The unreacted aromatic oils separated from the reaction mixtures exhibited better color stability in comparison with the catalytic cracking heavyaromatics.
与催化裂化重质芳烃原料相比，未反应芳烃油显示了较好的安定性。

The catalysts exhibited even better catalytic properties when Zn loadings were 2.0wt%. Increase in Pt content had remarkable inhibition on formation of heavyaromatics.
当催化剂中锌质量分数为2．0％时，表现出更好的催化性能，铂的增加对重芳烃的产生具有明显的抑制作用。
