Deashing of UOP coal liquefaction product, using the UOP Demex process, has been completed. Three rejection levels of 17, 30 and 26 wt % were attained. Ash content of the composite product was < 20 ppM. Fixed bed hydrotreating of the deashed oil was completed. A 0.75 wt % increase in hydrogen content was obtained under relatively mild operating conditions. A second coal liquefaction operation was completed, using the hydrotreated deashed oil as solvent. A 90 to 93 wt % (MAF basis) coal conversion was achieved. Demex deashing of this second liquefied coal product is to be started in July.
