Basics

This is a term for Charcoal Fuel that has been processed via techniques similar to those used for "Ultra Clean Coal " ( Coal Upgrading and Coal Washing )
Ultimately it is for all intensive purposes pure carbon
Thus the Ash Content should be near zero, and Syngas production is standardized no matter the Feedstock for the charcoal
Also along with Ash Handling and Utilization and Brine-to-x it allows for recovery of various Minerals and other Chemicals of use
Can be abbreviated as "UPCF" (This is advantageous over UPC as that acronym is already heavily used for other things)
As with Ultra Clean Coal if powderized sufficiently it can be used in Internal Combustion Engines and Gas Turbine Burner without a seperate Gasifier system

Potential Issues

Differences between Fossil Fuel Coal and Charcoal (ie especially outside of peat (and maybe lignite) one is a Sedimentary Rock and one is recently charred organic matter) leading to cross application of protocols infeasible/complicated
- I think this will actually be in our favor. I need to look into Ash Content and Composition of Various Biomaterials / biofuels, BUT almost certainly none of the

nasties" in coal combustion byproducts, and short of dirt collected in the harvesting process little to no non-ash minerals etc

- So again if my hypothesis is right , some reduction (chipping, grinding, and maybe even Ball Mill etc powderization or High Shear Mixing ), water wash, then maybe acid then base leaching, then another water wash should work VERY well
If a fine mesh size and high purity charcoal fuel is produced re-pelletization/briquetting may be difficult
- It might require a binder, which would be a bit counterproductive for most reasons UPCF would be of use (If the binder has ash that eliminates that advanage, if oily/greasy that issue reappears, not easily made into activated carbon etc)
- This would have potential synergy with the Carbon Powder+ Paraffin Wax + Fire Retardant Putty / Bentonite Clay alternative i was plotting for a Carbon Sequestration in Construction / Carbon Sequestration in Materials kind of application
  - ie essentially a fuel version, and an inerted/fire resistant version
