Abstract

Abstract: In this article the dispersion of CuO,NiO on the HZSM-5 support was discussed bv XRDmethod;Spontaneous dispersion tendency of CuO is more obvious than that of NiO.Their dispersion degrees are different when proportions of CuO and NiO are different.In case where the proportion is 0.6423,the dispersion threshold is the largest. This threshold 1s 0.12 g CuO/g HZSM-5 which corresponds to the optimum proportion of CuO and NiO.when the catalyst is used to synthesize n-butylamine,

Key words: Dispersion threshold, Dispersion quantity, CuO, NiO, HZSM-5
