Rhizomucor miehei Lipase Supported on Inorganic Solids, as Biocatalyst for the Synthesis of Biofuels: Improving the Experimental Conditions by Response Surface Methodology
(MDPI, 2019)
Two inorganic solids have been evaluated as supports of Lipozyme RM IM, a Rhizomucor miehei lipase immobilized on a macroporous anion exchange resin, in order to improve its application as a biocatalyst in the synthesis ...
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, ...
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., ...
Optimization of Biodiesel and Biofuel Process

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 ...
Probing the pyrolysis process of rice straw over a “Dual-Catalyst Bed” for the production of fuel gases and value-added chemicals
(MDPI, 2023)
Rice straw is an agricultural byproduct primarily produced in Asian regions. It is crucial to discover an effective method for converting this waste into chemicals that can be utilized to substitute goods derived from ...
Internal combustion engines and carbon-neutral fuels: a perspective on emission neutrality in the European Union
(MDPI, 2024)
Nowadays, there is an intense debate in the European Union (EU) regarding the limits to achieve the European Green Deal, to make Europe the first climate-neutral continent in the world. In this context, there are also ...
Biochars from olive stones as Carbonaceous support in Pt/TiO2-Carbon Photocatalysts and application in hydrogen production from aqueous glycerol photoreforming
(MDPI, 2023)
Several biochars were synthesized from olive stones and used as supports for TiO2, as an active semiconductor, and Pt as a co-catalyst (Pt/TiO2-PyCF and Pt/TiO2-AC). A third carbon-supported photocatalyst was prepared from ...
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 ...
Controlled photodeposition of Pt onto TiO2-g-C3N4 systems for photocatalytic hydrogen production
(Elsevier, 2022)
Platinum (0.5 wt. %) was photodeposited on g-C3N4-TiO2 systems using UV or Vis light. Different absorption by semiconductors seemed to somehow influence resulting platinum particle size and distribution. Thus, lower platinum ...
