Basics
- A Process by which Lower Grade Coals are "Upgraded" to a Product Functionally Identical to Higher Grade Coals
- Can be done via washing, drying/pyrolysis, and briquetting/pelletising
- The main goal is to reduce Ash Content and increase the Heating Value
- Due to Fossil Fuels obviously not being part of OSE's Strategy, this page is intended as a place to have information on this technolgy placed for reference in developing the Charcoal Fuels Workflow especially in regards to Ultra Pure Charcoal Fuel
Methods
Washing
- A Patent Titled "Process for preparing ultra-pure coal by using acid-alkali method" (Seems to be lab scale though? Odd and some potential translation issues, but interesting nonetheless)
Briquetting / Pelletization
- An Article by "Mining Review" Titled "Coal fines waste pelletising technology launched"
- A Product Page by ACAN on their Carbon Black Briquetting Technology Titled "BRIQUETTE MAKING OF CARBON BLACK FROM PYROLYSIS PROCESS OF SCRAP TYRE"
