EXAMINATION OF EASTERN US OIL-SHALE BY-PRODUCTS AND THEIR MARKETS

Established and potential oil shale product and by-product markets are examined in an effort to identify components or process configurations that might improve process economics and to evaluate promising directions for future research. These include tract elements, sulfur, cement, asphalt, bricks, fixed gases, specialty carbon fibres, adsorbent carbons, chemicals and chemical feedstocks. Market evaluations for the most part are based on the yields of by-products expected from an eastern US oil shale using Kentort fluidized-bed technology in a 6800 t day(-1) plant. For certain value-added products such as specialty fibres and adsorbent carbons, the discussion is more general.
