This chapter presents a comprehensive review of the effects of the physical and chemical properties of coal on the gasification process. These include coal reactivity (rank, macerals, porosity, surface area, mineral matter contents, etc.); ash and slag properties (mineral matter transformation, ash fusibility, slag viscosity, ash agglomeration, fouling, clinkering, etc.); coal particle size and fragmentation; and caking and swelling. Different considerations, such as gasifier types, syngas compositions and ash-related problems during gasification are also discussed. Moreover, methods for preventing ash-related problems during gasification are summarized.
