This report, which presents the results of a comprehensive survey with respect to thermal properties of coal, is part of a broader study which also includes oil shale, tar sands, and gas hydrates. This survey shows the need for experimental work on heat of combustion, heat capacity/enthal py , thermal conductivity, and heat of wetting for both wel 1-characterized premium coal samples and for samples of the type which will be used directly in conversion processes. Widely accepted, standardized measurement techniques do not exist for three of these properties (heat of combustion excepted) and must be developed; in addition, reliable data must be generated for efficient use of coal as a feedstock. Theoretical studies which will allow for modeling of properties should proceed along with the experimental investigations to allow for improvement in ability to predict coal properties for process design. Recommendations for work appropriate to the National Bureau of Standards and the justification for these recommendations are included.
