  • Publication number: 20100282644
    Abstract: Systems and methods are provided for low emission (in-situ) heavy oil production, using a compound heat medium, comprising products of combustion of a fuel mixture with an oxidant and a moderator, mixed with steam generated from direct contact of hot combustion products with water, under pressure. The compound heat medium, comprising mainly CO2 and steam, is injected at pressure into a hydrocarbon reservoir, where steam condenses out of the compound heat medium releasing heat to the reservoir. The condensate is produced with the hydrocarbon as a hydrocarbon/water mixture or emulsion. Non-condensable gases, primarily CO2, from the compound heat medium may remains in the reservoir through void replacement, leakage to adjacent geological strata. Beneficially, any CO2 produced is recovered at pressure, for use in other processes, or for disposal by sequestration. Produced water is recovered and recycled as a moderator and steam generating medium.

  • Patent number: 7547385
    Abstract: A method for producing a supercritical cryogenic fuel (SCCF) includes dissolving a hydrogen gas in fuel value proportions into a supercritical hydrocarbon fluid. The method is performed by placing a hydrogen gas and a hydrocarbon fluid at a pressure greater than the critical pressure of the hydrocarbon, placing the hydrogen gas and the hydrocarbon fluid at a temperature below or approximately equal to the critical temperature of the hydrocarbon forming the supercritical hydrocarbon fluid, and then mixing to dissolve the hydrogen gas into the supercritical hydrocarbon fluid. A system for performing the method includes a vortex mixer configured to turbulently mix the hydrogen gas and the supercritical hydrocarbon fluid. The supercritical cryogenic fuel (SCCF) produced by the method and the system includes the supercritical hydrocarbon fluid with a selected mole fraction of the hydrogen gas dissolved therein.

  • Patent number: 7541502
    Abstract: Disclosed are fuel compositions for internal combustion engines comprising as a predominant component organic distillates which exhibit suitable physical properties, and a low-sulfur fraction of an alkylated petroleum feedstock which, for example, consisted of material boiling between about 60° C. and about 345° C. More particularly, compositions of the invention comprise low-boiling, low-sulfur, blending components, advantageously obtained by a process for converting sulfur-containing organic compounds which are unwanted impurities, to higher boiling products by alkylation and removing the higher boiling products by fractional distillation. Products can be used directly as transportation fuels and/or blending components to provide fuels which are more friendly to the environment.
