In the Synthoil process for converting coal to a low-sulfur fuel oil, coal is liquefied and hydrodesulfurized in a turbulent-flow, catalytic packed-bed reactor. A slurry of coal in recycled oil is reacted with hydrogen at 450/sup 0/C and 2,000 to 4,000 psi in the presence of Co-Mo/SiO/sub 2/-Al/sub 2/O/sub 3/ catalyst. Turbulent flow of fluid prevents the coal's mineral matter from settling and plugging the reactor. In a /sup 1///sub 2/ ton per day pilot plant at PERC, the gross liquid product is centrifuged to remove unreacted solids, producing a low-sulfur, low-ash liquid fuel. The heat of reaction of coal-oil slurries with hydrogen is being determined in the presence and absence of catalysts at 2,000 to 4,000 psi and 400 to 475/sup 0/C, using a specially designed and constructed calorimeter. This drop calorimeter is now operational, and preliminary experimental runs are being carried out. The coefficients of heat transfer from Synthoil reactor fluids to heat exchanger surfaces will be determined in the following ranges of conditions: a pressure of 14 MPa and temperatures of 200 to 465/sup 0/C. Installation of the test unit has been completed, and heat transfer coefficient measurements with only hydrogen flowing have been started.
