    摘要: The present invention relates to a catalyst for preparing synthesis gas from natural gas and carbon dioxide and a preparation method thereof. More specifically, the present invention relates to a method for preparing synthesis gas to use carbon dioxide economically, wherein the synthesis gas is suitable for methanol synthesis and can be used in Fischer-Tropsch synthesis by maintaining a specific ratio [H2/(2CO+3CO2)=0.85 ∼ 1.15] of carbon monoxide, carbon dioxide, and hydrogen through a mixed reforming reaction which causes a steam reforming reaction of natural gas and a carbon dioxide reforming reaction of methane at the same time. In addition, the present invention relates to: a catalyst for performing methanol synthesis or Fischer-Tropsch synthesis using synthesis gas which is prepared in the presence of a specific catalyst consisting of Ni/Ce/MgAlOx or Ni/Ce-Zr/MgAlOx; a preparation method thereof; and a method for preparing synthesis gas using the catalyst, which is suitable for methanol synthesis and can be used in Fischer-Tropsch synthesis. Accordingly, the catalyst according to the present invention suppresses the inactivation of a catalyst caused by cork generated during a reaction and also suppresses the inactivation of a catalyst caused by re-oxidation of nickel due to water added during a reaction. Therefore, the catalyst according to the present invention has excellent reactivity as compared with conventional catalysts for mixed reforming reactions.

    摘要: The present invention relates to a methanol synthesis method using a synthesis gas generated by a mixed reforming of natural gas and carbon dioxide. More particularly, the method of the present invention seeks to utilize carbon dioxide in an economically advantageous manner, and firstly produces a synthesis gas by using a catalyst (Ni/Ce/MgAlO x , or Ni/Ce-Zr/MgAlO x ) and a reaction process condition under which carbon monoxide, carbon dioxide, and hydrogen maintain a specific ratio [H 2 /(2CO+3CO 2 ) = 0.85-1.15] from the mixed reforming wherein the steam reforming of natural gas and the carbon dioxide reforming of methane are carried out at the same time. Subsequently, the thus-produced synthesis gas is employed to synthesize methanol using a catalyst system (the catalyst consisting of a Cu-Zn-Al-based oxide containing CuO, ZnO, and Al 2 O 3 at a predetermined ratio, and cerium-zirconium oxide produced by a sol-gel method) which is appropriate for a methanol synthesis while producing less by-products. Further, the present invention relates to a methanol synthesis method using carbon dioxide in which the synthesis gas which is the unreacted material remaining after the completion of said reforming, is efficiently recirculated and reused to improve the carbon use efficiency (methane and CO 2 use efficiency) of the whole process as well as energy efficiency.
