Coal type: Coals of high rank can be gasified more efficiently than coals of low rank. The higher moisture and ash content of low rank coals require a higher degree of oxidation (more oxygen) to achieve slagging temperatures because of the energy needed to vaporize the moisture and melt the ash. Most recent studies have focused on high rank coals.
