Abstract: In the dehydrogenation of o-ethylaniline to indole, copper aluminum borate catalyst was easy to be deactivated by the carbon deposition and reduction of CuO. Cerium promoter was added to improve the reduction-resistant of this catalyst. Through the characterization of BET, XRD, H₂-TPR, XPS, it was found that the addition of cerium promoters did not change the structure of the catalyst, but significantly increased the capability of the anti-reductive. In the condition of which WHSV was 075 h^-1 and mole ratio of water and o-ethylaniline was 6:1, the conversion of o-ethylaniline and selection of indole were about 76.41 % and 77.27 %on the copper aluminum borate with 2%Ce,  while on the catalyst without Ce, the result were 64.6% and 70.8%.

Key words: Indole; Copper aluminum borate; Cerium promoter; Anti-reductive
