Abstract
In one aspect, a method for coal purification and gasification may include steps of heating the coal including various hydrocarbons and harmful substances such as sulfides, phosphates, etc. to 900 to 1200° C. in a coal gasifier; providing a reaction chamber with oxygen and connecting with the coal gasifier; the sulfides, phosphates, etc. in the gasified coal entering the reaction chamber from the coal gasifier and reacting with the oxygen therein; separating mixtures from the reaction chamber to collect hydrocarbons in its fluidized phase; heating the fluidized hydrocarbons; and providing oxygen to react with the gasified form of hydrocarbons to achieve a complete burning of the hydrocarbons.
