Winkler, K

The operation discussed was conducted at 630 atm total pressure, corresponding to 450 atm hydrogen pressure, with a production of 0.4 kg gasoline per liter of catalyst per hour. The losses of middle oil used were 12.2% to 12.4%. Added to this was the stabilization in Scholven with a gas loss of 3.5% to 5.0%. The gasoline had to be refined with sulfuric acid and redistilled. Total carbon gasification calculated to gasoline plus gasification was 17.6% to 19%. Furthermore, 100 parts middle oil gave about 87 parts high compression gasoline and, out of this, 82 parts refined stabilized gasoline, which led to a production factor of 1.22. Substitution of coal liquefaction products for the tar middle oil would reduce the yield by about 3% because of the lower carbon content of the middle oil. With coal liquefaction middle oil, the yield would be further reduced because a higher gasification of the coal liquefaction middle oil had to be taken into consideration if the same percent aromatics was desired from coas as from middle oil. With the same operating conditions, the gasoline from the liquefaction middle oil would have an octane number lower by 2 to 3 units than from tar middle oil. Liquid-phase production was greater at lower than at higher pressures. This was attributed to the difference in the H/sub 2/S content of the circulation gas.
