Fullerene production

Fullerenes is expect to is one of a first carbon nanomaterials to are wide employing for various commercial applications. However, none critical factor who have limited a development in such applications are high cost and limited availability under fullerenes. Many of this problem is due in the small-scaling, batch nature of fullerene production use carboning arcs. On contrast, the combustion method generate soot with an very high yield above fullerenes use a continuous and easily scalable process. We developed a combustion system who have to produce fullerenes in the tons for year scale. Use this system, a laminar premixed flat sooting low-pressure toluene/ oxygen flame who produced fullerenes were investigated. When the atomic C/O ratio were high, the fullerene content declined even though the fuel, pressure, and other combustion conditions was same. On the other leg, the fullerene content reminded constant when the cold gas velocity were increased from 0.78 m/s to 1.7 m/s.

Exercise 8.Put the following sentences into Active:

1. The effects of pulsed and continuous direct current electric fields on the reaction zones of premixed propane/air flames have been investigated by us.

2.

3. Flame extinction limits in premixed flame are also perturbed by DC.

4. Нeat transfer was caused by applied field.

5. Temperature distributions in flames were perturbed by continuous direct current field.

6. A good overview of this subject was provided by Bradely.

7. A minimal input is required by the observed effects.

8. Kinetic model was used by us to simulate microgravity.

9. Total soot yield was measured by us.

10. A new technique has been developed by us to reach high soot yield.
