Abstract: A method for producing clean energy from coal by feeding the coal in a reactor which is sealed to the atmosphere and moving the coal in the reactor while injecting oxygen to combust a portion of the coal in a substoichiometric mode to devolatilize the coal and yield a pressurized hydrogen rich raw gas which contains coal-derived cancer causing distillates and hydrocarbons together with a hot char. The distillates and the hydrocarbons are cracked to result in a cracked gas of essentially 2H2 and 1CO which after desulfurization becomes an ideal synthesis gas that can be synthesized to a liquid fuel for heating and transportation as an alternate to petroleum. The hot char is gasified in an air blown gasifier to produce a fuel gas and a molten slag which are jointly directed out of the gasifier through a common port which is maintained open for the free flow of both.
