  • Selecting an improved catalyst composition and hydrocarbon conversion process using same
    Patent number: 9217735
    Abstract: The present invention provides a method for selecting an improved catalyst composition comprising a crystalline molecular sieve material having a structure and properties whereby the catalyst composition has at least one active catalytic site with a Mono Alkylation Selectivity Factor (MASF) greater than or equal to 0 kcal/mol±0.5 kcal/mol, and optionally further at least one active catalytic site with an Olefin Oligomerization Suppression Factor (OOSF) greater than or equal to 5 kcal/mol±0.5 kcal/mol. Further, there is provided an improved process for conversion of hydrocarbon feedstock in the presence of said selected catalyst composition.
    Type: Grant
    Filed: August 4, 2011
    Date of Patent: December 22, 2015
    Assignee: ExxonMobil Chemical Patents Inc.
