Supercritical Hydrotreatment of Arabian Topped Crude. A series of experiments were performed with Arabian topped crude (650F+) to investigate the hydrotreatment of high sulfur crudes in the presence of a light solvent under supercritical conditions. The experimental results obtained are summarized in Table IV. The overall results are comparable to those obtained from the supercritical hydrotreatment of SCE shale oil (Run l). The sulfur removal is very extensive (about 99 removal, reduced from 3.355 to 0.02 ). The nitrogen content in the heavy oil fractions are relatively low, less than 60 ppm for runs with total liquid hourly space velocity (LHSV) of 0.5 (Runs 6 and 7) and about 770 ppm for Run 8 with an LHSV of 1.6. Thus, for extensive nitrogen removal, lower LHSV is needed.
