采用铝柱蒙脱土APM和铝柱皂化土APS作为1-戊烯低聚反应的催化剂，对所需柴油产品的选择性值不同，但APM的结构导致其不能抵抗必要的再生循环。柱状皂石APS具有较弱的酸位，对柴油产物的选择性较低，但对再生处理具有很强的抗性，在重复运行中活性下降很小。催化活性结果与两种样品的酸度和结构特征有关。
An aluminum pillared montmorillonite APM and aluminum pillared saponite APS were used as catalysts for the 1-pentene oligomerization, with different values of selectivity to the desired diesel range products, but the APM structure resulted to not resist to the necessary regeneration cycles. Pillared saponite APS that is known to have weaker acid sites, was found less selective to diesel products, but resulted very resistant to the regeneration treatments with a very low decrease of activity in the repeated runs. The catalytic activity results are correlated with the acidity and with the structural characteristics of the two samples.
