Abstract: Provided is an improved process for olefin oligomerization allowing one to realize superior selectivity. The process comprises contacting a hydrocarbon feed comprised of straight and branched chain olefins under oligomerization conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing for elimination of mass transfer in comparison with regular SSZ-70. The result is superior selectivity.

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.
Abstract translation: 提供了使用脱层SSZ-70催化剂的改进的烷基化方法。 该方法包括在烷基化反应条件下使包含烯烃和异链烷烃的烃原料与包含脱层SSZ-70的催化剂接触。 分层SSZ-70在一个维度上提供了具有单个单元电池单元的沸石层，与常规SSZ-70相比，可以消除传质。 这防止了沸石通道内的焦炭形成，并提高了催化剂的稳定性。
