    摘要: A method for providing aerogels, and aerogels produced according to the method, is described. As one aspect, antiperspirant compounds that are in aerogel form, and antiperspirant and deodorant compositions including such salts, are described. The method involves contacting a solution containing material to be processed with a species selected to precipitate the material and selected so as to be miscible with the solvent system of the solution. After the material is precipitated, the material may be washed with the precipitating species until it is substantially free of solvent system. Then, the precipitating species containing the material precipitate is taken above its critical point, and the supercritical fluid is exhausted above its critical temperature. Alternately, a separate isolating species is introduced to displace the precipitating species, or the precipitating species/solvent system mixture. The isolating species then is taken above its critical point, and exhausted above its critical temperature. The invention provides for batch or continuous processes.

    摘要: A closed loop system for increasing yield, reducing post process pollution, reducing energy consumed during and after extraction of fuels or contaminants in formations and for sequestering of carbon dioxide C02 from various sources is converted to a critical fluid for use as a flushing and cooling medium. Electrical energy heats a hydrocarbon rich formation resulting in the extraction of hot fluids which are fed to heat exchangers, gas/liquid separator, and steam turbine whereby oil, electric power, carbon dioxide and methane are produced for reuse in the system or for external use. Further, a method for sequestering of carbon dioxide in a formation comprises the steps of injecting CO2 into the reservoir, flushing with cool pressurized CO2 for heat removal, infiltrating with ultra-fine low density suspended catalyst particles of dry sodium hydroxide in CO2, pumping water moistened CO2 into the reservoir to activate the catalysts, binding the CO2 with reacting materials and capping the reservoir.

    摘要: The extraction of hydrocarbon fuel products such as kerogen oil and gas from a body of fixed fossil fuels such as oil shale is accomplished by applying a combination of electrical energy and critical fluids with reactants and/or catalysts down a borehole to initiate a reaction of reactants in the critical fluids with kerogen in the oil shale thereby raising the temperatures to cause kerogen oil and gas products to be extracted as a vapor, liquid or dissolved in the critical fluids. The hydrocarbon fuel products of kerogen oil or shale oil and hydrocarbon gas are removed to the ground surface by a product return line. An RF generator provides electromagnetic energy, and the critical fluids include a combination of carbon dioxide (CO2), with reactants of nitrous oxide (N2O) or oxygen (O2).

    摘要: Disclosed are a fluid extractant, and a process and apparatus for using the extractant to separate an organic liquid from an aqueous mixture. The extractant comprises a first fluid solvent which is a gas in its near-critical or supercritical state and a cosolvent. A preferred first fluid solvent is near-critical liquid carbon dioxide. Preferred cosolvents are 2-ethyl hexanol for ethanol extraction, and hexanoic acid for acetic acid extraction. Organic compounds such as monohydric alcohols, monoacids, ketones, ethers, aldehydes and esters can be recovered from dilute aqueous solutions more economically than possible by prior art processes of distillation.

    摘要: A method of cleaning an industrial tank using electrical energy and critical fluid comprises the steps of transmitting electrical energy into an industrial tank to a first predetermined temperature, providing a critical fluid with a reactant or catalyst into the tank for diffusion into the contents of the tank at a predetermined pressure, transmitting electrical energy into the tank to heat the contents including the critical fluid to a second predetermined temperature to initiate reaction of a reactant in the critical fluid with a portion of the contents of the tank causing hydrocarbons and contaminants to be released for extraction as a vapor, liquid or dissolved in the critical fluid. A step of pressure cycling may be performed prior to a step of removing the contents of the tank including the hydrocarbons and contaminants. A further step includes separating the hydrocarbons, critical fluid, gases, and contaminants removed from the tank.

    摘要: An apparatus for the semi-automatic feeding of piglets up to 21 days old, comprises an open feeding trough which is supplied with liquid feed in predetermined quantities at predetermined intervals. The inlet to the feed trough is disposed substantially centrally along the length of the trough, in the vicinity of a raised area of the trough, so that the feed distributes itself to the end of the trough under gravity. The strong, dominant animal of the group automatically makes to feed from the trough vicinity of the feed inlet, and the sloping arrangement of the trough ensures that the smaller, weaker animals obtain an adequate supply of feed. The trough surface is smooth and essentially free from crevices, recesses and the like, so that it is essentially cleaned by the feeding piglets themselves.
