Fundamental Studies of Water Pretreatment of Coal
Description:
During the seventh quarter, water pretreatment experiments were done at lower pressures (1000 psig), with early H{sub 2}O injection or continuous H{sub 2}O injection, and with demineralized coals. In addition, a set of blank experiments was done with all four coals in helium at the following conditions: 350{degrees}C; 4000 psig; 20 minutes. An additional experiment was done with the Zap lignite at atmospheric pressure. Helium was used instead of nitrogen since it can be obtained in highly pure …
