  • Publication number: 20040137289
    Abstract: A method of generating a nuclear reaction from a gas stream containing water which involves heating a gas stream at a rapid rate sufficient to dissociate the water into hydrogen and oxygen and to transform hydrogen ions into protons which produce nuclear reactions, including nuclear fusion. Once the reaction state is reached, no additional heat needs to be inputted into the reaction system. Electrons that are freed from chemical species during the resulting nuclear reaction can be collected and used to produce electricity. In addition, hydrogen that is produced during the resulting nuclear reaction can be collected and used as a fuel in internal combustion engines, engine driven machine or piece of equipment.

  • Patent number: 6287534
    Abstract: A method for accelerating the rate of chemical reactions is disclosed consisting of subjecting a gas stream from a flue stream, industrial source, or utility boiler to a high time rate of change of temperature increase so as to convert certain polyatomic components of the gas stream to desired product, separating these oxidized polyatomic molecules from the gas stream, and subjecting the remaining polyatomic molecules to a high time rate of change of temperature decrease to convert the second type of polyatomic molecule to desired product.

  • Patent number: 5753201
    Abstract: A method for manufacturing sulfuric acid from a gas containing sulfur oxides, water and oxygen comprising subjecting the sulfur oxides rich gas to either an adiabatic compressor or a flame impinger to rapidly increase the temperature so that the sulfur dioxide in the gas is converted into sulfur trioxide and cooling the sulfur trioxide rich gas to produce sulfuric acid.

  • Patent number: 5084258
    Abstract: Sulfur dioxide (SO.sub.2) can be oxidized to rapidly sulfur trioxide (SO.sub.3) in a high temperature environment. It has been found that the SO.sub.2 oxidation rate can be impeded by a high rate of temperature reduction in a dynamic condition such as in a boiler and the ductwork of a power plant and an industrial plant. The mechanism of the reaction kinetics has been developed. With the understanding of the mechanism, the methods for oxidation of SO.sub.2 to form SO.sub.3 have been developed. The SO.sub.3 rich flue gas is treated with lime (CaO) in a fluidized lime reactor wherein SO.sub.3 reacts with CaO to form CaSO.sub.4 coating on the surface of CaO. The high heat generated from the SO.sub.3 /CaO reaction causes the remaining SO.sub.2 to convert in the reactor to SO.sub.3 which in turn reacts with CaO to form more CaSO.sub.4. Nitrogen oxides can also be removed from flue gas by converting nitric oxide (NO) to nitrogen dioxide (NO.sub.

  • Patent number: 4975257
    Abstract: The improved flue gas desulfurization process is effective for removing sulfur dioxide in the flue gas with a lime-bearing material in a fluidized lime reactor (50, 110, 164, 426). The effectiveness of the process is due primarily to the presence of sulfur trioxide in the gas, the sulfur trioxide being generated in a catalytic converter (40, 156, 418) and a bypass circuit (20, 408) transmitting a portion of the flue gas past the catalytic converter (40, 418). Sulfur trioxide may also be directly injected by duct injection in order to enhance the removal of sulfur dioxide from flue gas in the fluidized lime reactor (110, 164). In the initial phase, the duct injected sulfur trioxide efficiently raises the temperature of the lime-bearing particles (7) from the exothermic reaction with lime, resulting in the establishment of the steep temperature and sulfur oxides gradients which induce an autogeneous conversion of sulfur dioxide to sulfur trioxide.

  • Patent number: 4756893
    Abstract: Gases containing high sulphur dioxide concentrations are used for energy production. The steps involve the conversion of sulphur dioxide to sulphur trioxide in a catalytic converter (40, 360, 570), the reaction of sulphur trioxide with lime and/or limestone in a fluidized reactor (60, 410, 580), and removal of heat from the chemical reactions for utilization in the production of superheated steam. The superheated steam that is produced can be used for the generation of electricity, for operating mechanical devices, space heating, lime production, construction materials curing, and heat exchange processes.

  • Patent number: 4600570
    Abstract: A process for effecting the continuous desulphurization of stack gases includes a double loop computerized system (10) for continuously effecting the desulphurization. The stack gases are passed through heat exchangers (14, 15) to raise the temperature to approximately 700.degree. F., the first heat exchanger (14) receiving hot desulphurized exit gas from a reactor (27) and the second heat exchanger (15) receiving preheated SO.sub.3 rich flue gases from a catalytic converter (17). The stack gases heated to 700.degree. F. are passed through a preheater burner (16) to increase the temperature to about 850.degree. F. and then transmitted through the catalytic converter (17) to convert most of the sulphur dioxide to sulphur trioxide. The sulphur trioxide rich flue gas is recirculated through the second heat exchanger (15) in order to cool the flue gas, and then fed to the reactor (27) which receives either calcium oxide, calcium carbonate, or both in order to effect SO.sub.x removal.

  • Patent number: 4470921
    Abstract: A solid pollution-treatment product consisting of a core material of lime, quicklime or hydrated lime. The core is surrounded by a cracked shell formed of either calcium sulfate or calcium carbonate, such materials being referred to in this and prior applications of inventor by the coined terms "Linfans" and "Linveins", respectively.The described particulate material is particularly reactive to sulfur oxide bearing gases. Reactivity of such core material is even further enhanced by increasing its porosity through hydration and used in either the hydrated form or a selectively, partially or wholly dehydrated form before exposure to the sulfur oxide pollutants intended to be removed from flue gas or the like.

  • Patent number: 4054463
    Abstract: A cementitious product is produced from a combination of two groups of materials: the first group consisting of lime or Portland cement or Linfan (which is defined as a thermally cracked shell of calcium sulfate surrounding a core of lime) or Linvein (a lime particle coated with cracked calcium carbonate); and a second material consisting of thermally cracked fly ash which is cracked by thermally quenching such finally divided particulate material from an elevated temperature at least above 300.degree. C and preferably higher than 450.degree. C to ambient or below ambient temperatures.The two materials are blended together. They are mixed with water, placed in a form, and then allowed to cure. Filler materials can also be used in the form of sand, gravel, and other aggregates, depending upon the strength and compositional characteristics desired in the final product.
