PITCH MATERIAL MADE OF COAL TAR PITCH, PROCESS FOR PRODUCING AND USING THE SAME |
| 摘要 |
A new pitch material made of coal tar pitch, a process for producing the same and utilisations thereof. It has the following parameters: a) a mesophase content </= 2 %, b) a content of toluol-insoluble materials ( beta -resins) of 58 to 75 %, c) a content of material insoluble in quinoline </= 2 %, d) a softening point in the range of 200 to 300 DEG C, measured according to Krämer-Sarnow (KS), e) a content of volatile components </= 20 % and f) an ash content </= 0.06 %. The pitch material with a high coke yield of 80 to over 90 % can be used in the carbon processing industry to produce high quality carbon moulded bodies and pitch coke. In addition, it can be used as impregnating or bonding agent. |
