        Abstract:

        Compared with the traditional process, the preparation of caprolactam by butadiene has the green, economical and environmentally friendly characteristics in which the partial hydrogenation of adiponitrile (ADN) to produce 6-aminohexonitrile (ACN) is the core step of the process. Ni/CaO ADN Ni-Fe/CaO catalysts were prepared by the deposition-precipitation method using urea as precipitant ADN applied to the partial hydrogenation of adiponitrileto prepare 6-aminohexanenitrile. XRD showed that FeNi3 alloy phase was formed in the catalyst after Fe doped, and TEM showed that the metal Ni became more dispersed after Fe doped. The effect of reaction temperature ADN reaction pressure on the hydrogenation performance of ADN was investigated. The experimental results showed that the ADN conversion was 87.5% and the ACN selectivity was 74.4% under mild conditions of 80 ℃, 4 MPa and 0.1 g of catalyst for 2h. ADN it was found that the catalyst could be regenerated after hydrogen reduction.
