This translation was apparently of the record of a discussion between representatives of I.G. Farbenindustrie A.G. and Ruhroel GmbH about the relative merits of their particular vapor-phase processes. The I.G. used a three-step process of prehydrogenation, splitting, and dehydrogenation at 300 atm or less pressure, whereas Ruhroel used a one-step aromatization process at 700 atm (really 630 atm total pressure with 450 atm hydrogen partial pressure). The experiments reported by Ruhroel operated on coal-tar middle oils, whereas most of the I.G.'s work had been done on coal-liquefaction middle oil. It was mentioned that tar middle oils gave higher yields of gasoline and lower losses to gas formation during the vapor-phase processing, but significantly less liquid-phase gasoline and significantly smaller percentage of isobutane in the total butane fraction of the vapor phase. The report gave details of the experiments at Ruhroel and some comparative details from Ludwigshafen. It mentioned that a further series of experiments was planned, using both processes on the same coal-liquefaction middle oil, so that the two processes could be more directly and accurately compared.
