研究了几种活性分布对国产中变催化剂有效因子的影响。结果表明:在工业生产条件下,采用活性集中于表层的分布可以有效地提高中变催化剂的利用率.
The effect of several active distributions on the effective factor of home-made medium-change catalysts was studied. The results show that under the conditions of industrial production, the distribution of activity concentrated on the surface layer can effectively improve the utilization rate of the medium-change catalyst.
