Disposal and uses of oil shale ash

This study was initiated to determine some to the properties of waste shale ash. General studies dealing with a variety of Piceance Creek shales retorted and burned for various times and temperatures were made. One objective of this approach was to define as nearly as possible the best conditions for precessing shale ash before it is dumped, in order to obtain a well stabilized dump least subject to wind and water erosion and land slides. The variables studied included composition of shale ash, burning temperature, burning time, moisture content, degree of compaction, storage time, and storage temperature.
