  • ZEOLITES, THE PRODUCTION THEREOF, AND THEIR USES FOR UPGRADING HEAVY OILS
    Publication number: 20180334390
    Abstract: According to one or more embodiments disclosed herein, a mesoporous zeolite may be made by a method comprising contacting an initial zeolite material with ammonium hexafluorosilicate to modify the framework of the initial zeolite material, and forming mesopores in the framework-modified zeolite material. The contacting may form a framework-modified zeolite material. The mesoporous zeolites may be incorporated into catalysts.

  • ZEOLITES, THE PRODUCTION THEREOF, AND THEIR USES FOR UPGRADING HEAVY OILS
    Publication number: 20180333708
    Abstract: According to one or more embodiments, a nano-sized, mesoporous zeolite particle may include a microporous framework comprising a plurality of micropores having diameters of less than or equal to 2 nm and a BEA framework type. The nano-sized, mesoporous zeolite particle may also include a plurality of mesopores having diameters of greater than 2 nm and less than or equal to 50 nm. The zeolite particles may be integrated into hydrocracking catalysts and utilized for the cracking of heavy oils in a pretreatment process.
