Abstract: The present invention relates to a method of selectively preparing ethanol using synthesis gas containing hydrogen, carbon monoxide, and carbon dioxide, comprising the steps of preparing dimethyl ether through hydrogenating the synthesis gas (step 1), preparing methyl acetate through a carboxylation reaction of the dimethyl ether in the presence of a ferrierite catalyst (step 2), preparing ethanol as a main product and acetic acid as a by-product by hydrogenating methyl acetate (step 3), and separating the main product of ethanol and the by-product at step 3, preparing methyl acetate through an esterification reaction of the separated by-product, acetic acid and methanol, and recycling the methyl acetate to step 3 (step 4). According to the present invention, a novel ferrierite catalyst is used as a catalyst, and a technique of layer inversion flowing layer is introduced to simplify reaction processes, thereby selectively proucing ethanol with high yield and enhancing carbon use efficiency. In addition, an alcohol fuel receiving spotlight as alternative energy resources according to the exhaustion of petroleum resources may be prepared by a catalytic, chemical and economic conversion method.
