Surfactant studies for bench-scale operation
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 second quarter of work. The major accomplishments were (1) completion of coal liquefaction autoclave reactor runs with Illinois No. 6 coal at processing temperatures of 300, 325, and 350[degrees]C, and pressures of 1800 psig, (2) analysis of the filter cake and the filtrate obtained from the treated slurry in each run, and (3) correlation of the coal conversions and the liquid yield quality to the surfactant concentration. An increase in coal conversions and upgrading of the liquid product quality due to surfactant addition was observed for all runs.
