Methanol synthesis method using synthesis gas generated by a mixed reforming of natural gas and carbon dioxide |
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/MgAlOor <sub/>Ni/Ce-Zr/MgAlO) and a reaction process condition under which carbon monoxide, carbon dioxide, and hydrogen maintain a specific ratio [H/(2CO+3CO) = 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 AlO 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 use efficiency) of the whole process as well as energy efficiency. |
