Carbons until now
Precursors come from good raw materials such as coal tar and FCC-DO
No designed technology. Only experience is Know-how.
Developed countries who have long history of development only get chance to produce the advanced carbons such as T-800 and premium class needle coke.
Carbons of general performances are only produced in under-developed countries
During last decade, we recognized carbon materials are the best key materials for energy-saving and environmental protections.
Pitch and coke based carbon technology only get a markets for applications

Nano-carbons
29
• Fullerenes, carbon nano-cages, carbon onions, … • Carbon nanotubes, carbon nanofibers, carbon nanowires • Graphene oxides, graphenes
Nano-carbons have been intensively studied during last 30 years.
Industry for large consumption was failed to achieve.
Successful in the science level but failed to attain to engineering one No target specifications
Nano-carbons made us recognize that carbons are key materials for energy-savings and environmental protections. Nano-carbon science informed to us many specific properties of carbon materials and possible routes for design.
Is it possible to design the carbon materials using conventional raw materials or precursors? What we have to do for it?
