Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...

Hydrothermal Treatment of Low Rank Coal for Making High Solid Loading and Stable Coal Water Slurries
DownloadFall 2014
The objective of this research is to understand the effect of hydrothermal dewatering (HTD) on surface properties, stability and rheological behavior of lignite water slurry (LWS). The surface forces between coal particles are found to be attractive after HTD, which is proven by contact angle and...

During the past few decades, petroleum has been the main source of liquid fuels. On one hand petroleum reserves are declining, and on the other hand coal reserve is the most abundant fossil fuel known in the world. Liquefaction aims to convert solid coal into liquid fuels. Coal can be converted...

Solvent extraction of coal: Influence of solvent chemical structure on extraction yield and product composition
DownloadSpring 2012
In recent years the need for new carbon sources to supplement crude oil for the production of fuels and chemicals, again focused on coal as suitable candidate. Old and new technologies are being developed to convert coal in valuable products. An old technology such as solvent extraction of coal...

The stability of the ether bond affects coal dissolution during direct coal liquefaction and aliphatic ethers are reportedly the most reactive of the oxygenate classes during liquefaction. Some ether compounds are also persistent to high temperature during coal pyrolysis. The thermolysis of ether...
