  • Patent number: 11097242
    Abstract: A wet gel granule of aerogel is prepared by the following steps: mixing step: mixing with an organic mixed solvent to form a mixed solution; hydrolysis step: adding an acid catalyst to the mixed solution for carrying out a hydrolysis reaction, and adding a dispersion solvent during the condensation reaction, and agitating to gel the mixed solution during agitation and produce multiple hydrophilic or hydrophobic wet gel granules of aerogel. The overall preparation speed can be shortened quickly and at the same time the hydrophilic or hydrophobic wet gel granules of aerogel wet glue particles are prepared to increase the production efficiency of the wet gel granules of aerogel.

  • Publication number: 20150068110
    Abstract: Techniques, systems and material are disclosed for transport of energy and/or materials. In one aspect, a method includes generating gaseous fuel (e.g., from biomass dissociation) at a first location of a low elevation. The gaseous fuel can be self-transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A liquid fuel can be generated at the second location of higher elevation by reacting the gaseous fuel with at least one of a carbon donor, a nitrogen donor, and an oxygen donor harvested from industrial waste. The liquid fuel can be delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy.

  • Patent number: 8815198
    Abstract: A method of purifying a gas stream formed from a process wherein a glyceride containing raw material is converted to hydrocarbon paraffins. The gas stream contains hydrogen or carbon dioxide as a major component and at least one sulphurous component selected from sulphide compounds as an impurity. The gas is contacted with an acidic aqueous wash solution of transition metal ions capable of binding to sulphide ions. A significant portion of the sulphide compounds contained in the gas are bound into practically insoluble transition metal sulphide compounds to remove sulphide compounds from the gas to produce a purified gas. The obtained purified gas is recovered. The method efficiently lowers sulphide concentrations to ppm or sub-ppm level and it can be implemented on an industrial scale with low investment costs. The metal can be recovered.

  • Publication number: 20110239962
    Abstract: An alternative or supplement to combustion within an engine is decomposition of nitrous oxide into two parts nitrogen, one part oxygen. This decomposition releases thermal energy that may be captured and converted to useful work. Traditional combustion engines are limited to oxidizer/fuel ratio ratios near the proportional mixture of fuel and oxidizer that achieves complete combustion of the fuel. The presently disclosed technology increases the oxidizer/fuel ratio above that of all traditional combustion engines and still achieves useable power output primarily through decomposition of nitrous oxide. Decomposition of nitrous oxide into nitrogen and oxygen in an engine outputs two parts nitrogen and one part oxygen, which is roughly equivalent to oxygen rich atmospheric air. Output of carbon dioxide and other undesirable chemical compounds is avoided when compared to combustion of a carbon-hydrogen fuel and an oxidizer containing oxygen.
