This program combines a research study on Catalytic Expanded Bed Hydroprocessing of Coal Extracts (Task 1) and the operation of an Integrated Two-Stage Liquefaction Process Development Unit (Task 2). The two tasks are to run con-currently. Two runs of the Parametric study of Task 1 were completed. All units of the Integrated PDU started up with the first stage, the short-contact time reactor, using foreign pasting solvent in this quarter. The parametric Study was interrupted for about one month to replace feed lines, transfer lines and check valves that had become corroded. All Task 2 units were in operation in this quarter. Short-contact-time (SCT) runs with Koppers Creosote Oil solvent and reactor outlet temperature of 860/sup 0/F were made with no operating difficulty. The coal space rate was varied between 111 and 247 pounds of coal feed per hour per cubic foot of reactor with no effect on conversion which was 91 +- 2% of moisture, ash-free (MAF) coal. Hydrogen consumption varied from 0.6 to 1.9% of MAF coal. Preasphaltene content of the extract increased with coal space rate from 29 to 44% of the solids-free extract. The deasher successfully deashed the SCT extract and provided a low-ash feed to the LC-Finer. The LC-Fining yields from this extract agreed well with runs made under the preceding contract with SCT extract made at Wilsonville and deashed by Lummus. The LC-Finer also had no difficulty hydrotreating extract that had by-passed the deasher. Per-pass 850/sup 0/F+ conversions in the LC-Finer were 35 to 49 vol. %.
