Bifunctional noble metal/zeolite catalysts for upgrading low-quality diesel fractions via selective opening of naphthenic rings
(Royal Society of Chemistry, 2016-04-04)
Selective ring opening of methylcyclohexane and decalin over Rh-Pd supported catalysts: Effect of the preparation method
(Elsevier, 2015-12)
Bimetallic Rh-Pd catalysts prepared by various impregnation methods were evaluated in the selective ring-opening of decalin and methylcyclohexane (MCH) used as model molecules of hydrogenated aromatics of the Light Cycle ...
Pt–Ir/Al2O3 catalysts for the ring opening of naphthenes. Performance as a function of time
(Springer, 2019-06)
The catalytic performance of a Pt?Ir/Al2O3 catalyst for the selective ring opening of decalin was studied as a function of time. Fresh and used catalysts were evaluated with the reaction tests of cyclohexane dehydrogenation ...
Influence of iridium content on the behavior of Pt-Ir/Al2O3 and Pt-Ir/TiO2 catalysts for selective ring opening of naphthenes
(Elsevier, 2013-02)
The influence of Ir content on the properties of Pt-Ir/Al2O3 and Pt-Ir/TiO2 catalysts for selective ring opening of naphthenes was studied. It was found that these catalysts display a strong Pt–Ir interaction but only a ...
Ru‐Pt catalysts supported on Al2O3 and SiO2─Al2O3 for the selective ring opening of naphthenes
(Wiley, 2019-11)
Alumina and silica-alumina supported Ru-Pt catalysts were evaluated for the ring opening of naphthenes. Pt, Ru and Ru-Pt catalysts were prepared by impregnation of inorganic precursors over γ-alumina and silica-alumina ...
Yield of aromatics from naphthenics upon catalytic cracking
(Sociedade Brasileira de Química, 2012-07)
Cis- and trans-decalin were reacted over cracking catalysts to study the formation of aromatics in a particular fraction of the liquid products obtained in the fluid catalytic cracking process (FCC). A batch, fluidized bed ...
Influence of Support Material on the Activity and Selectivity of Pt–Ir Catalysts for Ring Opening Reactions
(Springer, 2014-12)
The influence of the supports (Al2O3, TiO2 and SiO2) on the activity and selectivity of Pt-Ir catalysts for the ring opening of decalin was studied. It was found that the properties of the supports strongly influence the ...
Yield of aromatics from naphthenics upon catalytic cracking
(Brazilian Chemical Society, 2014)
Influence of the Brønsted acidity, SiO2/Al2O3 ratio and Rh-Pd content on the ring opening. Part II. Selective ring opening of methylcyclohexane
(Elsevier, 2014-01)
Monometallic and bimetallic Pd-Rh catalysts with various Rh/Pd atomic ratios (=0.5, 1 and 2) and a total metal charge of 1 wt% supported on SiO2-Al2O3(SIRAL 40, 20, 5) were studied for the ring opening of methylcyclohexane ...
Production of aromatic compounds in the heavy naphtha and light LCO ranges: Catalytic cracking of C10 naphthenic-aromatics and aromatics
(Wiley, 2014-11)
BACKGROUND: The conversions of bicyclic compounds, both a naphthenic-aromatic compound (tetralin) and an aromatic compound (naphthalene), as model reactants representative of the heavy gasoline and light cycle oil (LCO) ...
