    摘要: A method of making hydrocarbons from polyalcohols, such as carbohydrates. The polyalcohols and carbohydrates may be provided from biomass, including paper, cardboard or urban generated paper product waste; wood and wood products, including forest slash and deadfall; agricultural waste; and the like. The polyalcohols and carbohydrates are combined with hydroiodic acid in aqueous solution to form the hydrocarbon and elemental iodine. Hydroiodic acid is then electrochemically regenerated by reducing the elemental iodine in a parallel reaction. A method of electrochemically generating hydroiodic acid from elemental iodine in aqueous solution is also described.

    摘要: Water purification using organic salts. Feed water is mixed with at least one organic salt at a temperature sufficiently low to form organic salt hydrate crystals and brine. The crystals are separated from the brine, rinsed, and melted to form an aqueous solution of organic salt. Some of the water is removed from the aqueous organic salt solution. The purified water is collected, and the remaining more concentrated aqueous organic salt solution is reused.

    摘要: Methods are provided for the selective removal of CO2 from a multicomponent gaseous stream to provide a CO2 depleted gaseous stream having at least a reduction, e.g. 30 to 90%, in the concentration of CO2 relative to the untreated multicomponent gaseous stream. In practicing the subject methods, the multicomponent gaseous stream is contacted with an aqueous fluid, e.g. CO2 nucleated water, under conditions of selective CO2 clathrate formation to produce a CO2 clathrate slurry and CO2 depleted gaseous stream. A feature of the subject invention is that a CO2 hydrate promoter is employed, where the CO2 hydrate promoter is included in the multicomponent gaseous stream and/or the aqueous fluid. The CO2 hydrate promoter serves to reduce the minimum CO2 partial pressure required for hydrate formation as compared to a control. The subject methods find use in a variety of applications where it is desired to selectively remove CO2 from a multicomponent gaseous stream.
