Investigation of the ROPE copyright (Recycle Oil Pyrolysis and Extraction) process performance on Sunnyside tar sand
The main objectives of this research were to determine the optimum pyrolysis temperature for Sunnyside tar sand and to verify the operability and efficiency of the ROPE process at steady-state conditions for production of feedstock materials. The experiments were conducted in the 2-inch screw pyrolysis reactor (SPR). Four 24-hour tests and one 105-hour test were performed in the 2-inch SPR using Sunnyside tar sand. The 24-hour tests were designed to predict the optimum pyrolysis temperature for oil yield. The 105-hour test was conducted to confirm the optimum pyrolysis temperature with sufficient operating time to reach steady-state conditions with respect to product compositions. The following conclusions can be drawn from the Sunnyside tar sand 2-inch SPR tests: (1) Sunnyside tar sand can be processed without any major operational difficulty by the ROPE process. (2) Oil yields greater than Fischer assay were obtained during the 2-inch SPR tests. Oil yield greater than 80 wt % of the bitumen was obtained from the 105-hr test. (3) The ratio of heavy oil to light product oil is strongly dependent upon the pyrolysis temperature and increases with a decrease in the reaction temperature. The gas yield increases with the increase in pyrolysis temperature but the residual carbon in the spent sand decreases with the increase in pyrolysis temperature, reaches the minimum at 675{degrees}F, and then increases with further increase in the pyrolysis temperature. ROPE process product oils from Sunnyside tar sand have market application as blending stocks for the production of diesel fuels, but they are not suited for the production of unleaded gasoline or high-density aviation turbine fuels. 3 refs., 3 figs., 17 tabs.
