  • Publication number: 20130005565
    Abstract: This invention relates to a process of preparing a catalyst from zeolite and peptized alumina. The invention comprises adding a yttrium compound to the zeolite, either prior to, during, or after its combination with the peptized alumina. The yttrium compound can be added to the zeolite via exchange of yttrium onto the zeolite prior to addition of peptized alumina, or the yttrium can be added as a soluble salt during the combination of the zeolite and peptized alumina. In either embodiment, the zeolite catalyst is then formed from the zeolite, yttrium and peptized alumina, optionally containing other inorganic oxide. This invention is suitable for preparing fluid cracking catalysts.

  • Publication number: 20120329639
    Abstract: This invention relates to a process of preparing an improved catalyst comprising a clay derived zeolite. In particular, the invention comprises combining an yttrium compound with a zeolite produced by treating clay with a silica source and under alkaline conditions. The clay derived zeolite can be further combined with conventional matrix and/or binder precursors to form particulates suitable for use as catalysts in fluid catalytic cracking (FCC). Alternatively, the clay that is treated with the silica source and alkaline conditions can be in particulate form having sizes suitable for use in FCC, and the zeolite is produced in situ within the particulate. Yttrium compound is then combined with the zeolite in the particulate, e.g., via impregnation. It has been shown that the addition of the yttrium compound improves zeolite surface area retention, and zeolite stability in catalysts comprising clay derived zeolites.

  • Publication number: 20110224067
    Abstract: This invention comprises USY zeolite prepared by treating a USY zeolite under hydrothermal conditions after forming the USY zeolite from heat treating ammonium exchanged zeolite Y, e g, by calcination. When this invention is used in a FCC catalyst, a significant improvement of activity and selectivity in the fluid catalytic cracking (FCC) performance is observed, compared to FCC catalysts containing conventional USY zeolite. The process used to make the invention is efficient and comprises treating the USY zeolite in an exchange bath under the aforementioned hydrothermal conditions. The surface of the resulting USY zeolite has a molar ratio of alumina to silica that is higher than that seen in the bulk USY zeolite and has a unique structure as viewed by SEM and TEM.

  • Publication number: 20110163002
    Abstract: A process in which a catalytic cracking unit is operated to crack a hydrocarbon feedstock in a manner to enhance light olefin yields. The accompanying benzene-containing naphtha product stream is further processed through a benzene selective membrane to provide a low content benzene stream. Refiners frequently operate their cracking units to optimize light olefin yields, e.g. propylene, in response to needs in the petrochemical industry, and it has been discovered that units operated in this manner frequently produce naphtha containing increased amounts of benzene. The method of this invention therefore allows one to operate the unit when it is desired to optimize light olefin yields, yet at the same time produce a naphtha yield having a low benzene content. The invention is particularly useful when the cracking unit utilizes pentasil zeolites at increased concentrations to enhance light olefins yield.
