Abstract
This invention generally relates to short residence time decomposition and volatilization of coal to produce liquid co-products while minimizing production of char and gas without utilization of external hydrogen, that is, hydrogen other than that contained in the coal feedstock. The invention more particularly relates to an improved method of economically producing uniform, fluidic, oil-type transportable fuel systems and fuel compositions and a slate of 'value-added' co-products by a coal refining process employing short residence time hydrodisproportionation (SRT-HDP).
