摘要： A zeolite catalyst suitable for use in shape-selective hydrocarbon conversion processes. The catalyst is modified by incorporation therein of a hydrogenation-dehydrogenation functional metal, followed by gradient selectivation with an organosilicon compound under conversion conditions, wherein the gradient selectivation conditions are characterized by a progressive temperature gradient. The use of a progressive temperature gradient during the in situ selectivation procedure unexpectedly yields a catalyst in which the hydrogenation-dehydrogenation function is stabilized, thereby enabling long duration hydrocarbon conversion processes with low by-product make.

摘要翻译： 适用于形状选择性烃转化方法的沸石催化剂。 催化剂通过加入氢化 - 脱氢官能金属进行改性，随后在转化条件下用有机硅化合物进行梯度选择，其中梯度选择条件由渐进温度梯度表征。 在原位选择过程中使用逐步温度梯度意外地产生了其中氢化 - 脱氢功能稳定的催化剂，从而使得具有低副产物的长时间烃转化过程成为可能。
