Low-Temperature Lignite Tar: Processing and Utilization.

Abstract The report concerns the composition and value of tars from low-temperature carbonization of coal. Low-temperature carbonization of coal offers promise as a means for obtaining char, a coke-like material that is potentially useful as a fuel, a source of carbon for the production of synthesis gas, and for blending with other coals to make metallurgical coke. Discussed is the production of acids, neutral oils, and pitch by distillation of low-temperature lignite tar. Aromatic and naphthene fractions of the neutral oil were converted into phythalic and maleic anhydrides. Paraffins and n-olefins were processed into alkybenzene sulfonate. Aromatic materials produced jet fuel. The pitch was processed to make it suitable for similar applications as high-temperature tar pitch, including preparation of carbon black and metallurgical electrodes.
