Coal as Gasification Feedstock

If coal is intended to serve as fuel for industrial gasification processes, it is smart to borrow know-how for coal characterization from combustion research because of its long and comprehensive history. Hence, well-known analysis methods and classification schemes will appear, which must be always reviewed in the light of gasification conditions that differ from combustion in terms of oxidant (oxygen and steam instead of air), operation pressure (20-100 bar), and overall reducing atmospheres (products are CO and H2 instead of CO2, H2O). 

Industrial Coal Gasification Techntdoffes Covering Baseline and High-Ash Coal, First Edition. 

The overview provided in this chapter is limited to the relevant investigations and calculations that might be necessary to judge if a coal is suitable or not to a specific gasification process. Special emphasis will be placed on understanding the ash behavior during gasification as it is very different from combustion.
