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. More deETS, please! ETS‐10 loaded with Ni2+ is shown to be active and stable for ethylene oligomerization. Ni‐ETS‐10 showed high C4 selectivity among microporous catalysts for ethylene oligomerization. [ABSTRACT FROM AUTHOR]

The Cover Feature shows the conversion of ethylene to 1‐butene on Ni‐ETS‐10 (Ni‐exchanged Engelhard Titanosilicate‐10) catalyst. The oligomerization of ethylene and propylene can be used for producing commodity chemicals, such as additives and comonomers in plastics. In their Communication, J. Thakkar demonstrate that Ni‐ETS‐10 can selectively convert ethylene to C4 alkenes with selectivity to C4 above 80%. Ni‐ETS‐10 showed high C2 conversion rate, high selectivity to C4 and high stability relative to other microporous catalysts investigated in this work. The Communication also introduces a method for synthesizing impurity free ETS‐10. More information can be found in the Communication by J. Thakkar et al. on page 4234 in Issue 19, 2018 (DOI: 10.1002/cctc.201800650). [ABSTRACT FROM AUTHOR]
