The present paper presents batch autoclave data on the direct hydrocracking of a single sub-bituminous coal from the Powder River basin of southeastern Montana. Comparative data were also obtained with the Pittsburgh Seam bituminous coal that was used in the previous work (I). Data on the regeneration of simulated spent melts from such an operation are also given in a continuous bench-scale, fluidized-bed combustion unit. 

C for 4 hr before use. Sub-bituminoues coal from the Colstrip Mine in southeastern Montana was used in this work, and its analysis is given in Table I. The residence time at temperature was 60 min in all the runs reported here. 

Figure 4. Projection of sea level temperature changes (MAT and MART) from coastal to interior areas for two transects in the western United States. Transect A 1 = coastal California, 2 = southeastern California, 3 = northern Arizona Transect B 4 = coastal Washington, 5 = Washington, 6 = Idaho, 7 = central Montana. Points 1 and 4 represent actual values all other values are calculated from local lapse rates to 0 m. From Meyer (1992).
