Abstract
This invention generally relates to refining coal by fluidized hydrocracking employing short residence time volatilization and decomposition of the coal feedstock, with subsequent selective condensation and hydrostabilization without utilization of external hydrogen, that is, hydrogen other than that contained in the coal feedstock, to maximize oil yield and minimize char and gas production. 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).
