The combination of steam and CO 2 reforming of bio‐oil is proposed in this article. The combined reforming can make good use of the advantages of steam reforming and CO 2 reforming. The results indicate that H 2 yield, potential H 2 yield, and H 2 /CO were 60.23, 81.97, and 2.77%, respectively, at the condition of 700°C and bio‐oil:CO 2 :H 2 O = 1:0.5:1.5. Bio‐oil:CO 2 :H 2 O has a significant effect on the H 2 yield, potential H 2 yield, and H 2 /CO in the process of combined reforming. A different ratio of H 2 /CO can be obtained by adjusting the proportion of bio‐oil:CO 2 :H 2 O, which can meet different industry requirements. The results of X‐ray diffraction and scanning electron microscope analyses indicate that the catalyst deactivation was the result of a combination of carbon deposition and Ni grain sintering, and the carbon deposition was a main reason for the catalyst deactivation.
