Processing of heavy oil vacuum distillate from the skimmer at 600 atm using a fixed arrangement of the Catalyst (Kontakt) 8376 to diesel oil with a low solidification point (in German)
Dr. Grassl summarized his experimentation by pointing out the doubled yield obtained by hydrocracking of 85% vacuum distillate as compared to the original heavy oil from the skimmer (hot catch pot). The vacuum distillate of the skimmer heavy oil from Ka804 (Catalyst) obtained from Silesian coal was processed into diesel-oil using Tungsten Kontakt 8376 with a throughput of .6 to 1.0 and no loss of Kontakt. During the same series approximately 60% diesel-oil with cetane number 45 and a solidification point under -60/sup 0/C at 6.2% gasification was obtained using injection. At a .8 throughput and 434 to 460/sup 0/C the yield obtained up to 330/sup 0/ amounted to approximately .50. A 10 kg sample of the described diesel-oil with the characteristics listed in the chart was sent to the Reichsforschungsministerium for inspection. Dr. Grassl noted that by recycling the constituents over 330/sup 0/, the yield decreased while the cetane number was slightly improved. The gasification dropped to 2.4%, whereas the solidification point remained unchanged. Raising the temperature to 450 to 468/sup 0/ and the throughput to 1.0 resulted in cracking improvements but also caused the optimum of hydrogenation to be exceeded which was noticeable by the beginning precipitation of coronene. 1 table, 1 chart.
