In the Paraho Direct process, the crushed and screened raw oil shale is fed into the top of the retort through a rotating distributor. The oil shale descends the retort as a moving bed. [1] [14] The oil shale is heated by the rising combustion gases from the lower part of the retort and the kerogen in the shale decomposes at about 500 °C (932 ...
contact us· The measured crushed shale permeabilities display a dependency on all these parameters. However, the particle size and the pore pressure appear to be the more important factors. This makes the reported values strongly dependent on the exact measurement procedure. This study was complemented by the imaging of crushed shale samples with a micro ...
contact usThe ability to predict the quantity of oil retained on unretorted shale is necessary if viable models of the retorting process are to be formulated. A knowledge of the amount of retained oil is important because a portion of it may be cracked and thus increase the quantity of carbon residue found on the spent shale. Carbon residue not only provides a significant portion of the energy needed to ...
