METHOD FOR PRODUCING CLEAN ENERGY FROM COAL

摘要

A method for producing clean energy from coal by feeding the coal in a reactor (10) which is sealed to atmosphere and moving the coal in the reactor (10) while injecting oxygen (40) to combust a portion of the coal to yield a pressurized hydrogen rich raw gas and hot char. Said hydrogen rich gas is cracked in cracking compartment (21) to remove distillates and hydrocarbons and desulfurized to produce synthesis gas. The hot char is gasified in an air blown gasifier (11) to produce a fuel gas and a molten slag which are jointly directed out of the gasifier through a common port (23). The fuel gas and the molten slag are separated in a separator (24). After separation the fuel gas is desulfurized to produce gas which will produce very low Nox emission while combusted.
