Bifunctional noble metal/zeolite catalysts for upgrading low-quality diesel fractions via selective opening of naphthenic rings
(Royal Society of Chemistry, 2016-04-04)
Influência do método de preparação de catalisadores bifuncionais, Pt-Ni/HUSY, na isomerização do n-hexano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2008-02-25)
Gasoline containing high amount of linear chain compounds have low
octane number. However, this number can be increased when linear alkanes are
subjected to isomerization, able to change linear chain compounds to ...
Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
Synthesis of stable monodisperse AuPd, AuPt, and PdPt bimetallic clusters encapsulated within LTA-zeolites
(Academic Press Inc Elsevier Science, 2016-10)
AuPd, AuPt, and PdPt bimetallic clusters uniform in size and composition were prepared using hydrothermal assembly of LTA crystals around cationic precursors stabilized by protecting mercaptosilane ligands. The sulfur ...
Melhoria do cetano em óleo diesel : abertura do ciclo da decalina sobre catalisadores de Pt, Ir ou Rh suportados em zeólitas FAU e BEA
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-06-08)
Environmental laws and stricter quality specifications have driven the development of technologies for improving the cetane number in diesel fuel. In addition to the saturation of (poly)aromatic compounds, responsible for ...
Actividad y selectividad de Zeolitas USY modificadas y su relación con la mesoporosidad en el proceso de hidrorrompimiento catalítico
(Universidad Nacional de Colombia - Sede Bogotá, 2019-08-02)
In this work is decribed the design, construction and operation of a continuous reactor, in which hydrocracking reactions are developed, in order to evaluate the activity and selectivity of different USY zeolites. The ...
