Disclosed are a low-temperature de-NOcatalyst using a ceria-alumina complex support, and a method of manufacturing the same. According to the present invention, provided is a low-temperature de-NOcatalyst using a ceria-alumina complex support, manufactured by impregnating noble metal and metal oxides into a ceria-alumina complex support synthesized by treating a ceria precursor and an alumina precursor in a predetermined mass ratio by a co-precipitation method.

Low-temperature de-NOcatalyst using ceria-alumina complex support and manufacturing method thereof

The present invention relates to an apparatus that produces a high-purity gas of producing a high-purity gas using the apparatus. An apparatus for producing a high-purity gas according to an embodiment of the invention may include a column configured to perform a sorption-enhanced reaction for removing a reaction by-product produced through a catalyst reaction by using sorption, wherein the column is divided into a plurality of sections, and the plurality of sections have decreasing proportions of a catalyst and increasing proportions of an adsorbent from a front end towards a rear end along a reaction path, and wherein the sorption-enhanced reaction is a sorption-enhanced steam methane reforming (SE-SMR) reaction for producing hydrogen by a methane reforming reaction and removing a by-product of carbon dioxide. According to an embodiment of the invention, a multi-section column may be applied to obtain an increased amount of gas production compared with the conventional sorption-enhanced reaction, even with the same amounts of catalyst and adsorbent.
