Claims6
A process for preparing granulated particles of a carbonaceous material comprising;
- pulverizing carbonaceous material at a temperature of 100° F. to 160° F. (37.8° C. to 71.1° C.) to produce pulverized carbonaceous material;
- sizing the pulverized carbonaceous material to produce sized, pulverized carbonaceous material;
- briquetting the sized, pulverized carbonaceous material to produce briquetted carbonaceous material;
- crushing the briquetted carbonaceous material to produce crushed, briquetted carbonaceous material and granulated briquetted material;
- and
- sizing the crushed briquetted carbonaceous material.
