Transformación de glicerol mediante catalizadores heterogéneos ácido-básicos y metálicos soportados en diferentes ambientes redox
(Universidad de Córdoba, UCOPress, 2016)
1. Introducción o motivación de la tesis
Durante las últimas décadas, los investigadores han dirigido sus
esfuerzos hacia la protección del medio ambiente y al desarrollo de procesos
sostenibles con el entorno [1,2]. ...
Utilización de lipasas en la producción de un nuevo tipo de biodiesel que evita la generación de glicerol
(Universidad de Córdoba, Servicio de Publicaciones, 2012)
Los altos precios de los combustibles derivados del petróleo están ocasionando una intensificación de la investigación de los métodos de producción de los biocombustibles, con la idea de optimizar la producción de combustibles ...
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 ...
Synthesis, Performance and Emission Quality Assessment of Ecodiesel from Castor Oil in Diesel/Biofuel/Alcohol Triple Blends in a Diesel Engine
(MDPI, 2019)
This research aims to promote the use of second-generation biofuels based mainly on Castor oil, which is not adequate for food use, and Sunflower oil as a standard reference for recycled oils. They have been applied in the ...
Biodiesel at the Crossroads: A Critical Review
(MDPI, 2019)
The delay in the energy transition, focused in the replacement of fossil diesel with biodiesel, is mainly caused by the need of reducing the costs associated to the transesterification reaction of vegetable oils with ...
Enzymatic Production of Ecodiesel by Using a Commercial Lipase CALB, Immobilized by Physical Adsorption on Mesoporous Organosilica Materials
(MDPI, 2021)
The synthesis of two biocatalysts based on a commercial Candida antarctica lipase B, CALB enzyme (E), physically immobilized on two silica supports, was carried out. The first support was a periodic mesoporous organosilica ...
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 ...
Biodiesel Is Dead: Long Life to Advanced Biofuels—A Comprehensive Critical Review
(MDPI, 2022)
Many countries are immersed in several strategies to reduce the carbon dioxide (CO2) emissions of internal combustion engines. One option is the substitution of these engines by electric and/or hydrogen engines. However, ...
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 ...
Biofuel that Keeps Glycerol as Monoglyceride by 1,3-Selective Ethanolysis with Pig Pancreatic Lipase Covalently Immobilized on AlPO4 Support
(MDPI, 2013)
By using pig pancreatic lipase (EC 3.1.1.3 or PPL) as a biocatalyst, covalently
immobilized on amorphous AlPO4 support, a new second generation biodiesel was
obtained in the transesterification reaction of sunflower oil ...
