dc.description.abstract Hierarchical USY zeolites obtained by scalable and affordable post-synthetic modifications (PSM) are stabilized by means of REO ion exchange and/or hydrothermal treatments, leading to FCC catalysts with improved hydrothermal stability, increased bottoms conversion capacity and improved product selectivity, as compared to a conventional commercial USY based catalyst of comparable activity. The stabilized mesoporous USY yields more and better quality diesel with a reduced content of polyaromatic compounds, while producing lower amounts of gases but with a LPG fraction enriched in propene and butenes. The obtained selectivity slate is attributed to the combination of appropriate Bronsted acidity and reduced diffusion pathway in the zeolite crystals. A detailed characterization relates the physicochemical, textural and morphological changes induced by the PSM to the resulting catalytic behavior. es_ES
