blocked during the 1,2-DCE dehydrochlorination reaction and
indicating that the reason for inactivation should be acetylene
polymerization resulting in carbon deposition and pore block-
ing. It also can be seen that the surface of used catalyst was
partly covered aer the catalytic reaction, with the densication
of pores on the used catalyst because of the coke deposition, as
shown in Fig. 2b and d by SEM. Therefore, it can be explained
that the main reason for catalyst deactivation was that coke
deposition occurred in the dehydrochlorination of 1,2-DCE,
which blocks the active sites of the catalyst. Whereas it can be
found in Fig. 2a and c, the overall morphology of fresh and used
catalysts remained unchanged aer the catalytic reaction,
indicating that the catalysts had excellent structural stability.
