The purpose of this report is to present progress to date on the biological upgrading of coal liquids. This three-year study focuses on surveying of known microorganisms for S, N, and O removal and aromaticity reduction. Isolates from natural sources will also be sought for these reactions. The performance of these cultures will be optimized and evaluated individually and as a mixed culture. The best cultures will be selected for performance evaluation in continuous submerged culture experiments in constant-stirring bioreactors. Reactor design and product removal processes will be projected and the economics of this technology compared with conventional methods. (VC)
