To produce hydrogen from coal, the process begins with partial oxidation, which means some air is added to the coal, which generates carbon dioxide gas through traditional combustion. Not enough is added, though, to completely burn the coal only enough to make some heat for the gasification reaction. The partial oxidation also makes its own ...

Syngas (the term is short for "synthesis gas") is a mixture of carbon monoxide and hydrogen gases. It is used to make ammonia, methanol, other industrial chemicals and fuels. The most common process for creating syngas is coal gasification, which uses steam and oxygen (from air) at high temperatures, a process that produces large amounts of ...

Heat was provided by combustion of coal with air and then the air was replaced with steam to gasify the hot char and produce syngas, a combustible mixture of carbon monoxide and hydrogen. Fontana called the resulting coal gas "blue water gas," because it produced a pale blue flame when burned in air (Probstein and Hicks 2006).
