Definitions

  • This disclosure generally relates to processes for the production of fuels for pressurized pipeline carriers designed for gaseous fuels such as methane and/or occasionally using such pipelines to transport liquid fuels.
  • Methane produced by these and other processes has been proven to be detrimental to the environment when released into the atmosphere or hydrosphere.
  • methane and other greenhouse gases collect and form an optical absorber, filter or radiation barrier in the atmosphere that prevents infrared radiation from escaping through the air into outer space. Instead, the greenhouse gases absorb and re-emit the infrared radiation, which can result in unnaturally and adversely increasing average surface temperatures on earth.
  • SI engines are fueled by octane-rated petrol or gasoline and utilize spark-ignition (SI). Diesel engines utilize cetane-rated "diesel fuel” in higher compression ratio engines that rapidly compress and heat the air for achieving compression ignition (CI). Spark-ignited SI engines are lightweight and operate at higher speeds to achieve greater power-to-weight ratios than compression-ignited CI engines. Diesel engines operate at lower speeds and are heavier and are considerably more expensive to manufacture.
  • SI engines have compression ratios that range from about 6 to 10 and operate at speeds of about 2000 to 6000 RPM compared to CI engines with compression ratios of 14 to 24 and operate at speeds of about 450 to 2100 RPM.
  • CI engines are more expensive to manufacture, considerably heavier, noisier, require complex high-pressure fuel injection systems, along with larger starter motor systems in comparison with SI engines.
  • Diesel fuel is pressurized up to about 2,000 Bar (30,000 PSI) in order to produce sufficiently fine sprays of fuel droplets that are directly injected to rapidly achieve ignition in rapidly compressed hot air in efforts to diminish objectionable emissions of unburned fuel smoke. Such fuel pressurization and friction losses incurred to produce higher compression pressures requires CI engines to overcome
  • the instant application relates to the production and utilization of methane to produce methanol and other liquid energy storage fuels.
  • Problematic productions of greenhouse gases such as sourced by landfills, sewage, and agricultural wastes along with coal seam and flare-gas constituents and/or products are overcome by conversion to valuable carbon and co-produced hydrogen that is utilized for improved
  • hydrocracking processes to produce methane and/or liquids for pipeline transportation to industrial plants that process such feed stocks into durable carbon and net hydrogen fuels.
  • methane is reacted with water to produce methanol and hydrogen.
  • the hydrogen product can subsequently be used to produce various products including ammonia, urea, formic acid and many other products such as by reacting the hydrogen with nitrogen and/or carbon dioxide from sources such as the atmosphere or by preemptive collection from more concentrated sources.
  • Heat can be applied to either nitrogenous energy carriers such as ammonia or urea or to
  • carbonaceous energy carriers including fuel alcohols such as methanol in order to produce hydrogen that can be used in a variety of applications including ovens, furnaces, and engines such as fuel cells and/or heat engines.
  • the methane used in the processes and apparatus described herein can be obtained from byproducts produced by human-implemented processes.
  • the methane can also be obtained from sources that leak into the atmosphere by naturally occurring events and processes involving virtually anything or substance that ordinarily rots or burns.
  • Such methane can be dissociated into hydrogen for fuel or production of chemicals and carbon for producing durable goods.
  • Each ton of carbon that is thus prevented from rotting or burning prevents 3.66 tons of C0 2 greenhouse gas
  • an exemplary reactor vessel in order to carry out the reaction of methane and water.
  • the reactor vessel can include two concentrically positioned tubular shells.
  • the interior space of the interiorly positioned tubular shell can define a first reaction zone wherein a carbon-donor such as methane and an oxygen donor such as water react to produce methanol and hydrogen.
  • the annular space between the interiorly positioned tubular shell and the exteriorly positioned tubular shell can form a second reaction zone where hydrogen and nitrogen react to produce a nitrogenous substance such as ammonia.
  • the hydrogen for the second reaction zone can be provided by transporting the hydrogen produced in the first reaction zone through the interiorly positioned tubular shell, which may be made of hydrogen or hydrogen-ion permeable materials.
  • the reaction vessel can be a standalone system or can be incorporated into other equipment, such as an engine.
  • methanol and ammonia produced are high energy fuels that can be transported using existing infrastructure, such as storage tanks and pipelines repurposed from gasoline and/or diesel fuel applications.
  • the conversion of carbonaceous intermediates including alcohols such as methanol and/or nitrogenous substances such as ammonia and urea to hydrogen provides a relatively clean fuel source and can thereby reduce or eliminate dependency on non-renewable and dirtier fuel sources.

  • Methane can be separated from other primary natural gas substances by compressing and rejecting heat to cool the mixture followed by turbo-expansion to produce about -100°C to liquefy the ethane, propane, butane, pentene, and/or hexane.
  • the separated methane gas can be transported by conventional natural gas pipeline operation.
  • Additional methane for delivery by gas pipelines can be produced by thermal dissociation of higher molecular weight or mass hydrocarbons C x H y in which "x" exceeds the numeric value of one (1 ) such as ethane, propane, butane, pentane and/or hexane to produce carbon.
  • the co-produced hydrogen is utilized to hydrocrack one or more of the higher hydrocarbons to produce methane for delivery by conventional gas pipeline operations.
  • the methane can remain mixed with other primary natural gas substances for thermal dissociation to produce carbon and hydrogen and the hydrogen can be utilized to hydrocrack the remaining higher molecular mass or weight hydrocarbons to produce methane for transportation by conventional gas pipeline operations.
  • the same or other pipelines can be used to transport the liquids at sufficient pressure to stabilize the separated mixture as a liquid.
  • the pressure required for stable pipeline transportation as a liquid mixture is about 100 to 700PSI or more.
  • Dalton's and/or Raoult's and/or Henry's Laws the lower the concentration of the more volatile constituents such as ethane, propane and/or butane, the lower the stable liquid transport pressure can be.
  • liquid mixture can be transported at certain times by operation of the natural gas pipeline in a liquid transmission mode at a temperature and pressure that is maintained to at least be sufficient to prevent conversion of any constituent to gas.
  • a liquid such as an ether, ketone, aldehyde, or alcohol is produced to serve as a liquid that receives ethane, propane and/or butane to provide for pipeline transport as a pressurized liquid.
  • This is another application according to Henry's Law that provides for the solubility of a gas absorbed in a liquid to be directly proportional to the partial pressure of the gas above the liquid.
  • the operating pressure of the liquid pipeline can be at least approximate the sum of the partial pressures of the mixture constituents in accordance with Dalton's Law and/or Raoult's Law as needed to assure efficient pipeline operation and transmission.
  • a method for producing a liquid fuel such as carbonaceous or nitrogenous substance such as ammonia, formic acid, or an alcohol such as illustratively shown regarding methanol from methane generally includes one or more events summarized as step 100 of reacting methane with water to produce liquid methanol that can be separated from hydrogen.
  • the reaction of methane and water can be carried out according to Equation 1 A in an electrolysis cell such as disclosed in co-pending U.S. Patent Application Serial No. 13/584,748 and/or by the synergistic combination of an electrolysis and anaerobic digestion system to provide the net process summarized as follows: CH 4 + H 2 0 -> CH 3 OH (1 A)
  • methane and water can be reacted in a thermochemical process that may utilize steam such as supercritical steam as the oxygen donor to supply the heat needed to convert methane to carbon monoxide and hydrogen as shown in Equation 1 B.
  • steam such as supercritical steam as the oxygen donor
