Brief Review of Thermal Graphitization of Coals and Carbons

摘要

1. US Has 250 - 300 Year Supply Coal 2. Approximately 1-1.1 billion tons/year Produced from 1990 - 2014 (EIA) 3. 755 Million Tons in 2018 4. US Coal - Most Used for Generation Electricity 5. Retirements of Older Coal-Burning Power Plants 6. Inexpensive Natural Gas 7. Activated Carbons, Chemicals, Steel, Exports 8. Additional Uses/Products/Markets Welcomed. 1. Multi-Billion Dollar Annual Industry 2. Various Precursors 3. Thermal Formation 4. Edward Ache son 1890 5. Making Silicon Carbide by Heating Coke and Sand to 3000°C 6. Form Graphite at Even Higher Temperatures (4000°C) 7. By Thermal Decomposition of Silicon Carbide 8. Carbon + Sand → Silicon Carbide (Carborandum SiC) → Graphite 9. Anthracite an Optimum Feed for His Process.
