Abstract NiAl2O4 supports and fresh and reactivated Ni/NiAl2O4 catalysts were tested in the gas phase hydrodechlorination of 1,2,4‐trichlorobenzene. Fresh catalysts hydrogenate 1,2,4‐trichlorobenzene to cyclohexane in the first 30 min of reaction at 523 K. An irreversible partial chlorination of the catalytic surface makes the hydrogenation of the aromatic ring difficult.
