The Disposal and Environmental Effects of Carbonaceous Solid Wastes from Commercial Oil Shale Operations.

摘要

The major by-products from oil shale retorting are the solid spent shale,the process water generated during pyrolysis and process gases. Studies carried out in the past show that chronic exposure to inorganic and organic carcinogenic trace substances can have a detrimental effect on ecology. The potential impact from trace organic matter from carbonaceous spent shale has not been investigated to date. The main objective of the present program is to fill this gap. Samples of soil,water,vegetation,and air from various pristine areas of potential oil shale operations were collected and analyzed for their polycyclic organic matter content. Samples of carbonaceous spent shale from retorting in pilot plants were also analyzed for polycondensed aromatic compounds. This was done to establish a base line for future comparative studies.
