Chemicals from coal. Interim report for HRI H-Coal
Results of an investigation to determine the suitability of the HRI H-Coal Syncrude as a petrochemical feedstock are reported. A sample of the whole crude was distilled into four straight run fractions; IBP-350/sup 0/F naphtha, 350-550/sup 0/F mid-distillate, 450-800/sup 0/F vacuum gas oil, and 850-FBP/sup 0/F resid. Laboratory studies in metal reactors and computer and mathematical simulations were performed to provide overall material balance data for a conceptual plant. The naphtha was subjected to hydrotreating and reforming studies. The mid-distillate was hydrocracked to produce more naphtha which was further processed by hydrotreating and reforming. The vacuum gas oil was hydrocracked to produce more hydrocrackate naphtha which was mathematically hydrotreated and reformed. Steam coil cracking of the various naphtha and mid-distillate fractions was also performed to evaluate their potential as feedstocks for direct olefin production. None of the fractions surveyed was very attractive as an ethylene cracker feed. The reformate from each of the three distillates was then mathematically hydrodealkylated so that each fraction was converted to a product slate consisting of methane, LPG's, benzene, and fuel, along with the total hydrogen consumed. The value of the products obtained per 100 pounds of each distillate was $10.06, $8.12, and $6.91 for the naphtha, mid-distillate, and vacuum gas oil respectively. Based on these values, and the difficulties encountered in recovering the gas oil, it was concluded to be economically unattractive as a petrochemical feedstock. The high aromatic yield obtained from the straight run and hydrocrackate naphthas, however, make these fractions very attractive as petrochemical feedstocks.
