Abstract: A method for regenerating an amine-based, acid gas absorbent using a mixed catalyst containing silver oxide and silver carbonate includes the steps of absorbing an acid gas into an acid gas absorbent having an amine group to obtain an acid gas-absorbed absorbent; and regenerating the amine-based, acid gas absorbent by adding a catalyst mixture containing silver oxide and silver carbonate to the acid gas-absorbed absorbent and by removing the acid gas at a temperature ranging from 40° C. to 86° C. When the amine-based acid gas absorbent is an acid gas absorbent solution and when the acid gas that is absorbed into the acid gas absorbent solution is carbon dioxide, the catalyst mixture efficiently promotes decomposition of carbon dioxide-bound carbamate in the acid gas absorbent solution that absorbs the carbon dioxide through a novel catalytic reaction pathway.

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.
