The acidities of HZSM-5/Al_2O_3,zeolites modified with P or P/Mg have been investigated by means of thermogravimetry of NH_3 and pyridine.4-methyl- quinoline poisoning methods.It was observed that strong acidity centers of ZSM-5 zeolite catalysts were greatly decreased after loaded with P or P/Mg but weak acidity centers were more or less unchanged.The acidity distribution of P/Mg modified ZSM-5 zeolites had a greater change than that of P modified ZSM-5.As the modifier occupied a part of the zeolites...

The acidities of HZSM-5/Al_2O_3,zeolites modified with P or P/Mg have been investigated by means of thermogravimetry of NH_3 and pyridine.4-methyl- quinoline poisoning methods.It was observed that strong acidity centers of ZSM-5 zeolite catalysts were greatly decreased after loaded with P or P/Mg but weak acidity centers were more or less unchanged.The acidity distribution of P/Mg modified ZSM-5 zeolites had a greater change than that of P modified ZSM-5.As the modifier occupied a part of the zeolites surface,filling partly the pore opennings,the pore size was thus changed and displaced some strong acid sites at the pore opennings.A part of P or P/Mg entered into the chan- nels of the zeolite,changed the winding of channels and occupied the strong acidity center of inner channels.All of these tend to decrease the toluene eth- ylation activity,to inhibit the isomerization reaction and,as a consequence, raising the pare-selectivity to a value greater than 97%.

用氨的热失重及吡啶的中毒实验研究了 PHZSM-5/Al_2O_3及 PMgHZSM-5/Al_1O_3沸石催化剂的酸性,发现改性后的 HZSM-5型催化剂的强酸中心减弱,弱酸中心变化不大,并且经 P、Mg 改性后的酸分布变化比 P 改性后要明显,实验结果说明这主要是由于 P 或 P、Mg 进入了沸石的孔道内,并占据孔口的强酸中心部位以及发生孔口部分阻塞的缘故,这一效应抑制了对-甲乙苯异构化反应,从而提高了甲苯乙基化的对位选择性.

In this paper , the effects of modifiers on homogeneous hydrogenation catalysts of benzene have been shown. The water increases the activity of the catalyst, and the isooctanol improves the stability of the catalyst greatly. By selecting and studying the modifiers and their optimum synergistic effect, the new type homogeneous hydrogenation catalyst of benzene has been made.The catalyst has shown great advantages in activity, stability and selectivity.
