Abstract:
The Cu-based eatalysts were prepared by coprecipitation methods, with Na,CO,as the preeipitantand with the solutions of mixed nitrates. The effeets of Cu/Zn/Al ratio ,aging time, ealeination temperature onthe catalyst performanee were investigated ,and the catalysts were studied by X-ray difraction ( XRD),themo.gravimetrie analysis( ’TC ). The optimum preparation parameters were obtained as follows : the eu loading was4096 ,the ratio of zn and Al was 2. 7: 1 ,the aging time was 2h ,the ealcination temperature was 450’℃ ,and un-der these conditions , the conversion of dimethyl adipate and the yield of 1, 6-hexanediol were 98. 46%6 and72.99% ,respectively.
