This report gave the results of an 11-hour experiment in a 100-liter oven with subsequent refining of the product. The beginning material, CV/sub 2/b gasoline from Scholven, was dehydrogenated and refined to a gasoline containing about 85% aromatics and containing about 10% to 15% more components boiling up to 100/sup 0/. The butane-free yield was about 85.2% when distilled to 165/sup 0/, and there was a distillation residue of 2%. The experimental conditions included the following: total pressure of 51 atm including hydrogen partial pressure of 24 atm; temperatures of 533/sup 0/ at oven entrance, 523/sup 0/ in the middle of the oven, and 301/sup 0/ in the refining oven; throughput of 0.48 kg/liter/hr; and gas volume of 0.92 cubic meters per kg of charge. The specific gravity of the product was about 0.822, the aniline point was -34/sup 0/, the iodine number was 1.7, and the octane numbers by the motor method were 92.5 before and 97 after addition of 0.12% tetraethyl lead. (The starting material had had measures of specific gravity 0.804, aniline point -7.50, iodine number 7.5, and aromatic content 52%). Later the product gasoline was used to form mixtures containing 50% aromatics with two other gasolines in turn, one a light gasoline from bituminous coal tar and the other VT705. Tables in the report gave test results of those mixtures, which showed excellent overload curves. 4 tables.
