A fundamental study on the dependency of hydrogen and carbon contents in the volatile matterof coke on temperature and particle size has been carried out.
The results obtained are as follows
1) Small size coke (or coke breeze) contains more hydrogen in volatile matter than large sizecoke.
2) The degree of volatilization of hydrogen depends on both of temperature and particle size, butthe effect of the former is more remarkable.
3) Main elemental components in the volatile matter are hydrogen and carbon, and the C/H ratiovaries from 2.0 in case of small size coke to 2.6 in case of large size coke.
4) Experimental formula expressing the dependency of the hydrogen volatilization on temperature and particle size are obtained.
