Review of Needs for Thermophysical Property Data on Solid Feedstocks. 2. Oil Shale

摘要

The report, a comprehensive survey concerning oil shale, is the second in a series dealing with needs, particularly for thermophysical properties, for solid fuels/feedstocks. The survey shows the need for experimental work on heat of combustion, heat of retorting, heat capacity/enthalpy, thermal conductivity, thermal expansion and heat of immersion for raw, spent and burnt shale, for kerogen and for the mineral matter found in shale. These studies should be preceded by agreement on the properties necessary for good characterization of the shale and on the methods of measuring these properties; the thermal properties measurements should be made on well-characterized samples. Standardized measurement techniques do not exist for thermal properties, with the possible exception of heat of combustion, and must be developed. Existing data must be evaluated and reliable data generated. Theoretical studies that will allow for modeling of thermal properties should proceed along with the experimental investigations to improve the ability to predict shale properties for process design. Recommendations for work appropriate to the National Bureau of Standards are included.
