NOVELTY - Hydrogen and oil are produced by mixing obtained hydrogen and carbon dioxide in the presence of catalyst to produce fuel oil; transforming carbon dioxide by increasing the transformation ratio using the upper limit of operation temperature, cooling and removing the water vapor, discharging the generated gas, and continuously enforcing the carbon dioxide transformation while regulating the components of aeration product; and separating and refining obtain product to generate finished product fuel oil.    USE - Method of producing hydrogen and oil (claimed).    ADVANTAGE - The method reduces production cost by greater than or equal to 30%, and solves energy shortage.    DETAILED DESCRIPTION - Hydrogen and oil are produced by:    (A) producing vapor using a solar thermal collector (12), using a vapor feeding tank for storage, and leading the vapor output from the vapor tank (13) to an evaporator (5) from a middle gas inlet;    (B) heating potassium iodide and potassium iodate solution to form condensing water which flow out from a lower water outlet of evaporator and returns through a water inlet of solar thermal collector, or leading the vapor output from the vapor tank to enter a calcinatory (2) and to the evaporator heating;    (C) adding iodine and potassium hydroxide in a closed corrosion proof salt producing drum (1) in a production starting stage, and adding distilled water using a water tank;    (D) stirring at room temperature to generate potassium iodide and potassium iodate stored in a liquid tank, and separating suspension flowing out from a bottom liquid outlet of evaporator by a corrosion proof centrifuge to separate potassium iodide and potassium iodate solids;    (E) calcining separated potassium iodide and potassium iodate at 100-250 degrees C, and feeding potassium iodide to a desalting drum to merge with potassium iodide solution and water flowing out from an evaporator;    (F) transporting potassium iodide solution to an electrical field resolver to recycle oxygen generated by calcining;    (G) discharging purified oxygen from a top gas outlet of absorbing tower, leading to an oxygen gas tank for storage, and hydrolyzing potassium iodide solution to obtain hydroiodic acid;    (H) leading distilled water to electric resolver and performing hydrolysis under the actions of two positive and negative electrical fields of the electric resolver to generate hydrogen iodide solution and potassium hydroxide solution;    (I) leading generated hydrogen iodide solution to a photolysis pond to generate hydrogen and recycling iodine, discharging water from lower outlet, and discharging gas and liquid from the outlets of the photolysis pond;    (J) leading the potassium iodide solution from desalting drum to enter the photolysis pond from the bottom liquid inlet to generate potassium triodide solution;    (K) controlling the photolysis of hydrogen iodide solution and recycling of iodine;    (L) leading water to evaporator, heating the water to generate vapor, discharging the vapor to a condenser to be used for preheating the solution of potassium iodide and potassium triodide, condensing the vapor into distilled water and leading to water tank, feeding the distilled water in water tank to salt producing drum, and discharging impurity in water from bottom water outlet of evaporator;    (M) mixing obtained hydrogen and carbon dioxide in the presence of catalyst to produce fuel oil;    (N) transforming carbon dioxide by increasing the transformation ratio using an absorber and the upper limit of operation temperature, cooling and removing the water vapor, discharging the generated gas, and continuously enforcing the carbon dioxide transformation while regulating the components of aeration product; and    (O) separating and product refining to generate finished product fuel oil.
