ピッチ類の石炭改質機構

抄録

In order to confirm the effects of pitch on the carbonization, a few experiments on the base of pitch with high sulfur contents were conducted by use of EPMA and microscope. These results are described in this paper.
From these experiments, the following effects of pitch were recognized.
1) Compatibility between pitch and coal
2) Increase and improvement of anisotropic texture.
These modification of fects mentioned above were recognized in solvent fractionation of the range from n-heptane insoluble to CS₂ soluble.
These methods are available for the quantitative analysis of the pitch of fects.
