The composition of pollutant gases (CO2, CO and SO2) during the co-combustion of Oil Shale (OS) and biomass wastes was studied in real time through thermogravimetric analysis (TG) coupled with a Fourier-Transform Infrared Spectrometer (FTIR). OS samples are from Mangrullo Formation (Uruguay). Biomass wastes were mixed with the OS at ratios 25%, 50% and 75% in mass of OS. Results showed that the emissions of pollutants per energy content of the mixture are related with the volatile decomposition and char reacting stages. CO2 emissions are significant during the volatile decomposition and subsequently combustion stage at the temperature between 400 and 500 °C. The profiles of CO2 against temperature exhibits one or two peaks, depending on the OS content of the sample and these emissions purely increased with the carbon content in the blends. The concentrations of SO2 obtained by the TG analysis showed that the amount released increases as the OS content rise. This work showed that the adding of biomass waste to the OS can improve the gas quality as reduces. Generally, the results showed that samples between 0 and 50% of OS-biomass produces lowest total SO2 emissions.

Direct Detection of Oil Shale Yields: A Laser-Induced Voltage Investigation

et al. 2019

The necessity of augmentation for oil shale explorations has led to increasing theoretical and technical requirements regarding online and direct detection of the organic content in shale. In this study, an ultraviolet laser with a wavelength of 248 nm is employed to analyze the oil shales with different oil yields and from different oil fields. Experimental results found that the laser-induced voltage (LIV) was monotonically related to the organic contents in the shale. Also, the LIV peaks linearly increased with an increase in the laser intensity and oil yield. Organics, like kerogen, and inorganic minerals reflected different energy bands. The higher the oil yield of the shale, the more the carriers were excited by the laser, indicating a stronger built-in electric potential. The microscopic structures, minerals, and kerogen were determined using a scanning electron microscope, X-ray diffraction, and Raman spectroscopy. The results showed that LIV can directly detect the organic content of oil shale for use in geophysical prospecting in the unconventional oil-gas resources industry.
