Process for producing carbonized lignite by single-stage thermal reprocessing

Zpusob výroby spocívá v tom, že hnedé uhlí s obsahem uhlíku v sušine 60 až 75 % hmotnostních, prchavé horlaviny 40 až 60 % hmotnostních a dehtu 17,5 až 30 % hmotnostních je drcením a mletím upraveno na velikost zrna pod 0,25 mm, zvlhceno na obsah veškeré vody v rozmezí 10 až 25 % hmotnostních, homogenizovaná smes je vnesena do retorty a po zhutnení neprímo zahrívána do vnitrní teploty retorty 950 až 1300 .degree.C, na této teplote udržována po dobu 2 a více hodin. Produkt je z retorty vyjmut po ochlazení na povrchovou teplotu 400 .degree.C. The method for brown coal coke production is based on the fact that brown coal with carbon content in dry matter of 60 to 75% by weight, volatile matter 40 to 60% by weight and tar 17.5 to 30% by weight is by crushing and grinding modified to the grain-size of under 0.25 mm, moistened to the total water content ranging between 10 and 25% by weight; the homogenised mixture is placed in the retort, and after its compacting it is indirectly heated to the internal temperature of the retort between 950 to 1300°C and kept at this temperature for 2 hours or more. The product is subsequently removed from the retort after cooling to the surface temperature of 400°C.
