Abstract
The CPC-process proposed previously, a technique for pretreating the coal charge of coke ovens, and the effect of combining the CPC-process with the briquette-blend coking process and the addition of caking additives were investigated in order to broaden the possible applications of the CPC-process. The investigation yielded the following results:
1) By applying the CPC-process, it was possible to improve the strength, DI15015, of coke even when a high-quality coal charge is used. The other processes cannot produce as great a relative improvement as the CPC-process.
2) An excellent composite effect can be expected by combining CPC-process with either of the other processes. Therefore, the CPC-process has been established as a fundamental prerequisite in techniques for pretreating the coal charge for coke ovens.
3) The CPC-process is a method which reinforces the structural strength of coke, and cannot be expected to improve the quality of coke carbon. Therefore, it is not reaso-nable to expect an improvement in strength after CO2 reaction through combining this process with other processes.
