Abstract: A method for producing and separating high-purity oxygen and hydrogen from fossil fuel without emission of carbon dioxide is provided to minimize use of fossil fuel, produce high-purity oxygen and hydrogen, prevent air pollution by preventing carbon dioxide from emitting into the atmosphere, and minimize heat loss by performing all processes at high temperatures. A method for producing and separating high-purity oxygen and hydrogen from fossil fuel without emission of carbon dioxide comprises: a first step(S1) of reforming a fossil fuel by a steam reforming process, a partial oxidation process, or an automatic thermal process to prepare a mixed gas containing hydrogen, carbon dioxide, carbon monoxide, and water vapor; a second step(S2) of separating hydrogen from the mixed gas by using a hydrogen separation membrane to prepare a carbon dioxide-rich gas; a third step(S3) of separating oxygen from the carbon dioxide-rich gas by using an oxygen separation membrane to prepare a carbon monoxide-rich gas; and a fourth step(S4) of reacting the carbon monoxide-rich gas with water to prepare a residual gas having the same composition as the mixed gas prepared in the first step, wherein the steps(S1,S2,S3,S4) are circulated by supplying the residual gas prepared in the fourth step into the mixed gas of the second step.
