  • Publication number: 20090081292
    Abstract: An oil-containing solid in which liquid oil is contained in a large amount and from which oil seepage is slight; and a process for producing the same. The oil-containing solid is produced by impregnating a porous solid with a W/O emulsion. Further, use is made of the W/O emulsion having a water-soluble gellable substance incorporated in the water phase thereof. Consequently, the water-soluble gellable substance is converted to a gel in pores of the porous solid, thereby enhancing the liquid oil leakage preventing effect of the W/O emulsion.

  • Patent number: 5597947
    Abstract: This invention involves a process for improving the energy and ignitability of a metal slurry gel rocket fuel by the use of an energetic metal compound of higher energy than the parent metal. An energetic metal compound is added slowly to a liquid rocket fuel with appropriate stirring to form a suspension of the metallic compound in the liquid fuel. To this is added a small quantity of a gelling agent, such as silicon dioxide, with stirring, to form an energetic metal fuel gel. The energetic metal compound is prepared by using a high purity metal in the form of a wire. As an example, a sample of aluminum wire weighing 2.26 grams is supplied with an external source of high voltage and amperes, while the wire is in an environment of an inert gas (e.g., argon) under about 40 atmospheres pressure, to achieve electrical explosion of the wire. The product produced is a fine, gray, non-conductive powder in high yield. This powder contains aluminum and argon.

  • Patent number: 5514645
    Abstract: The present invention provides a method of treating a subterranean formation by rapidly viscosifying a normally liquid hydrocarbon. The method is accomplished by admixing (i) an alkyl orthophosphate acid ester and (ii) an alkali metal hydroxide present in an amount sufficient to at least partially neutralize said ester and (iii) a reaction product resulting from the reaction of a source of aluminum or ferric ions with a C.sub.8 -C.sub.18 surface active amine solubilized in the presence of an organic solvent such as a C.sub.2 -C.sub.4 monohydric alcohol with the normally liquid hydrocarbon. The mixture rapidly viscosifies to a level sufficient to transport proppant and then can be introduced into a subterranean formation to treat the formation in a desired manner.

    Abstract: This invention relates to the use, transport, storage, recovery and re-use of chemical compounds. In particular, the invention is directed to a method for reversibly transforming organic compounds into a phase more suitable for subsequent handling but from which the original organic compounds can be readily recovered. The invention is particularly suited for, but not limited to, the recovery and re-use of liquid hydrocarbons, either naturally occurring or synthetic, and/or their derivatives, and it is expected to be especially useful in the recovery of hydrocarbons from an oil spill.

  • Patent number: 5190675
    Abstract: A method of producing a gel of an organic liquid, using a metal phosphate ester in which all of the reagents are substantially free of water and pH-affecting substances. The gel is particularly useful in fracturing subterranean formations by entraining a solid particulate proppant therein and pumping the resultant mixture into the subterranean rock formation at sufficient pressure to fracture the formation. The organic liquid is preferably a hydrocarbon such as diesel or crude oil, and the metal phosphate ester is preferably an aluminum phosphate diester. The metal phosphate diester may be prepared by the reaction of a triester with P.sub.2 O.sub.5 to produce a polyphosphate, which is then reacted with an alcohol to produce a phosphate diester. The latter diester is then added to the organic liquid along with a non-aqueous source of aluminum, such as aluminum isopropoxide in diesel, to produce the metal phosphate diester.
