WebNov 10, 2024 · The catalytic conversion of ethane to ethylene by oxidative dehydrogenation provides a feedstock for oligomerisation to C4-C14 liquid fuels, the focus of the present work. Nickel supported on Siralox, a silica-doped alumina manufactured by Sasol, has been identified as a highly efficient heterogeneous ethylene oligomerization (EO) catalyst [1]. WebMar 28, 2024 · In this study, new cocatalysts are prepared by the reaction of alkylaluminums with urea and its derivatives, and successfully used to activate iron-based catalysts. It is found that the type and molar ratio of alkylaluminum and urea have significant influence on the performance of the cocatalysts.
