ABSTRACT
Coal is relatively abundant energy source compared with other fossil fuels. Regardless of its abundance and a long history of usage, an inconvenience of its use reduces coal consumption at present. Coal as a solid fuel has a big problem of remaining ash in its use. Ash free coal has been attempted to overcome the problem. A trend of producing technologies of the ash free coal is described widely in (Kim & Lee 2012). Possibilities and effect of hydrogen production via steam gasification of ash free coals is presented in (Kim et al. 2013). In the same work also a comparison of steam gasification reactivity of AFCs and raw coals is described. Also more about gasification of AFC and using AFC as fuel for a direct carbon fuel cell can be found in (Lee et al. 2011, Kong et al. 2014).
