This report describes progress, during the period July 1, 1981 through September 30, 1981, in the development of techniques for the upgrading of coal liquids by the application of extraction technology. Studies were conducted to determine the feasibility of removing phenols from SRC-II naphtha and middle distillate by aqueous methanol extraction. Extraction feedstocks were prepared by mixing SRC-II naphtha and middle distillate and distilling into narrow boiling fractions. The fractions were analyzed so that phenols and nitrogen boiling range profiles could be determined. The phenols were found to be concentrated in the 280/sup 0/F to 500/sup 0/F fraction, while the nitrogen content generally increased throughout the boiling range. One-step and multi-stage laboratory batch extraction tests were first conducted to determine operating parameters. Then, continuous, frational extractions were carried out in a Scheibel extraction column. The work demonstrated that the phenols can be extracted efficiently and selectively from the appropriate phenols-containing heart cut. 15 figs., 15 tabs.
