Optimization by response surface methodology of the reaction conditions in 1,3-selective transesterification of sunflower oil, by using CaO as heterogeneous catalyst
(Elsevier, 2020)In this work, the experimental conditions for the transesterification reaction of sunflower oil, over commercial calcium oxide (CaO) as heterogeneous catalysts, have been optimized employing a multi-factorial design based ... -
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., ... -
Fourth generation synthesis of solketal by glycerol acetalization with acetone: A solar-light photocatalytic approach
(Elsevier, 2021)Background: Biomass is the only renewable alternative to fossil fuels to produce chemicals. In this sense, glycerol is an important biomass-derived platform chemical obtained as a by-product during biodiesel generation. ... -
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 ... -
EPR and CV studies cast further light on the origin of the enhanced hydrogen production through glycerol photoreforming on CuO:TiO2 physical mixtures
(Elsevier, 2021)Different CuO nanoparticles were synthesized and tested in CuO:TiO2 physical mixtures for hydrogen production through glycerol photoreforming. CuO alone was inactive whereas its presence in CuO:TiO2 mixtures significantly ...
