Grassl, G

The Puertollan coal was a young bituminous coal with 26.5% ash and was similar to Upper Silesian coal. In a laboratory test of ash removal, it was found unfavorable (in that there was a yield of 32% compared to 50% from the Silesian coal). More favorable data in decomposition and gasification were obtained from a hydrogenation test with the de-ashed coal than with the Silesian coal. On account of the mediocre results with de-ashing, the coal, which was not de-ashed, was extractively hydrogenated using 600 atm, a middle oil paste, and high-level charge at 435/sup 0/C. Thus, in addition to increases in splitting and gasification, the high ash content effected a sharp decline in asphalting in comparison to the Silesian coal containing 5% ash. Filterability of the product yielded was, at first, good, but filtration time required rose significantly more quickly than with Silesian coal. This was possibly caused by the higher level of solids. Three tables presented data on coal composition and hydrogenation results for Puertollan coal as compared to Silesian coal. 3 tables.
