The invention discloses an application of a layered loading catalyst in preparation of a lower alcohol by using a synthesis gas. The synthesis gas is transformed into CO2, water, methanol, C2+alchohol, other unsaturated organic oxygen containing compounds (for example, carboxylic acid, aldehyde, ketone, ester) and hydrocarbon byproducts by means of combination of an upper layer loaded Cu-Fe-Co base modified F-T synthetic catalyst CuaFebCocMd/SiO2 and a lower layer loaded Cu/ZnO/Al2O3/MxOy modified methanol synthetic catalyst, an obtained product and the incompletely reacted synthesis gas enter the lower layer catalyst, a part of the CO2 and the unsaturated organic oxygen containing compounds form alcohols by hydrogenation, and water is removed by a water gas shift reaction so as to promote the transformation of the byproducts in the synthesis process of the lower alcohol and effectively improve the reaction activity and the yield and selectivity of the lower alcohol.
