Application of Catalytic Coal Gasification

Broad studies [27,35] have been carried out revealing that especially potassium carbonate, sodium carbonate, calcium salts, and iron are the prime candidates for commercial use. As all substances are linked to some disadvantages, attempts have been made to combine catalytic effects in mixed catalyst systems (e.g., hematite and potassium carbonate) [30]. Also, with a focus on availability and the inexpensiveness of raw materials for catalyst mixtures, calcium and iron, derived from wastewater streams of the steel industry, have been found to offer reasonable performance [27,28,31].
