Abstract:
1. A method of producing fullerenic products by combustion, comprising: introducing, through at least one introduction location of a primary chamber, a first carbon-containing fuel and a first oxidant so that said first fuel and said first oxidant react in the primary chamber to produce first combustion products and unreacted residue; introducing, through said at least one introduction location of the primary chamber, a second carbon-containing fuel and a second oxidant; said primary chamber configured so that said first combustion products and said unreacted residue are recycled, back-mixed, and reacted with said second carbon-containing fuel and said second oxidant to form a combustion mixture, the mechanism for back-mixing between (i) said first combustion products and said unreacted residue and (ii) second carbon-containing fuel and said second oxidant being laminar; and introducing said combustion mixture into a secondary chamber.
