Laboratory guidance and support for the development of the EDS coal-liquefaction process has been an ongoing activity throughout the EDS project. Initial bench-scale and small pilot-plant tests results were utilized in engineering studies and helped set the basis for design of the 250-ton/day pilot plant (ECLP). During the project life, the small pilot plants were used extensively to evaluate the yield and operability responses of the program coals. In particular, a considerable laboratory effort was expended during the last two years of the project in support of the 250-ton/day pilot-plant operations. These large-scale operations proved to be very successful, leading to a positive assessment of commercial readiness for the EDS process. This paper focuses on the extensive data base developed during the EDS program. A wide range of coal ranks has been evaluated in bench-and pilot-plant testing over a broad array of process conditions. The process understanding which evolved from this data base and applications of this understanding to control product distribution are discussed. A process model formulated from the data base was instrumental in guiding operations of the 250-ton/day ECLP. Yield predictions from the process model are compared with ECLP measured yields. Finally, the predictive tool developed for supporting EDS licensing activities is described. This generic coal model provides predictive capability for most coals of interest for EDS liquefaction. 10 figures.
