摘要
通过ＸＲＤ、脱吸附分析、ＦＴＩＲ、骨架振动红外光谱等手段表征了铝支撑酸化蒙脱土（Ｈ＋／ＡｌＺＭ）。结果表明：经酸化后的蒙脱土再进行铝交联，具有较强的固体酸性，对柴油转化为汽油和联二苯丙烯烷基化反应都有较高的催化活性。本文也讨论了固体酸对催化活性的影响。
Al pillared acid modified montmorillonites (H +/AlZM) was characterized by XRD, adsoroption desoroption measurements, FTIR and IR framework vibration spectra. It is shown that H +/AlZM has very high catalytic activity for converting diesel into gasoline and for propylene alkylation of biphenyl relative to Al pillared montmorillonites.H +/AlZM also exhibits strong surface acidity, The effect of acidity on the catalytic activities is also discussed.
