ABSTRACT Oil shale is an organic-rich, fine-grained sedimentary rock, containing kerogen, from which liquid hydrocarbons (called shale oil) can be produced. The oil shale deposits in the Tigray region are found in the northern parts of Ethiopia, Eastern Africa. They are of Upper Paleozoic in age, existing as remnants of the Cretaceous erosion period, underlain by tillites and overlain by sandstones. They were formed during the glacial retreat followed by marine deposition of shales in a basin…

Production of Isotropic Coke from Shale Tar at Various Parameters of the Delayed Coking Process

TLDR
To assess the quality of the resulting coke, properties such as the absolute density, yield of volatile substances, ash content, and total porosity were analyzed and the scanning electron microscopy technique was used to confirm the results of the analysis of the formed structure of shale coke obtained earlier.
