This invention generally relates to a catalyzed 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 catalyzed coal refining process employing short residence time hydrodisproportionation (SRT-HDP). The preferred catalysts are oxides and salts of iron.

An improved catalytic method for refining a volatile containing carbonaceous material, which method comprises the steps of: (a) heating a particulate, volatile containing carbonaceous material in the presence of a catalyst selected from the group consisting of iron-based, zinc-based, potassium-based, sodium-based, and calcium-based catalysts at a heat rate sufficient to maximize decomposition and minimize formation of char and condensation products to a volatilization temperature effective to produce a substantially decomposed volatilization product; and (b) contacting said substantially decomposed volatilization product with a hydrogen donor-rich gaseous atmosphere at a hydrogenation temperature effective to minimize formation of condensation products and reduce thermal cracking for a hydrogenation residence time effective to produce a hydrogenated volatilization product.
