Abstract
There is provided with a carbon dioxide treating method capable of suppressing a decrease in the content of a hydrocarbon contained in natural gas before and after removal of carbon dioxide. A method for treating carbon dioxide contained in natural gas comprises: preparing an aqueous dispersion containing magnesium hydroxide and acetonitrile; bringing the aqueous dispersion and the natural gas into contact with each other; and making the magnesium hydroxide and the carbon dioxide react with each other, wherein the aqueous dispersion further contains metal hydroxides, and the metal hydroxides include barium hydroxide, zinc hydroxide, sodium hydroxide, and calcium hydroxide.
