option is to convert coal into high quality, clean burning transportation fuel. There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s.

This history of coal hydrogenation shows the difficulties Bergius faced in expanding his process from the laboratoryscale to a small industry. The major problems he confronted and successfully solved were: (1) providing enough hydrogen gas to convert coal into synthetic petroleum, (2) working at the high pressures required for the conversion ...

Nitrogen goes through a process called water washing, which transforms it into ammonia, and that is turned into farm fertilizer. After distilling, converting, and treating the crude oil, it is blended to create the finished products that we recognize. Blends of several products help make sure that the gas or fuel is the same every time.

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.
