Patents by Inventor Robert E. Tang

Robert E. Tang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9254472
    Abstract: A novel process and apparatus is disclosed for performing chemical reactions. Highly compressed gaseous streams such as H2, CO, CO2, H2O, O2, or CH4 are raised to Mach speeds to form supersonic jets incorporating shockwaves. Two or more such jets are physically collided together to form a localized reaction zone where the energy from the shockwaves causes endothermic reactions wherein the chemical bonds of the reactant gases are broken. Between and among reactants molecular surface interaction and molecular surface chemistry take place. In the ensuing exothermic reactions a desired new chemical product is formed and this product is locked into a lower state of enthalpy (state of energy of formation) through adiabatic cooling by means of a free jet expansion.
    Type: Grant

  • Patent number: 7842264
    Abstract: A multiple stage apparatus and process using aerodynamic reactors and aero-coalescers in sequence for the selective capture and removal of purified carbon dioxide gas, the sequential capture and removal of mercury, metal and particulate aerosols by a recycling chemical generation-regeneration system using alkali metal chloride solution following multiple oxidations of mercury vapor, and nitric oxide in sequence, selective capture and removal of sulfur dioxide and nitrogen dioxide by two stage absorption by a recycling chemical generation-regeneration system using alkali metal hydroxide-carbonate-bicarbonate solution together with sequential oxidation to alkali metal sulfate and alkali metal nitrate compounds through evaporation and crystallization. Carbon dioxide capture and recovery is achieved in sequence by selective thermal decarbonation from an alkaline liquid followed by recovery as a purified gas stream.
