Abstract
This program is aimed at establishment of the techniques for milling of brown coal treated by primary dehydration and slurry adjustment, and secondary hydration plant, as part of the project for developing the techniques for liquefaction of brown coal. Brown coal (Australian Yallourn coal) treated by primary dehydration, solvents (creosote and decrystallized anthracene), and catalysts are used as the stock samples, to investigate the coal characteristics with respect to milling crushability, dehydration and liquefaction reactivity, and the slurries are prepared by changing coal charge rate, solvent and preparation temperature, to collect the data regarding, e.g., coal concentration, coal particle size, moisture level and liquefaction reactivity. It is found that milling crushability tends to decrease as coal charge rate or solvent/coal ratio increases whether creosote or decrystallized anthracene is used as the solvent. Milling crushability is unaffected by slurry preparation temperature. Content of residual moisture in the slurry decreases to 1% or less, when slurry preparation temperature is increased to 100 degrees C or higher. Liquefaction reactivity of the slurry shows slight dependence on slurry preparation temperature, when it is increased to 180 degrees C. (NEDO)
