Mild coal pretreatment to improve liquefaction reactivity. Final technical report, September 1990--February 1994
Description:
Recent research efforts in direct coal liquefaction are focused on lowering the level of reaction severity, identification and determination of the causes of retrogressive reactions, and improving the economics of the process. Ambient pretreatment of coals using methanol and a trace amount of hydrochloric acid was extensively studied in connection with low severity coal liquefaction. Ambient pretreatment of eight Argonne coals using methanol/HCl improved THF-soluble conversions 24.5 wt % (maf b…
