This paper briefly describes the research status of oil shale pyrolysis technology and the main factors affecting oil shale pyrolysis, with emphasis on four kinds of commonly used catalysts: The effects of natural minerals, metal compounds, molecular sixes, and supported catalysts on the pyrolysis of oil shale were discussed. The changes of the pyrolysis mechanism and product composition of oil shale with the addition of different catalysts were discussed. Finally, the development direction of preparation of new catalysts was discussed, in order to provide a prospect for the development and utilization of unconventional and strategic alternative energy resources around the world.

Oil shale resources is a new energy has a huge potential for development, as the complement and alternative energy of the oil and gas, more and more people pay attention to it. China's oil shale resources are widely distributed and reserves are huge, but current mining methods are still primitive, mainly to direct exploitation, exploitation efficiency is low and ecological damage is serious, it will be replaced by in-situ mining methods in the future. This paper summarizes the research of oil shale in situ mining, aims at the problems of that the conduction of heat efficiency is low and the outlet channel is less which exist in the in-situ mining at the present, and put forward the concept of in-situ broken that is using some methods to make the oil shale change from huge to small block in the initial stage of the in-situmining, further in-situ heating, mining of oil shale,and put forward the method of in-situ noncontact wind breaking oil shale, this method using the crushing wind to break the oil shale, having high feasibility. This paper did in-depth research on the in-situ mining, and it can provide a reference for the development and utilization of oil shale resources.

Oil shale samples from the Ellajjun area south of Jordan were pyrolyzed in different conditions and environments. Sulfur of shale oil was determined using x-ray fluorescence (XRF). Generated products swept from the retort by several sweeping media; they include nitrogen, water vapor, hydrogen, and mixture of nitrogen and water vapor. Other conditions are 2–11 mm particle size, 1 atm operating pressure, and 410–550°C temperature range. The sulfur content of shale oil was found to be 12 wt % for hydrogen pyrolysis, while water vapor at 1 atm decreased this value to 7 wt %. Hydrogenation of oil shale resulted in 12 wt %. the sulfur content of shale oil being at 420°C, and then reduced to 10.3 wt % at temperatures higher than 470°C. When water vapor is added to nitrogen, the sulfur in the oil shale is increased by 4 wt %. Water vapor sweeping gas increased the sulfur of the shale oil from 6.5 wt % to 8.1 wt % compared with a nitrogen pyrolyzing medium. Retorted shale analysis showed 44 wt %, and 31 wt % is left in the retorted shale of the original 4.5 wt %. Sulfur found in the raw oil shale is unretorted for nitrogen and hydrogen sweeping gases. On the other hand, increasing particle size from 2 mm to 11 mm did not have any significant influence on the sulfur content of the produced shale oil.

Finding sustainable alternative energy resources and treating wastewater are the two most important issues that need to be solved. Microbial fuel cell (MFC) technology has demonstrated a tremendous potential in bioelectricity generation with wastewater treatment. Since wastewater can be used as a source of electrolyte for the MFC, the salient point of this study was to investigate the effect of pH on bioelectricity production using various biomass feed (wastewater and river water) as the anolyte in a dual-chambered MFC. Maximum extents of power density (1459.02 mW·m−2), current density (1288.9 mA·m−2), and voltage (1132 mV) were obtained at pH 8 by using Bhairab river water as a feedstock in the MFC. A substantial extent of chemical oxygen demand (COD) removal (94%) as well as coulombic efficiency (41.7%) was also achieved in the same chamber at pH 8. The overall performance of the MFC, in terms of bioelectricity generation, COD removal, and coulombic efficiency, indicates a plausible utilization of the MFC for wastewater treatment as well as bioelectricity production.
