Biodiesel Processing Using Sodium and Potassium Geopolymer Powders as Heterogeneous Catalysts
(2020-06-01)
This work investigates the catalytic activity of geopolymers produced using two different alkali components (sodium or potassium) and four treatment temperatures (110 to 700 °C) for the methyl transesterification of soybean ...
Sulfonated porous carbon catalysts for biodiesel production: Clear effect of the carbon particle size on the catalyst synthesis and properties
(Elsevier Science, 2016-08)
Sulfonated porous carbons (PCs-SO3H) are prepared by the sol-gel reaction of resorcinol and formaldehyde. The porosity is maintained during drying using a cationic polyelectrolyte as pore stabilizer. It was found that ...
Glycerol-enriched heterogeneous catalyst for biodiesel production from soybean oil and waste frying oil
(Elsevier, 2015-01)
In the present work, biodiesel production using a glycerol enriched heterogeneous catalyst was studied. For that purpose, the catalyst performance at different glycerol concentrations and reaction conditions (under ambient ...
Amorphous silicates containing cerium: selective catalysts for the oxidation of cyclohexane
(Elsevier Science BvAmsterdamHolanda, 2001)
Additively manufactured geopolymer structured heterogeneous catalysts for biodiesel production
(2021-06-01)
The manufacturing of non-stochastic (lattice) scaffolds by Direct Ink Writing is attractive for catalytic fluid flow applications, as it enables the optimization of not only the desired chemically active formulation but ...
Towards a rational design of enantioselective heterogeneous catalysts: Modeling of chiral organotin precursors
(Elsevier Science, 2010-08)
In this work, the modeling of organotin compounds of general formula Men-Sn-R3 (Men=menthyl, R=alkyl or alkoxyalkyl) is carried out. These compounds can be employed as precursors for obtaining enantioselective heterogeneous ...
