SRCI process was very similar in concept to the PottBroche process and aimed to upgrade coal to produce a clean boiler fuel with a much lower ash and sulphur content than the original coal. The SRCII process, however, was to produce distillate products; the distinguishing characteristic of the process was the recycle of vacuum bottoms.

All coals, regardless of whether they are caking or coking coals, leave a solid carbonaceous residue at the end of the carbonization process. Chars, if heattreated to extreme temperatures, ≥2500 °C, do not form graphite, while cokes do. That is, chars are nongraphitizable, while cokes are graphitizable [A]. Type.
