  • Publication number: 20260035255
    Abstract: A method of making a molecular sieve may include: reacting a source selected from the group consisting of: a source of a tetrahedral element in the presence of a structure directing agent (SDA) selected from the group consisting of: Ar+-L-Ar, Ar+-L-Ar-L-Ar+, Ar+-L-Ar-L-NR3+, and ArAr+-L-Ar+Ar, where Ar+ is to a N-containing cationic aromatic ring, Ar is to a non-charged aromatic ring, L is a methylene chain of 3-6 carbon atoms, NR3+ is to a quaternary ammonium, and ArAr+ and Ar+Ar are a fused aromatic ring structure comprising both a N-containing cationic portion and a non-charged portion, to produce the molecular sieve.

  • Publication number: 20240368057
    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.
