Advanced Biofuels from ABE (Acetone/Butanol/Ethanol) and Vegetable Oils (Castor or Sunflower Oil) for Using in Triple Blends with Diesel: Evaluation on a Diesel Engine
(MDPI, 2022)From a technical and economic point of view, our aim is to provide viable solutions for the replacement of fossil fuels which are currently used in internal combustion diesel engines. In this research, two new biofuels ... -
Advances in nanocatalysts design for biofuels production
(Wiley-VCH, 2017)The exploitation of nanocatalysts, at the boundary between homogeneous and heterogeneous catalysis, is tracking new efficient ways to produce renewable biofuels in environmentally friendly conditions. Their solid state ... -
Aldol Condensation of Furfural with Acetone Over Mg/Al Mixed Oxides. Influence of Water and Synthesis Method
(MDPI, 2019)Aldol condensation of furfural and acetone (an important initial step to obtain diesel from biomass) was studied over MgAl mixed oxides. The influence of the utilization of microwaves and/or a surfactant (Pluronic 123) ... -

An Efficient and Recyclable Nanoparticle-Supported Cobalt Catalyst for Quinoxaline Synthesis
(MDPI, 2015)The syntheses of quinoxalines derived from 1,2-diamine and 1,2-dicarbonyl compounds under mild reaction conditions was carried out using a nanoparticle-supported cobalt catalyst. The supported nanocatalyst exhibited ... -
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 ... -
Análisis arqueométrico de los productos de corrosión de un caldero de bronce de baja época ibérica del Cerro de la Cruz (Almedinilla, Córdoba)
(Museo Histórico Municipal de Priego de Córdoba, 2017)Se estudian una serie de fragmentos de bronce de época ibérica hallados en el Cerro de la Cruz (Almedinilla, Córdoba) para determinar la composición química de los productos de corrosión formados sobre ellos. La caracterización ... -

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 ... -
Archaeometric identification of a perfume from Roman times
(MDPI, 2023)Although archaeological excavations have recovered a large number of vessels used to hold perfumes or ointments in ancient Rome, little is known about the chemical composition or origin of the substances they contained. ... -
Artificial Coal: Facile and Green Production Method via Low-Temperature Hydrothermal Carbonization of Lignocellulose
(ACS, 2022)A new concept is proposed for the production of artificial coal under HTC conditions using Mg(NO3)2 as an oxidant in a short time, which is found to enhance the coalification degree of hydrochar from lignocellulosic ... -
