The oligomerization of short alkenes (ethylene and propylene) can be used for producing commodity chemicals. Various catalysts have been used for alkene oligomerization, among which ordered microporous catalysts are thermally and mechanically stable and are already established for large‐scale industrial applications. In this work, we demonstrate ethylene oligomerization reaction on a microporous titanosilicate ETS‐10 (Engelhard Titanosiliate‐10) exchanged with Ni²⁺ (Ni‐ETS‐10). We demonstrate a template‐free and fluoride‐free ETS‐10 synthesis method that does not produce impurities commonly seen in hydrothermal ETS‐10 synthesis. Ni‐ETS‐10 showed high C₂ conversion rate, high selectivity to C₄ and high stability comparing to other microporous catalysts investigated in this work for ethylene oligomerization reaction.

在Ni‐ETS‐10上进行乙烯低聚反应以选择低聚物

短链烯烃（乙烯和丙烯）的低聚可用于生产商品化学品。烯烃低聚反应中已经使用了各种催化剂，其中有序的微孔催化剂在热和机械方面均稳定，并且已经在大规模工业应用中确立。在这项工作中，我们证明了在与Ni ²⁺（Ni-ETS-10）交换的微孔钛硅酸盐ETS-10（Engelhard Titanosiliate-10）上的乙烯低聚反应。我们展示了一种无模板，无氟化物的ETS-10合成方法，该方法不会产生水热ETS-10合成中常见的杂质。Ni‐ETS‐10表现出高的C ₂转化率，对C _4的高选择性 与本研究中用于乙烯低聚反应的其他微孔催化剂相比，具有较高的稳定性。
