Experiments have been completed that were designed to determine the emission characteristics of modified in situ oil shale retorts. A series of pilot plant scale, oil shale retort tests using oil shale from Occidental's future commercial suite have been conducted. The effects on emissions of the size of particle being retorted were investigated as well as the effects of using an air/steam mixture to support the combustion. The results demonstrate that H/sub 2/S and ammonia are the dominant species of concern. These gases occur in the offgas in the thousands of a ppm range. Carbonyl sulfide and other organosulfur species were detected, but their concentrations were in the tens of a ppm range or lower. Measurements of arsenic and mercury levels in the offgas also were made. Arsenic and mercury levels averaged well below the ppm range and were not detectable in most samples.
