    摘要： The present, invention relates to a process for the production of additives for catalysts for fluid catalytic cracking (FCC) based on zeolite that is selective for light olefins, with the aim of increasing the yields, in FCC units, of liquefied petroleum gas (LPG) and light olefins, of high added value, among others propene and isobutene. This invention provides a method of preparation of catalytic compositions, starting from zeolite modified with phosphate and alkaline-earth metal, that leads to the production of an additive with better performance than the additives, of similar compositions, obtained by other methods of the prior art. The process can be regarded as a development in relation to other processes, as it promotes interaction between the zeolite that is selective for light olefins and its activator, reagent “X”. For this, a separate stage is used during the sequence of stages in the preparation. Moreover, the zeolite does not undergo additional treatments such as filtration, washing or calcination after the treatment with its activator.This additive can be obtained starting from any commercial zeolite that is selective for light olefins, such as zeolite of type ZSM-5.

    摘要： A process for preparing molecular sieves of type Y faujasite structure is described, as well as pre-shaped bodies of faujasite structure type Y molecular sieves. The process comprises preparing a precursor gel from a source of silica-alumina or a source of alumina and a source of silica with a template agent at a SiO2/Al2O3 greater than 7 and suitable for forming a type Y zeolite, drying the precursor gel and contacting the dried precursor gel with steam, optionally followed by caustic washing, without the formation of crystalline phases other than type Y zeolite being observed. Advantageously, the pre-shaped bodies prepared with the precursor gel of Y zeolite, when subjected to the process of the invention, will have their outer surface covered by type Y zeolite crystals. The molecular sieves so obtained may be employed as catalysts or adsorbents in various processes of the chemical or oil industry.
