Treated oil shale ash and its capacity to remove Cd and Pb from aqueous solutions [PDF]
Oil Shale, 2022 Cadmium (Cd) is the most highly toxic heavy metal even at a trace level. In this study, the oil shale ash treated material was used as an adsorbent to remove cadmium and lead (Pb) metals/ions from aqueous solutions.

Determination of some physico-thermal and mechanical characteristics of hydrated Jordanian Lajjun oil shale ash [PDF]
Oil Shale, 2023 The hydration of oil shale ash at different water-to-ash weight (W/A) ratios ranging from 0.4 to 0.8 was experimentally investigated. The ash hydrateâs physical characteristics, its particlesâ elemental composition, and the existing crystalline ...

Pore and fracture scale characterization of oil shale at different microwave temperatures [PDF]
Oil Shale, 2023 The spatial complexity of oil shale systems is manifested by microstructure, pore space randomness and extensive heterogeneity. A microwave pyrolysis device developed for this study was used to pyrolyze oil shale, and the microstructure before and after ...

Oil shale, shale oil, shale gas and non-conventional hydrocarbons [PDF]
EPJ Web of Conferences, 2015 In recent years there has been a world “revolution” in the field of unconventional hydrocarbon reserves, which goes by the name of “shale gas”, gas contained inside clay sediments micropores. Shale gas finds particular development in the United States, which are now independent of imports and see a price reduction to less than one third of that in ...

Long-term stability of pillars in an underground oil shale mine [PDF]
Oil Shale, 2022 A method was developed to predict the collapse of underground rooms in a previously mined area. This methodology is necessary to assess the condition of the excavated areas in the case of an additional load of buildings and supporting pillars weakening ...

Three-dimensional molecular modeling of Dachengzi oil shale kerogen [PDF]
Oil Shale, 2022 A three-dimensional (3D) molecular model of Dachengzi oil shale kerogen was constructed using quantitative 13C direct polarization/magic angle spinning solid-state nuclear magnetic resonance (DP/MAS SSNMR) data and accurate quantum chemistry methods. The
