Abstract:
A method of improving the combustion of a fuel by adding a catalyst or combustion enhancer at an extremely low concentration, preferably in the range of 1 part catalyst per 200 million parts fuel to 1 part catalyst per 6 trillion parts fuel. The catalyst or combustion enhancer may be selected from a wide range of soluble compounds. The method may comprise the steps of an initial mixing of the catalyst or enhancer with a suitable solvent and then subsequent dilution steps using solvents or fuel. Suitable solvents include water, MTBE, methylketone, methyisobutylketone, butanol, isopropyl alcohol and other hydrophilic/oleophilic compounds.
Abstract:
Methods for producing alcohols and oligomers contemporaneously from a hydrocarbon feed containing mixed butenes using an acid based catalyst are provided. Additionally, methods for producing fuel compositions having alcohols and oligomers prepared from mixed olefins are also provided as embodiments of the present invention. In certain embodiments, the catalyst can include a dual phase catalyst system that includes a water soluble acid catalyst and a solid acid catalyst.
Abstract:
A method of producing a mixed higher alcohol blend is disclosed which may be self contained both composition-wise with regard to the specific alcohols as well as energy-wise. In one embodiment, the energy created during an exothermic Fischer-Tropsch reaction is utilized to drive downstream distillation column reboilers in a cascade mechanism, thereby providing a low energy process. In one embodiment, an extraction process is performed utilizing a suitable solvent and the co-solvent capabilities of the C4+ higher alcohols already present in the aqueous alcohol stream provided to the extraction column.
