Pt, PtSn and PtGe catalysts supported on granular carbon for fine chemistry hydrogenation reactions
(Elsevier Science, 2008-04)
Two series of PtSn and PtGe catalysts with different metallic loadings, supported on activated carbon powder, were prepared by successive impregnation. Both the effects of the second metal addition and the Sn or Ge loading ...
Catalytic performance in citral hydrogenation and characterization of PtSn catalysts supported on activated carbon felt and powder
(Elsevier Science, 2005-03)
The liquid phase citral hydrogenation carried out at 70 °C and atmospheric pressure over Pt and PtSn catalysts supported on both activated carbon powder (C) and felt (ACf), was investigated. It was found that the addition ...
Hydrogenation of citral over ruthenium-tin catalysts
(Elsevier Science BvAmsterdamHolanda, 2003)
Ga and In promoters in bimetallic Pt based catalysts to improve the performance in the selective hydrogenation of citral
(Elsevier Science, 2015-05)
In this paper, bimetallic PtGa and PtIn catalysts supported on multiwall carbon nanotubes and carbon Vulcan were used to study the hydrogenation of citral (alpha,beta-unsaturated aldehyde) in liquid phase to produce nerol ...
Selective liquid-phase hydrogenation of citral over supported bimetallic Pt-Co catalysts
(Elsevier Science, 2009-04)
The liquid-phase hydrogenation of citral was studied at 393 K and 10 bar on Pt-Co/C catalysts, having different Pt/(Pt+Co) ratios and containing a total metal loading of about 2%. The monometallic and bimetallic Pt-Co/C ...
Highly selective synthesis of menthols from citral in a one-step process
(Elsevier Science, 2004-06)
We report for the first time the selective synthesis of menthols from citral in a one-step process. Bifunctional metal/acid catalysts active and selective for menthol synthesis were developed by studying the individual ...
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 ...
Síntesis catalítica directa de mentoles a partir de citral
(2005-08-26)
En esta tesis se estudió por primera vez la síntesis de mentoles a partir de citral, en un proceso catalítico heterogéneo de una etapa y en fase líquida, una ruta sintética novedosa, ventajosa económicamente, simple y ...
Kinetic study of the hydrogenation of citral on ir promoted au/tio2 catalyst
