Continuing work on deashing SRC-I filter feed has yielded deashed oils containing 0.004 wt % ash or less. The lowest reject bottoms yield was 18.8 wt %. This fails to meet the target of 15% maximum rejection. A summary of the deashing work on SRC-I filter feed has also shown that rejection decreased with use of higher boiling point solvents, with addition of up to 10% light aromatic component to the solvent, and with increased operating temperature. The hydrotreatment of the deashed oil derived from SRC-I filter feed yielded oils containing 9.99 wt % and 10.17 wt % hydrogen. Recoveries of oil ranged from 99.20 to 99.65 wt %. Hydrogen consumption was 1080 to 1090 SCFB hydrogen. Two deashed oils derived from UOP coal liquefaction product have been catalytically cracked. Conversions ranged from 44 to 60 vol %.
