Application of Enzymatic Extracts from a CALB Standard Strain as Biocatalyst within the Context of Conventional Biodiesel Production Optimization
(MDPI, 2017)
The application of biocatalysts in the transesterification process of triglycerides (TG) allows
integrating the glycerol in the form of monoglyceride (MG), sharply increasing the yield and the
environmental sustainability ...
Hydrogen Photo-Production from Glycerol Using Nickel-Doped TiO2 Catalysts: Effect of Catalyst Pre-Treatment
(MDPI, 2019)
In the present piece of research, hydrogen production via the photo-reforming of glycerol (a byproduct from biodiesel generation) is studied. Catalysts consisted of titania modified by Ni (0.5% by weight) obtained through ...
A Biofuel Similar to Biodiesel Obtained by Using a Lipase from Rhizopus oryzae, Optimized by Response Surface Methodology
(MDPI, 2014)
A new biodiesel-like biofuel is obtained by the enzymatic ethanolysis reaction
of sunflower oil with ethanol, in free solvent media, by using BIOLIPASE-R, a
multipurpose alimentary additive from Biocon®-Spain that is a ...
An Overview of the Production of Oxygenated Fuel Additives by Glycerol Etherification, Either with Isobutene or tert-Butyl Alcohol, over Heterogeneous Catalysts
(MDPI, 2019)
Biodiesel production has considerably increased in recent decades, generating a surplus of crude glycerol, which is the main drawback for the economy of the process. To overcome this, many scientists have directed their ...
Sulfonic Acid Functionalization of Different Zeolites and Their Use as Catalysts in the Microwave-Assisted Etherification of Glycerol with tert-Butyl Alcohol
(MDPI, 2017)
The etherification of glycerol with tert-butyl alcohol in the liquid phase, over different
sulfonic acid functionalized zeolites, has been studied. The reaction was carried out using
microwaves as a way of heating, ...
Glycerol and Catalysis by Waste/Low-Cost Materials—A Review
(MDPI, 2022)
The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, for example. The most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain ...
Sulfonated carbons from olive stones as catalysts in the microwave-assisted etherification of glycerol with tert-butyl alcohol
(Elsevier, 2020)
Sulfonated carbons have been prepared from an important waste in Andalusia, the olive stones. The sulfonic acid groups incorporation has been made by sulfuric acid treatment and different conditions have been tested, i.e., ...
Glyceraldehyde production by photocatalytic oxidation of glycerol on WO3-based materials
(Elsevier, 2021)
Valorization of glycerol into high added-value products by photocatalysis can not only create good economic benefits, but also cater to the global low-carbon and energy-saving environmental protection needs. In this study ...
Hydrogen photoproduction on TiO2-CuO artificial olive leaves
(Elsevier, 2021)
Olive leaves were used as biotemplates to synthesize diverse TiO2-CuO solids. A successful replication of trichomes and internal channels was evidenced by SEM, whereas a good dispersion of Cu and Ti atoms was observed by ...
Sulfonated organosilica-aluminum phosphates as useful catalysts for acid-catalyzed reactions: Insights into the effect of synthesis parameters on the final catalyst
(Elsevier, 2022)
The synthesis, by a sol-gel method, of organosilica-aluminum phosphates, (X)-AlPO(Y)-(Z), using three different silica precursors (X) 2-(4-chlorosulfonylphenyl)ethyltrimethoxysilane (C), 3-(mercaptopropyl)trimethoxysilane ...
