Definitions

  • FUTILE COMBUSTION OF CARBON DILEMMA Earth's entire present and expected human population cannot earn enough discretionary income to pay the cost of repairing damages that have occurred and are predicted to increasingly occur so long as the carbon in fossil fuels continues to be burned to support human earning endeavors.
  • the invention embodiments disclosed herein provide profit driven collection of carbon and hydrogen from substances that rot or burn to overcome the ominous carbon combustion dilemma that has been created by the industrial revolution.
  • Such carbon can be utilized to produce equipment that collects more energy from solar, wind, moving water and geothermal resources (every day in many applications) compared to burning the carbon one time.
  • Carbon enhanced equipment can thus sustainably continue to produce energy.
  • Coproduced hydrogen is combined with nitrogen and/or carbon dioxide from the air (or preemptively collected from more concentrated sources such as power plants, mineral calciners, ethanol refineries, bakeries, waste digesters, breweries, decaying permafrost and other unstable clathrates) to make liquid fuels that can be stored in existing gasoline, diesel or jet fuel tanks at ambient temperature and pressure.

  • Radiative, convective and conductive heat transfer from one or more resistive or inductive heaters 1 12 drives the dissociation reaction on the heated seed particles.
  • Occasional cleaning of the inductive or resistive heaters and/or insulator curtain 1 10 to remove excess carbon deposits can be provided by admitting an oxidant such as air or oxygen through port 142 of valve 140 for delivery through orifices 1 16 of tube nipple 1 14.
  • This occasional delivery of oxidant to the zone requiring cleaning quickly converts excess deposits of incandescent carbon into carbon monoxide and/or carbon dioxide to restore the electrical and/or radiative properties of the resistive and/or inductive components 1 12 and/or the radiation transmitting and/or re-radiating properties of insulator curtain 1 10.
  • the insulator curtain 1 10 is allowed to collect carbon deposits for the purpose of serving initially as a blocking curtain to keep components 1 12 from being fouled by carbon deposits from methane dissociation.

  • curtain wall 108 can be removed after achieving suitable loading of carbon deposits to serve in similar or other durable goods applications.
  • Rotary union 128 connects stationary tube 126 to provide delivery of gases through rotating tube 128 from the zone proximate to heating elements 1 12.
  • Gas delivery may include hydrogen, un-reacted feedstock hydrocarbon, e.g., methane and occasional flows of carbon monoxide, carbon dioxide and nitrogen if air is utilized instead of oxygen for removal of excess carbon deposits.

  • the orientation of orifices in tubes 133, 135, etc., for delivery of feedstock fluids can be more or less tangential to radiant heating tube 1 12 and/or presented in other suitable patterns for keeping one or more radiant tubes 1 10-1 12 relatively clean in operation.
  • adaptive control of the pressure that the hydrocarbon spray pattern is variably regulated can provide a reduced or greater rate of carbon particle and filament deposition compared to carbon deposits on curtain or screen media 1 10.

  • Hydrocarbon or another suitable carbon donor fluid is sprayed through orifices in a suitable number of delivery tubes such as 133, 135, 137 and/or other tubes to deflect carbon growth particles and/or filaments away from tube 1 12 to prevent fouling.

  • a suitable hydrocarbon such as one or more petrolatum constituents, various molecular weights of wax, petroleum jelly, natural gas constituents and/or renewable methane to provide highly desirable fiber strengthening, optical, electronic and/or other specialized physical or chemical capabilities.
  • such low cost prickly, fuzzy, bristly, or wooly carbon fibers and/or particles can reinforce equipment to collect more energy (every day in many applications) from renewable solar, wind, moving water or geothermal resources compared to burning such carbon one time. It is synergistic to utilize such prickly filaments or fibers along with such prickly particles to increase the fatigue endurance strength and other properties of composited components. This provides energy harvesting equipment with exponential energy collection advantages over burning such carbon one time, which causes highly objectionable amplification of the greenhouse gas global warming dilemma.
