  • Patent number: 8748678
    Abstract: A synthetic fuel formula using a blend of High Density Synthetic (HDS) (e.g. Decalin and Tetralin), and Low Density Synthetic (LDS) (e.g. Synthetic Paraffinic Kerosene—SPK) is disclosed. This HDS and LDS blend has been shown to be useful as a jet, rocket and diesel fuel of standard density, and under low temperature conditions. The inventions described herein relate to 100% synthetic hydrocarbon fuels derived from various carbonaceous materials such as, but not limited to, biomass, municipal waste, natural gas, and coal. This 100% synthetic fuel can be universally used for both jet and diesel fuels. It meets Joint Battlefield Use Fuel of the Future (J-BUFF), or Single Battlefield Fuel (SBF) strategic requirements. The commercial advantage of the present invention is that it can be prepared from commercial available fuel stocks or co-processed using currently available chemical processes.

    Abstract: The invention provides methods of using positionally controlled molecular tools in an inert environment (such as ultra high vacuum) to fabricate complex atomically precise structures, including diamond, graphite, nanotubes, fullerenes, additional sets of the selfsame molecular tools, and others. Molecular tools have atomically precise tooltips which interact directly with a workpiece to add, remove, and modify specific atoms and groups of atoms, and have handles by which they can be held and positioned; tools can be recharged after use. Specific tooltips are brought into contact with and bond to specific feedstock molecules distributed on a presentation surface, and then transfer said feedstock molecules to specific atomic sites on a workpiece using mechanosynthetic chemical reactions. Specific sites on a workpiece can be made chemically reactive, facilitating the transfer of specific groups to them.

  • Patent number: 6784328
    Abstract: The invention relates to a method of selectively producing adamantanes in a production apparatus made of an inexpensive material, not having any negative influence on the natural environment. The method for producing adamantanes includes isomerizing a tricyclic saturated hydrocarbon having at least 10 carbon atoms in the presence of a metal-carrying solid acid catalyst, wherein an unsaturated bond-having compound is made to coexist along with the catalyst during the isomerization.

  • Patent number: 6512152
    Abstract: The present invention is drawn to a tetracyclododecene composition having a regulated cyclopentadiene trimer content, whereby addition polymerization with the aid of a Ziegler catalyst can be carried out while preventing gelation caused by a cross-linking reaction. A tetracyclododecene composition regulated with respect to the content of a specific ingredient having a molecular weight of 188 is disclosed, whereby polymers having high glass transition temperatures can be obtained through various polymerizations. Further, the present invention is drawn to a method for producing tetracyclododecene in the presence of an aliphatic solvent having a boiling point close to that of norbornene, which solvent is effective in inhibiting the recovered norbornene from solidifying.
