Pyrolysis provides an efficient way to use coal volatiles, the inherent gas, liquid and structured chemicals containing in coal. For 100 years the scientists and engineers worldwide in the area have worked on understanding coal pyrolysis and developing the technical processes that can run steadily in commercial scale to produce liquid tar with high yield and low contents of dust (e. g. , <0. 5 wt. %) and heavy components (e. g. , <30 wt. %). Although lots of pilot verifications and industrial demonstrations have been performed, there is unfortunately not such a kind of pyrolysis technologies commercially available, especially for treating small-size powder coal.
