Intracrystalline Mesoporosity over y Zeolites: PASCA Evaluation of the Secondary Cracking Inhibition in the Catalytic Cracking of Hydrocarbons
(American Chemical Society, 2017-02)
Two FCC catalyst prototypes were prepared using Y zeolite with different intracrystalline mesoporosity, which were used in the cracking of n-hexadecane (batch fluidized bed reactor, reaction time 4 s, temperatures 500 and ...
Three-dimensional modeling of fluid catalytic cracking industrial riser flow and reactions
(Pergamon-elsevier Science LtdOxfordInglaterra, 2011)
Comparações microbiológicas de indivíduos expostos e não expostos ao crack
(Universidade Federal de Santa MariaBROdontologiaUFSMPrograma de Pós-Graduação em Ciências Odontológicas, 2015-07-07)
Several risk factors have been shown to be able to adjust the establishment and progression of periodontal disease. There is evidence demonstrating that some illegal drugs like cocaine and heroin can influence the pathogenesis ...
Screening of optimal pretreatment and reaction conditions for the isomerization-cracking of long paraffins over Pt/WO3–ZrO2 catalysts
(Elsevier Science, 2010-10)
Pretreatment and reaction conditions for the isomerization-cracking of long paraffins over commercial Pt/WO3-ZrO2 catalysts were screened. Optimal conditions were seeked for the production of short, high octane branched ...
Cracking due to alkali-silica reaction in slab at the Jaguari hydroelectric power plant - A qualitative studyesEstudio cualitativo sobre fisuración debida a la reacción álcali - sílice en el forjado de la represa hidráulica de Jaguari
(2013-01-01)
The concrete structures of Jaguari Hydro Power Plant (HPP) display cracks due to the occurrence of Alkali-Silica Reaction (ASR). The qualitative analysis of the cracks that occur in the slab of the water intake structure ...
Kinetic study on catalytic cracking of Brazilian high-boiling-point petroleum fractions
(SpringerDordrechtHolanda, 2012)
Synergy in the Cracking of a Blend of Bio-oil and Vacuum Gasoil under Fluid Catalytic Cracking Conditions
(American Chemical Society, 2016-02)
The catalytic cracking of a blend of raw bio-oil (20 wt %) from black poplar sawdust fast pyrolysis and vacuum gasoil (VGO, 80 wt %) has been studied. The runs have been performed in a riser simulator reactor (RSR) under ...
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 ...
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 ...
