摘要： Upgrading coke quality of coals by adding a pitch-like product with a softening point (K-S) of 90.degree.-160.degree. C. to the coal. The additive is obtained by treating finely divided coal or other carbon containing raw material with hydrocarbon solvents derived from coal and petroleum and then removing 2-20% of the light boiling components of the highly aromatic pitch-like product.

摘要： A process is described for bringing ground coal or similar carbon-containing raw materials into solution with aromatic solvents under elevated pressure and at elevated temperature. The solvents used are high-aromatic residues obtained from the pyrolysis of petroleum fractions, having an average boiling point of above 380.degree. C., and/or high-aromatic distillates from the pressure/heat treatment of coal tar pitch, having an average boiling point of above 380.degree. C., as well as from 5 to 30% of aromatic products or mixtures of aromatic products, having a boiling point of below 250.degree. C.

摘要： Contrary to known alkylation of pitches, it is disclosed that pitches are modified with particular aromatically substituted and activated C.sub.1 to C.sub.4 alkyl groups. The resulting modified pitches are easily polycondensed and give high coking residues and good mesophase formation. This is achieved on the one hand by dispensing with catalysts, which can be only incompletely removed from the pitch and, on the other hand, by employing reactive short chain alkyl aromatic compounds.
摘要翻译： 与已知的间距烷基化相反，公开了用特定芳香取代和活化的C1至C4烷基修饰间距。 所得改性沥青容易缩聚并提供高焦化残留物和良好的中间相形成。 这一方面通过分配催化剂实现，催化剂可以仅从沥青中不完全去除，另一方面通过使用反应性短链烷基芳族化合物。

摘要： Coal tar oil is separated quantitatively into neutral oil, phenols and bases by a two stage extraction with overcritical gases. Carbon dioxide is employed as an overcritical extraction agent, and propane or butane are preferably added as entrainers. The neutral oil is obtained in the first stage. Tar bases can be employed as an additional entrainer for improving the selectivity. The bases are extracted in the second stage. The method is associated with the advantage that it saves energy and that no byproducts are generated.
