Fuel independence through the combined efforts of the U.S. Government and Silver

Due to their high inherent moisture levels, low-rank coals (LRCs) were not considered good feedstocks for Texaco gasification. High-rank bituminous coals and petroleum coke were preferred feedstocks to make concentrated slurries for feed to Texaco gasifiers. However, the development of Silverado’s hydrothermal treatment process enables LRCs to be formulated into low-rank coal-water fuels (LRCWFs) with solids content approaching those of high-rank bituminous coals and petroleum coke. Thus, hydrothermal treatment will make it possible to apply Texaco gasification to be extended to all ranks of coal; in particular, Silverado’s LRCWF.
