  • Method for making molecular sieve SSZ-95
    Patent number: 9573124
    Abstract: A new crystalline molecular sieve designated SSZ-95 is disclosed. In general, SSZ-95 is synthesized from a reaction mixture suitable for synthesizing MTT-type molecular sieves and maintaining the mixture under crystallization conditions sufficient to form product. The product molecular sieve is subjected to a pre-calcination step, and ion-exchange to remove extra-framework cations, and a post-calcination step. The molecular sieve has a MTT-type framework and a H-D exchangeable acid site density of 0 to 50% relative to molecular sieve SSZ-32.

  • ALKYLATION REACTION USING DELAMINATED ZEOLITE SUPPORTS AS CATALYSTS
    Publication number: 20160122260
    Abstract: Provided is an improved alkylation process using a delaminated SSZ-70 catalyst. The process comprises contacting a hydrocarbon feedstock comprising olefins and isoparaffins with a catalyst comprising delaminated SSZ-70 under alkylating reaction conditions. The delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing an elimination of mass transfer in comparison with regular SSZ-70. This prevents coke formation inside zeolite channels and improves catalyst stability.
