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.

Abstract: Provided herein are methods for hydroisomerization of a hydrocarbon feedstock comprising contacting the hydrocarbon feedstock with hydrogen and a catalyst to yield a hydrocarbon product having an increase in branched hydrocarbons relative to the hydrocarbon feedstock. The present catalysts comprise a heteroatom-doped Beta zeolite having a trivalent cation as a framework metal oxide, an extra-framework species comprised of cerium and/or cobalt, and from 0.01 to 1.5 wt. % of a group VIII or VIB metal, or a combination thereof.
