Abstract: In this paper, B-02 catalyst, developed by Yanshan Synthetic Rubber Factory and used in two large production plants, was investigated by means of pulse technique and temperature-programmed techniques, as well as XRD and FT-IR techniques. Three related iron compound, magnesium ferrite, hematite, and maghemite, were also studied.
XRD showed the presence of two crystallographic phases, viz., magnesium ferrite and hematite, in the B-02 catalyst.
A combination study of the reduction behavior of B-02 was established, comp...
