Sažetak
The brown coal pyrolysis was estimated on pilot unit at 650°C to produce liquid product (organic and water parts). The mass balance of pyrolysis products and analysis of gas composition and liquids composition were carried out. The mass balance showed that the highest yield had coke (43 % wt.). The pyrolysis gas contained mostly methan, hydrogen and carbon oxides. The organic part was separated out of the liquid product by sedimentation. Water part contained mostly oxygen organic compounds like phenols and carboxylic acids. Organic part contained mostly aliphatic hydrocarbons, mono and polycyclic aromatic hydrocarbons. The content of oxygen in organic part of liquid pyrolysis product was rather high and therefore the subsequent treatment of this product is necessary to produce liquid fuels.
