    摘要: The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.

    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.
