The invention discloses a reforming catalyst for producing synthesis gas from methane and a preparing method thereof. The reforming catalyst is composed of Ni/Al2O3, SiC, Li/ZrO2 and activated carbon. Ni/Al2O3 is prepared through sintering and reduction of soluble nickel salt and Al2O3. Li/ZrO2 is prepared though roasting and reduction of soluble lithium salt and ZrO2. The raw materials are mixed in proportion for forming and pelleting, and then roasting is conducted to obtain the reforming catalyst. Compared with an ordinary Ni-based catalyst, the reforming catalyst has the advantages that catalytic reaction on CO2 reforming CH4 is remarkable and efficient, transformation efficiency is high, sintering and carbon depositing do not occur easily, catalysis activity and stability are high, using effect is good, and service life is long. 本发明公开了种用于甲烷生产合成气的重整催化剂及其制备方法，由Ni/AlO、SiC、Li/ZrO和活性炭组成，Ni/AlO由可溶性镍盐与AlO经烧结以及还原制备，Li/ZrO由可溶性锂盐与ZrO经焙烧及还原制得，将上述材料按照配比混合，成型造粒，焙烧处理即可。本发明催化剂较普通的Ni基催化剂，对CO重整CH反应起到明显高效的催化反应，转化效率高，而且不易烧
