Dr. Theo Lee, Ph.D., Vice President and Chief Technology Officer of Headwaters CTL, LLC, described an advanced 20,000 BPD coal-to-ultraclean liquid fuels plant that has recently been commissioned in Inner Mongolia, China. Operating since early 2009, the plant is based on Headwaters' direct coal liquefaction and Axens' synthetic fuel hydrocracker. All the process parameters have been achieved. There are some equipment issues such as the coal feed through lock hoppers instead of let down valves. Although direct coal liquefaction posts a high stringent coal requirement (prefers to use a lower coal), it is more thermally energy efficient (low carbon footprint) and requires less investment than indirect coal liquefaction. Direct liquefaction is most suitable for gasoline but can be economically tailored for production of other fuels. Indirect liquefaction allows economic production of chemicals.
