Current pilot plant results are presented for processing of H-Coal whole process product derived from Illinois No. 6 coal (Burning Star Mine): first, hydrotreating of the whole oil and, second, extinction recycle hydrocracking of the hydrotreated product. The 250/sup 0/F+ portion of severely hydrotreated H-Coal whole process product meets the jet fuel specifications for aromatics content, smoke, freeze, and flash points and almost meets the current specification for gravity and end point. The yield of 250/sup 0/F+ product is 90.4 LV % based on feed. The diesel fuel oxidation stability of 300/sup 0/F+ hydrotreated products is excellent, even without additives. In an accelerated fouling rate test, the denitrification fouling rate of ICR 106 catalyst was measured. At comparable conditions, the H-Coal whole process product is denitrified to a greater extent than the SRC-II whole process product. Deposits were formed in the preheater of the whole oil hydrotreater, which appear to be from either asphaltenes or soluble iron compounds in the feed. An alumina guard bed ahead of the catalyst successfully removes these contaminants. A large batch of low aromatic, denitrified H-Coal whole process product was prepared for downstream hydrocracking. In this preparation hydrogen was consumed by the oil at roughly 2100 SCF/bbl. The whole product from this hydrotreater was then cracked in an extinction recycle hydrocracker to make a 350/sup 0/F/sup -/ product. In this hydrocracking step, hydrogen was consumed by the oil at 800 SCF/bbl.
