This work is being done in support of the development of processes for converting coal to liquid fuel of low sulfur content, suitable for use in power production. Most of the effort is intended to produce information applicable to the SYNTHOIL process. In this process for converting coal to a low-sulfur fuel oil, coal is liquefied and hydrodesulfurized in a turbulent-flow, catalytic packed-bed reactor. First, a slurry of coal in recycled oil is reacted with hydrogen at 450/sup 0/C and 2,000-4,000 psi in the presence of Co--Mo/SiO/sub 2/--Al/sub 2/O/sub 3/ catalyst. The turbulent flow of fluid prevents the coal's mineral matter from settling and plugging the reactor. Then, the gross liquid products are centrifuged to remove the unreacted solids. The centrifuged liquid product is a low-sulfur, low-ash fuel. The program involves four tasks: (1) heat of reaction of H/sub 2/ with coal slurries; (2) heat transfer coefficient; (3) additives to facilitate separation of solids from liquids; and (4) catalyst testing.
