Abstract: Embodiments of the disclosure include processes for selective ring-opening of cycloparaffins in hydrocarbon feeds to produce hydrocracked cycloparaffins. In particular, the process comprises contacting a hydrocarbon feed comprising cycloparaffins with hydrogen and a catalyst comprising an unsulfided, low-acidity, metal-containing zeolite under hydrocracking conditions; wherein the metal is selected from the group consisting of platinum, nickel, rhodium and mixtures thereof. The processes are useful for upgrading petroleum streams to lubricant base stocks.

Abstract: A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-114, is provided. SSZ-114 can be synthesized by treating an aluminogermanosilicate molecular sieve of CTH framework topology with water or an aqueous solution of a mineral acid under conditions sufficient to degermanate at least a portion of aluminogermanosilicate molecular sieve to form a degermanated molecular sieve and calcining the degermanated molecular sieve under conditions sufficient to convert the degermanated molecular sieve to SSZ-114. Molecular sieve SSZ-114 may be used in organic compound conversion reactions and/or sorptive processes.

Abstract: An aluminosilicate molecular sieve of STW framework type, designated herein as SSZ-110, and having a molar ratio of SiO2/Al2O3 of less than 100, is provided. SSZ-110 may be synthesized using an organic structure directing agent selected from one or more of 1,4-bis(2,3-dimethyl-1H-imidazolium)butane dications, 1,5-bis(2,3-dimethyl-1H-imidazolium)pentane dications, and 1,6-bis(2,3-dimethyl-1H-imidazolium)hexane dications. SSZ-110 may be used in organic compound conversion reactions and sorptive processes.

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.
