material formed on the interior surface of the porous tube or in the form of particles of photocatalytic material circulating through the annulus with the flowing liquid. A heat transfer apparatus may be provided in the annulus for removing heat generated by operation of the lamp.

  • Patent number: 6267849
    Abstract: A method for converting methane hydrates to methanol, as well as hydrogen, through exposure to light. The process includes conversion of methane hydrates by light where a radical initiator has been added, and may be modified to include the conversion of methane hydrates with light where a photocatalyst doped by a suitable metal and an electron transfer agent to produce methanol and hydrogen. The present invention operates at temperatures below 0° C., and allows for the direct conversion of methane contained within the hydrate in situ.

  • Patent number: 6214176
    Abstract: In a method of and apparatus for manufacturing methanol and higher alcohols from natural gas a catalytic area is formed on the exterior of a gas permeable partition. Natural gas is maintained on the interior of the gas permeable partition at predetermined pressure. Relative movement between the gas permeable partition and the water forms sub-micron sized bubbles of natural gas. Electromagnetic radiation is directed onto the catalytic surface to form hydroxyl radicals from the water. Methyl, ethyl, and propyl ions from the natural gas combine with the hydroxyl ions to form methanol, ethanol, and propanol.
