초록정보

Pyrolytic carbon has been obtained in our experiment from the pyrolysis of propane by tumbling bed and stationary bed. The main object of our experiment is to compare various structures and properties of pyrolytic carbons obtained from two systems. The stationary bed consists of a fixed reaction tube equipped to be able to controlling the process variables such as the propan composition, total flow rate, reaction temperature and reaction time in the range of 12.5 to 100% $C_3H_8$, 0.5 to 21/min, 1100 to 1280℃, 30 to 60 min respectively. In the tumbling bed rotating the reaction tube, the process variables are temperature and R.P.M. in the ranges of 1030℃-1210℃ and 1.5-100 RPM respectively at the fixed propane composition (28% $C_3H_8$) and total flow rate (21/min). The results have shown that the reaction products are made up of columnar, carbon filament and soot in the stationary bed and isotropic carbon in the tumbling bed. And coating rate, density and apparent crystallite size of isotropic carbon are between those of columnar and soot. But its microhardness is greater than the other structures. From this results, the mechanism for the formation of the isotropic carbon can be known.
