Sulfur release was studied during the retorting of oil shale in a bench-scale reactor. H2S and COS were measured in retorting gas and sulfur element was determined in the semi-coke. Wangqing oil shale was selected as a sample in the tests. The results show that both two main factors affect the sulfur release during the samples distillation between 300°C and 600°C. The H2S releases below 550 °C, while COS escapes mainly in two stages of 300°C-450°C and 500 °C -600 °C.

<p>In situ measurements of the chemical compositions and mechanical properties of kerogen help understand the formation, transformation, and utilization of organic matter in the oil shale at the nanoscale. However, the optical diffraction limit prevents attainment of nanoscale resolution using conventional spectroscopy and microscopy. Here, we utilize peak force infrared (PFIR) microscopy for multimodal characterization of kerogen in oil shale. The PFIR provides correlative infrared imaging, mechanical mapping, and broadband infrared spectroscopy capability with 6 nm spatial resolution. We observed nanoscale heterogeneity in the chemical composition, aromaticity, and maturity of the kerogens from oil shales from Eagle Ford shale play in Texas. The kerogen aromaticity positively correlates with the local mechanical moduli of the surrounding inorganic matrix, manifesting the Le Chatelier’s principle. In situ spectro-mechanical characterization of oil shale will yield valuable insight for geochemical and geomechanical modeling on the origin and transformation of kerogen in the oil shale.</p>
