  • Patent number: 10758842
    Abstract: Multiple site purification can be achieved by a small plastic portable voltaic inspissation unit in a box configuration. Each unit may feature an air hopper, a recirculation line, a gas diffuser, a centrifuge, a decanter, and multiple anodic and cathodic voltaic inspissation plates that may direct fluid through a box in a meandering or serpentine fashion. Multiple devices may be present or omitted, and retention times may be varied both by the presence or absence of recirculation and the flow rate accomplished by use of different metal in the plates depending on purification goals. Air may be injected interstitially prior to passage into the box to aid in purification, and ultimately both ease of transport and substantially improved purification percentages may be achieved relative to prior systems.

  • Patent number: 10730751
    Abstract: A system and process for producing carbon nano-materials is disclosed. A carbonate material such as Li2CO3 is heated via a furnace to transform into molten carbonate. CO2 is bubbled into the molten carbonate. The molten carbonate is subjected to electrolysis by passing current from an anode to a cathode. A transition metal nucleation agent is added to result in nucleation sites that grow carbon nano-materials at the cathode. This process separates oxygen at the anode and carbon nano-materials at the cathode. The characteristics of the carbon nano-material may be controlled by varying current density, feed gas, transition metal composition, temperature, viscosity and electrolyte composition.
