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.

States has far more coal than gas and petroleum (compare Figures 71, 81 and 91). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
