The Optimization Of Lowrank Coal Grinding For Transport
May 01, 2012 KBR transport gasifier is an effective process for gasification of low-rank coal. However, a feed coal for this gasifier has a narrow particle size distribution. Grinding parameters on hammer mill was investigated by Taguchi method. Aperture size of screen in the second hammer mill was the most significant factor. The ratio of product loss was 10.18% under the optimized condition.

Early Days Of Coal Research Department Of Energy
Rather than dissolving coal directly into a liquid as in the Bergius process, the Fischer-Tropsch method first transformed coal into a gas, then chemically rearranged the gaseous molecules into liquid fuels and chemicals. The second plant at Louisiana, MO, was completed in 1950 and began full operation in 1951.
