Feedstock Source. Three feedstocks were used in this study. All were derived from Uinta Basin, Utah Tar Sand deposits. A Sunnyside bitumen was solvent extracted by procedures previously reported (6) from a freshly mined sample obtained from the old Asphalt Quarry northeast of Sunnyside, Utah. An Asphalt Ridge bitumen was extracted similarly from a sample freshly mined from... 

Hydropyrolysis Process. Two hydropyrolysis reactors were used in this study. The Sunnyside and Asphalt Ridge bitumen were processed in a reactor consisting of a coiled stainless steel tube 3/16" i.d. x 236" long. This reactor has been previously described by Ramakrishnan (1). The TS-IIC oil was processed in a reactor originally developed for short residence time coal liquefaction. This reactor also consists of coiled stainless steel tubes 3/16" i.d. The length of this tube system can be varied from 20 to 120 feet, and has been previously described by Wood, et al. (10). The length of the reactor for runs reported in this paper was 100 feet. Average residence times were calculated from the volumetric flow rates and the reactor volume at process conditions. The reaction mixture, which is predominantly H, was assumed for purposes of this calculation to behave as an ideal gas. The reactors were pre-sulfided with H S to inhibit catalytic reactions from wall surfaces.
