• 英文摘要： Quinoline poison inhibits the cumene cracking reactions over Mo-
  containing CaX zeolite at 450-550℃, and decreases the selectivity to dealkylation
  reaction. Contacting the catalysts to water vapor before the reaction increases
  increases the conversion and the selectivity to dealkylation reaction. These results
  suggest hydroxyl groups on zeolites are the active sites for cumene dealkylation.
  Mo in zeolite can enhance the catalytic activity for cumene dealkylation. The
  electrostatic field associated with Mo could increase the acidity of hydroxyl groups
  and thus, increases the activity for cumene dealkylation. The dehydrogenation of
  cumene, another part of cumene cracking reaction, might be catalyzed by the
  electrostatic field associated with Ca++ ions. It might also be a homogeneous
  reaction.
