WebA novel mixed catalyst–sorbent pellets for coal steam gasification was developed. • A maximum hydrogen yield of 80% was obtained from coal steam gasification at 700 °C. • The pellets with a catalyst content of 50% demonstrated the best performance. • Lignite coal produced twice more hydrogen than sub-bituminous coal did. • WebSolvent refining removes sulfur and particulates from coal by the use of hydrogen in a reaction system at elevated temperature and pressure. In this process, a substantial portion of the coal is dissolved by an internally generated solvent. Particulates are removed by filtration or other methods. About 70 percent of the sulfur is converted to hydrogen sulfide …

Introduction Coal Coal is a non-renewable, combustible, hard, black solid substance, consisting chiefly of carbonised plant matter, found mainly in underground seams and … WebAs has been found, the presence of 6–16 wt% MgO in bio-ash and coal ash exerted little influence on the ash fusion temperature. However, the slag flowability is slow for a relatively high viscosity of the bio-slags. In contrast, the coal slags flew much faster, although the formation of spinel crystals was confirmed in the high MgO content.
