Progress in Catalytic Pyrolysis of Oil Shale

Abstract

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.

Gas Generation and Its Carbon Isotopic Composition during Pyrite-Catalyzed Pyrolysis of Shale with Different Maturities

“…Additionally, minerals enriched in shale, such as clays (e.g., kaolinite), carbonates (e.g., calcite) and pyrite, have been considered as geological catalysts due to their positive effects on hydrocarbon generation [24][25][26][27]. Kaolinite-type minerals were found to have low catalytic activities and to slightly increase CO 2 yields during kerogen pyrolysis [28].…”
