Fluid catalytic cracking (FCC) is one of the major conversion technologies in the oil refinery
industry. FCC currently produces the majority of the world's gasoline, as well as an important …

Microporous zeolite-type materials, with crystalline porous structures formed by well-defined
channels and cages of molecular dimensions, have been widely employed as …

The kaleidoscopic applications of zeolite catalysts (zeo-catalysts) in petrochemical
processes has been considered as one of the major accomplishments in recent decades …

The increasing environmental concern and promotion of “green processes” are forcing the
substitution of traditional acid and base homogeneous catalysts by solid ones. Among these …

ZSM-5 zeolites with different Si/Al ratios (15, 25, 40) were impregnated with phosphorus (0.5–
3 wt%) in form of H3PO4 or NH4H2PO4. The samples were characterized before and after …

This review looks at the main processes available for the production of light olefins with a
focus on maximizing the production of propylene. Maximization of propylene production has …

Alkylbenzenes form an important segment of petrochemical industry for the manufacture of
widely used commodities and specialty products. Since the last review on this topic (8) …

Catalytic cracking of butene to propene and ethene was carried out in a continuous plug-
flow stainless steel reactor over various zeolites with different pore structures and Si/Al2 …

The zeolite Beta is considered as a promising additive for FCC catalyst in diesel oil
production. In this article, it is shown that hierarchical zeolite Beta obtained by an optimized …

Despite substantial advances in crystal structure determination methodology for
polycrystalline materials, some problems have remained intractable. A case in point is the …
