| Abstract: | The present invention relates to a method in which a catalytic reaction is used in order to produce hydrocarbons from renewable starting material derived from biological organisms such as vegetable lipids, animal lipids, and lipids extracted from macroalgae and microalgae, and more specifically relates to a method for selectively making a hydrocarbon, which is suitable for making gasoline or diesel, by removing the oxygen contained in the starting material without consuming hydrogen. In the present invention, the production takes place by bringing the starting material into contact with hydrotalcite, which constitutes a catalyst, thereby removing oxygen via a decarboxylation or decarbonylation reaction; and the starting material is one or more such material selected from triglycerides, fatty acids, and fatty acid derivatives obtained from a renewable source of supply originating from a biological organism. |

| Claim: | 1. A method of producing hydrocarbons using lipids derived from biological organisms and hydrotalcite, comprising the step of: pretreating hydrotalcite by heating the hydrotalcite to a temperature of 100-600° C. while blowing argon, nitrogen, oxygen or air to the hydrotalcite to remove moisture from the hydrotalcite, wherein the pretreated hydrotalcite is a double layered hydroxide including 50˜80 wt % of magnesium oxide and a residue of aluminum oxide, excluding moisture and anions, bringing a raw material into contact with the pretreated hydrotalcite as a catalyst to remove oxygen from the raw material by a decarboxylation or decarbonylation reaction, wherein the step of bringing the raw material into contact with the catalyst is carried out at a temperature of 200˜450° C. and a pressure of 0.1˜15 MPa, wherein the raw material is one or more selected from triglycerides, fatty acids, and fatty acid derivatives, which are obtained from renewable raw material sources derived from biological organisms, and wherein the product produced by the method comprises hydrocarbons. |
| Claim: | 2. The method of claim 1 , wherein the pretreated hydrotalcite is obtained by pretreating hydrotalcite represented by Chemical Formula I below: [X 2+ 1—n Y 3+n (OH) 2 ] b+ [A c— b/c ]·mH 2 O [Chemical Formula I] wherein X is a monovalent or divalent metal cation selected from the group consisting of magnesium, calcium, zinc, manganese, nickel, cobalt, strontium, barium, copper, lithium, sodium, and iron; Y is a trivalent metal cation selected from the group consisting of aluminum, indium, gallium, iron, cobalt, nickel, chromium, boron, lanthanum, and cerium; A is an anion selected from the group consisting of O 3 , NO 3 , SO 4 , CI, OH, Cr, I, SiO 3 , HPO 3 , MnO 4 , HGaO 3 , HVO 4 , CIO 4 , and BO 3 ; b is determined by n and the valences of X and Y; c is 1, 2, or 3; m is 0 to 4; and n is 0.2 to 0.33. |
| Claim: | 3. The method of claim 1 , wherein the raw material is obtained from: lipids derived from one or more selected from the group consisting of plants, animals, fish, macroalgae, and microalgae; recycled lipids from the food industry; or mixtures thereof. |
| Claim: | 4. The method of claim 3 , wherein the raw material is obtained from one or more selected from the group consisting of colza oil, rapeseed oil, palm oil, olive oil, sunflower oil, canola oil, bean oil, coconut oil, Jatropha oil, tall oil, lard, fish oil, milk fat, milk, microalgae, and macro algae. |
