Tests have been carried out to quantify the variation in permeability of Texas lignite with drying and with applied stress. It has been shown that the matrix permeability of lignite may be increased from effectively zero to the order of 10 darcies by removing about 20 percent by weight of water. In addition, an increase of confining pressure after drying will reduce the permeability, but only

The specification discloses lignite pellets which are relatively hard, dust resistant, of generally uniform size and free from spontaneous ignition and general degradation. Also disclosed are methods for making such pellets which involve crushing as mined lignite, mixing said lignite with a binder such as asphalt, forming the lignite binder mixture into pellets, and drying the pellets.

When the drying degree is 0.3 and DNI is 0.5 kW / m 2, the economic analysis indicates that the simple payback periods for a conventional lignite power plant, SDPP, and SEDPP are 2.38, 3.20, and 2.53 years, respectively. In addition, the solar-to-electricity efficiency declines at a decreasing rate with increasing drying degree.
