Distillates, hydrotreated coal derived

Many of the Southwest states have a large number of gas fired boilers. These units were very low in original investment cost and their continued utilization concerns utilities in those areas. Hydrotreated coal derived distillates offer a means of keeping these units available for years of additional service. 

Caldwell and Eyerman ( 6) hydrotreated and hydrocracked several coal-derived distillates and naphthas, including those from H-Coal, and evaluated these oils as potential petrochemical feedstocks. High yields of aromatics were obtained upon reforming. 

For jet fuels, a visual rating of No. 1 or No. 2 is required at 260°C in the jet fuel thermal oxidation stability test (JFTOT-ASTM D 3241). Also, a pressure drop of less than 25 mm Hg is required in this test, As shown in Table XI, the 250°F+ product from hydrotreated Illinois H-Coal syncrude passes both parts of the JFTOT test, even when the jet fuel is not refined enough to pass three other specifications aromatic content, smoke point, and gum content. When jet fuels are prepared from coal-derived syncrudes, the smoke point appears to be the limiting specification. The gum content and end point specifications are met when the jet fuels are distilled at 600°F. 

Coal liquids need to be refined to finished products such as jet fuels and diesel by hydrotreating and hydrocracking. Before GC-MS analysis of coal-derived JP-8 fuels, these fuels were first tested by separation into five distillate fractions using a fractional distillation apparatus. Table 32.9 lists the yields and boiling range of fractional distillation [33].
