Mechanochemical Synthesis of TiO2 Nanocomposites as Photocatalysts for Benzyl Alcohol Photo-Oxidation
(MDPI, 2016)
TiO2 (anatase phase) has excellent photocatalytic performance and different methods
have been reported to overcome its main limitation of high band gap energy. In this work,
TiO2-magnetically-separable nanocomposites ...
Performance and Emission Quality Assessment in a Diesel Engine of Straight Castor and Sunflower Vegetable Oils, in Diesel/Gasoline/Oil Triple Blends
(MDPI, 2019)
This research evaluates the possibility of using straight oils such as castor oil, which is not suitable for food use, and sunflower oil, used as a standard reference for waste cooking oils, in blends with gasoline as ...
Microwave-Assisted Conversion of Levulinic Acid to γ-Valerolactone Using Low-Loaded Supported Iron Oxide Nanoparticles on Porous Silicates
(MDPI, 2015)
The microwave-assisted conversion of levulinic acid (LA) has been studied
using low-loaded supported Fe-based catalysts on porous silicates. A very simple,
productive, and highly reproducible continuous flow method has ...
Outlook for Direct Use of Sunflower and Castor Oils as Biofuels in Compression Ignition Diesel Engines, Being Part of Diesel/Ethyl Acetate/Straight Vegetable Oil Triple Blends
(MDPI, 2020)
Today, biofuels are indispensable in the implementation of fossil fuels replacement processes. This study evaluates ethyl acetate (EA) as a solvent of two straight vegetable oils (SVOs), castor oil (CO), and sunflower oil ...
Simple Preparation of Novel Metal-Containing Mesoporous Starches
(MDPI, 2013)
Metal-containing mesoporous starches have been synthesized using a simple and
efficient microwave-assisted methodology followed by metal impregnation in the porous
gel network. Final materials exhibited surface areas >60 ...
Continuous-Flow Processes in Heterogeneously Catalyzed Transformations of Biomass Derivatives into Fuels and Chemicals
(MDPI, 2012)
Continuous flow chemical processes offer several advantages as compared to
batch chemistries. These are particularly relevant in the case of heterogeneously catalyzed
transformations of biomass-derived platform molecules ...
Acetone Prospect as an Additive to Allow the Use of Castor and Sunflower Oils as Drop-In Biofuels in Diesel/Acetone/Vegetable Oil Triple Blends for Application in Diesel Engines
(MDPI, 2020)
The present paper investigates the feasibility of using acetone (ACE) in triple blends with fossil diesel (D) and straight vegetable oils (SVOs) as alternative fuel for diesel engines. In this respect, ACE is selected as ...
Continuous-Flow Hydrogenation of Methyl Levulinate Promoted by Zr-Based Mesoporous Materials
(MDPI, 2019)
Several Zr-based materials, including ZrO2 and Zr-SBA-15, with different silicon/zirconium molar ratios, and ZrO2/Si-SBA-15 (where SBA-15 stands for Santa Barbara Amorphous material no. 15), have been prepared as hydrogenation ...
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 ...
