Pilot plant tests on the hydrotreating of SRC-II process product indicate that this coal-derived feed is suitable for refining using advanced commercial petroleum processing technology. Experiments were completed to evaluate several different combinations of refinery processes for conversion of SRC-II to transportation fuels. Nitrogen in the whole SRC-II process product can be reduced to a concentration of less than 0.5 ppM in a single catalytic stage. Sulfur and oxygen can also be reduced to low levels; and at high severity, most of the aromatic compounds are converted to napthenes. The naphtha appears to be an excellent catalytic reformer feed, and the middle distillate meets the smoke point and stability specifications for jet fuel. As the processing severity is decreased, product nitrogen increases; and the product becomes more aromatic. In the latter case, further hydrotreating of the naphtha is required before it can be fed to the second stage of a catalytic reformer. Depending on the severity employed, it may be necessary to further hydrogenate the jet boiling range product for specification jet fuel. Experiments were made to determine appropriate conditions for these processing steps. Alternate processing schemes include hydrocracking and catalytic cracking. In this report, pilot plant results for a two-stage hydrocracker are presented. Early pilot plant results indicate that H-Coal whole process product can be hydrotreated to make a jet fuel similar to the jet fuel from SRC-II whole process product. Since H-Coal whole process product contains 1.5 wt % more hydrogen than does SRC-II product, the H-Coal product requires 700 SCFB less hydrogen during hydrotreating. Unfortunately, the ash and asphaltene impurities in the H-Coal product we have processed have made the pilot plant operation difficult.
