Aromatization of middle oils of coal--oil slurry (in German)

Technical Report ·
OSTI ID:7320659
For the production of high-performance gasoline from liquefied coal there were various processes, chiefly aromatization (using various catalysts, reaction conditions, and pressures) and the DHD process in various combinations. This report gave rather extensive data on experiments with aromatization carried out at the I.G. Farbenindustrie. Two sets of experiments were run, one in a 2 liter oven and one in a 0.2 liter oven. Each set consisted of runs with two different starting materials: coal middle oils (from Scholven) both with and without raw gasoline content. Some runs in the 2 liter oven used a throughput of 1.5 kg/l/hr and others used 1.1 kg/l/hr, but all runs in the 0.2 liter oven used 1.0 kg/l/hr. At throughputs of 1.5, yields of gasoline with distillation cutoff 165/sup 0/C were in the range of 0.56 to 0.59 kg/l/hr for both types of starting material, whereas at 1.1, yields were in the range of 0.40 to 0.44 kg/l/hr. In the 0.2 liter oven at throughput 1.0, yields ranged from 0.31 (at 450 atm) to 0.50 (at 600 atm). Pressures used in the experiment varied from 450 atm to 600 atm, and temperatures varied from 25.0 to 26.5 mV. Although the variation was slight in most cases, yields seemed to increase a bit at lower temperatures and higher pressures. Also, the 2 liter oven seemed to give considerably better yields than the 0.2 liter oven. Gasolines produced in the experiments had octane numbers ranging from 88.5 to 92.0 after addition of 0.12 Pb.
