Large-scale experiment on hydrogenation of coal extracts (heavy-oil experiment). Report III (in German)

Technical Report ·
OSTI ID:7220550
Although the experiments reported here were carried out at 300 atm pressure, they were for the purpose of gaining information and experience to be used in a new 700 atm installation at Welheim (Bottrop). The things investigated included various catalysts in liquid or solid form, the possibilities of hydrogenating various products (pitch, tar, anthracene oil residue, etc.) besides coal extract, and attempts to increase yields of gasoline. The apparatus was essentially the same as in previous experiments except for the addition of some preheaters. Catalysts used included iron on coke and molybdenum on coke. (Molybdenum seemed better because it did not cause stoppages of tubing or great differences in pressure through the system. Gasoline yields ranged from about 10 percent to about 25 percent, depending on starting material, temperature drop between ovens, and processing time. The report included much data. One of the promising experimental variations was the placing of a separator between ovens 1 and 2, thus causing oven 1 to act more or less as a liquid phase, and oven 2 to act more or less as a vapor phase, with oven 2 using a solid catalyst (5058). This arrangement seemed to double gasoline production, giving a high-quality gasoline (high aromatic content, octane number 80 to 90 before refining) with markedly different characteristics from the gasoline produced by other variations investigated. 8 diagrams, 3 tables.
