Craqueamento catalítico de 1,3,5-triisopropilbenzeno sobre catalisadores micro-mesoporosos visando a produção de hidrocarbonetos leves
(Pós-Graduação em Engenharia QuímicaUniversidade Federal de Sergipe, 2023)
Synthesis of FAU(Y)- and MFI(ZSM5)-nanosized crystallites for catalytic cracking of 1,3,5-triisopropylbenzene
(Elsevier Science, 2011-05)
Nanocrystals of FAU(Y) and MFI(ZSM5) zeolites were synthesized from clear solutions at 80-95 °C under autogen and atmospheric pressures, respectively. The X-ray diffraction (XRD) patterns confirm the structural features ...
Impact of the Desilication Treatment of Y Zeolite on the Catalytic Cracking of Bulky Hydrocarbon Molecules
(Springer/Plenum Publishers, 2015-08)
Mesoporosity was induced on a USY zeolite by means of an alkaline leaching process. Samples were immersed in 0.05, 0.10 and 0.20 M NaOH solutions during 15 min at room temperature and then were exchanged with NH4+ ions and ...
Accessibility in alumina matrices of FCC catalysts
(Elsevier Science, 2006-11)
The accessibility in aluminas considered to be representative of matrices used in FCC resid catalysts, with mean pore sizes between 64 and 201 Å, was characterized through a kinetic approach by means of the conversion of ...
Catalytic performance of silica-aluminas synthesised with the help of chitosan biopolymer
(Elsevier Science, 2009-09)
Mesoporous amorphous silica-aluminas were synthesised with standard aluminium and silicon sources by means of the formation of inorganic-organic composites with the addition of chitosan biopolymer, and compared to analogous ...
Preparação e propriedades de uma argila paranaense pilarizada com polihidroxications de alumínio

In-situ characterization of the reaction progress of the fluid catalytic cracking reactions by laser diagnostic techniques
(2019-01-14)
Sophisticated analytical techniques, such as mass spectrometry and high-performance liquid chromatography (HPLC), can be used to measure aromatic and saturate contents of the Fluid Catalytic Cracking (FCC) feedstock and ...
Vías catalíticas para maximizar la producción y mejorar la calidad del corte LCO (diesel) en el craqueo catalítico de hidrocarburos (FCC)
(2016-03-16)
Se desarrollaron prototipos de catalizadores para maximizar el rendimiento y mejorar la calidad del corte de destilados medios (LCO) en el craqueo catalítico de hidrocarburos (FCC), y mejorar el procesamiento de otras ...
Modificación y caracterización de zeolitas y por tratamiento hidrotérmico
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2019Facultad de CienciasQuímica, 2019)
Colombia and other parts of the world are experiencing problems due to the depletion of oil and its difficult extraction and refining. The use of catalytic materials such as zeolites improves the performance in the processes ...
