Preparation of a coal conversion systems technical data book. Project 8979 quarterly report, November 1, 1977--January 31, 1978
A formula for calculating the calorific value of coal from its composition that recently appeared in Coal Age has been found to be inferior to the one we recently developed. True densities of some low-rank coals and of chars prepared from them have been collected. True densities of the coals average about 0.04 g/cu cm higher than is found for higher rank coal of the same hydrogen content. A table of properties of pure chemical compounds (which are expected to be components of coal liquids) has been prepared for the Data Book. Real gas properties of benzene--compressibility factor, activity coefficient, and residual thermodynamic functions--are presented. Properties of four syncrudes--two from the COED Process and one each from the H-COAL and Synthoil Processes--are reported. Charts giving partial pressures of hydrogen sulfide and ammonia in the NH/sub 3/--H/sub 2/S--H/sub 2/O subsystem for temperatures between 100 and 160/sup 0/F at 20/sup 0/ intervals are presented. Vapor-liquid equilibrium data for several binary systems are given. The performance of coal-cleaning equipment has been reviewed. Potential synthetic sorbents for absorbing sulfur dioxide in fluidized-bed combustors have been reviewed and discussed. An attempt is made to correlate water produced by pyrolysis with the oxygen content of coal. Four correlations for bituminous and lignite coals are presented and discussed. We have evaluated six correlations for calculating pressure drop in horizontal, dilute-phase, gas-solids transport by comparison with the available experimental data. Experimental bulk fluid temperatures obtained in SRC preheater at Wilsonville, Ala., are compared with those calculated by the use of Sieder-Tate correlation for heat transfer.
