An incremental model for coal evaluation—I. Liquefaction

Energy, 1987, vol. 12, issue 2, 137-145

Abstract: Because of differences in requirements for specific applications, coal values can vary greatly. We have devised a model to evaluate feedstock coals for hydrogenative liquefaction. In this method, incremental values are assigned to conventionally available quality parameters of coal based on stoichiometry, technology and general process economics. In addition, incremental values for variations in chemical reactivity, mechanical property and transportation cost were derived. These incremental values represent quantitative expressions for premium and discount of the coal with variations in quality. The relative values of coal may be calculated from these incremental values by using a simple procedure. The model provides a guide in technical and marketing studies.
