Abstract
Catalysts and corresponding methods for oligomerization of olefins to distillate boiling range compounds are provided. The oligomerization can be performed in the presence of a catalyst including a 10-member ring or 1-D 12-member ring zeolitic framework material that contains both silica and alumina. The zeolitic framework material can have a low molar ratio of silica to alumina. The zeolitic framework material can be ion-exchanged to a small but substantial degree with alkaline earth metal cations, such as Mg, Ca, Sr, or Ba. The small but substantial amount of ion exchange can correspond to having a molar ratio of alkaline earth metal to aluminum of up to 0.2.
