Progress is reported on the HYTORT Process development work conducted from April 1 through June 30, 1980. Thermobalance tests have been conducted on samples of shale from each large multiton sample prior to large-scale tests and these test results have been fit with specific kinetic expressions. Approximately 80% of the instrumentation for the laboratory-scale reactor has been received. Fabrication of the reactor, feed hopper, and residue receiver is about 95% complete. Two successful moving-bed tests were conducted in the bench-scale reactor during this quarter. A large, 50-ton sample of the Lower Huron member of the Ohio Shale was mined and readied for shipment to IGT. Modification of the bench-scale steam-oxygen unit was completed. Spent shale from PDU tests was prepared for use in these tests. A set of five screening runs on New Albany shale oil and a set of four screening runs on Sunbury shale oil were conducted during this quarter. The nitrogen content of these oils was reduced to the 0.16 to 0.30 weight percent range in the bench-scale hydrotreating unit. Design of the laboratory test system for mist-size control studies was completed. Methods are being studied for measuring mist particle size. Shakedown and initial testing of the liquid-sealed lockhopper were performed during this quarter. Two runs were made in the PDU with Kentucky shales using a sample of the Cleveland member of the Ohio shale and a sample of New Albany shale. Samples for environmental analysis were taken during the PDU runs discussed above. On-line sampling equipment was installed prior to the PDU run with New Albany shale and samples were taken of the Stage 2 raw product gases.
