In short tests, results of the effects of a bituminous coal addition to the processing of tar and pitch were obtainable. Coal used was that from the Heinitz Mines (Upper Silesian), saturated with 1--1.2% iron sulphate. On a mixture of bituminous coal tar residue and tar oil, with a relatively low level of solids and asphalt, a substitution was made for the addition of 2% alkalized iron-grude-catalyst with 20% coal. The same yield was reached using a straight-run procedure. The coal gave somewhat more gasification and additional asphalt in the sludge without increasing the solids content correspondingly. In spite of this, the carbonization results were somewhat improved, which led one to conclude that the coal addition fostered the decomposition of the tar asphalt, and, that the asphalt from the coal could be better carbonized than that out of the tar. One found, also, that the tar mixture with coal additive permitted trouble-free hydrogenation to gasoline and middle oil. Still another short test met with success. A bituminous coal tar pitch containing 24% benzene solids and 36% asphalt, which could not be processed with iron catalyst or even molybdenum-grude, was hydrogenated to gasoline and middle oil with a usable yield of .25 by a 20--25% addition of coal. Here too, the carbonization results were good. The addition of coal had no notable influence on the properties of the resulting oils. The document included test procedures. 11 tables.
