Surfactant studies for bench-scale operation; Sixth quarterly technical progress report, October 1, 1993--December 31, 1993
A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the sixth quarter of work. The major accomplishments were (1) Completion of the distillation of the liquid product from coal liquefaction autoclave reactor runs with Illinois No. 6 coal at 400{degree}C, with and without surfactant and/or catalyst at pressures of 1700 psig, (2) Batch autoclave runs at 375 and 400{degree}C with 1 wt % lignin to Illinois No. 6 coal to further define the surfactant effect of sodium lignosulfonate, and (3) a preliminary economic evaluation of the application of the lignosulfonate surfactant in an industrial liquefaction process and a proposed conceptual plant design.
