operating conditions (mainly temperature and oxygen/carbon ratio) all affect slagging behavior. Because coal has varying ash …. In Part I, we review the main types and the operating conditions of entrained-flow gasifiers and coal properties used in … IGCC plants; we identify and discuss the key coal ash properties and the operating conditions impacting slag behavior …

Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to … and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be … notable of these being H-Coal, Exxon Donor Solvent, Solvent Refined Coal, and Two Stage Liquefaction. The key elements of …

Biomass is relatively cleaner than coal and is the only renewable carbon resource that can be directly converted into … thermal conversion of coal and biomass as a blend. Most notable topics reviewed are slagging and fouling caused by the …-conversion with coal. The catalytic activity is most noticeable when blended with high rank coals. The synergy during co-conversion is …

The current study is focused on controlling sulphur emissions by pre-treating coal to remove sulphur prior to … value recoveries were significant. Increase in oxygen content is reported as a measure of carbon loss. The coal samples were …

parameters that need to be studied. The accurate formulation or representations of the (transport) properties of coal present a … discuss the key coal ash properties and the operating conditions impacting slag behavior. …

Understanding and modeling of coal and biomass pyrolysis assume particular importance being the first step occurring in … materials, which represent very different classes of energy source: a microalgae biomass and a sub-bituminous coal. The model …

is still dominated by crude oil but has expanded to incorporate new energy sources in the form of coal, natural gas, and …
