Microwave-Assisted Depolymerisation of Biolignintm in the Presence of Zeolite-Based Catalysts
(2017-12-11)In this work a microwave-assisted depolymerisation of lignin in the presence of zeolite-based catalysts was studied in order to obtain a valuable bio-oil. Catalytic activity of H-ZSM-5, H-Y, H-BETA and H-Mordenite containing ... -
Microwave-assisted preparation of Ag/Ag2S carbon hybrid structures from pig bristles as efficient HER electrocatalysts
(Royal Society of Chemistry, 2018)Ag/Ag2S hybrid structures have recently attracted significant interest due to their high chemical and thermal stability, in addition to their unique optical and electrical properties. However, their standard synthetic ... -
Optimizing high-quality graphene nanoflakes production through organic (bio)-precursor plasma decomposition
(Elsevier, 2021)Atmospheric pressure plasma-based technique for the decomposition of biofuels allows obtaining high-quality graphene powder in one step, without the use of neither metal catalysts nor specific substrates. Despite the ... -
Stability and Activity of Zn/MCM-41 Materials in Toluene Alkylation: Microwave Irradiation vs Continuous Flow
(MDPI, 2019)Zn/MCM-41 mesoporous materials have been prepared via classic wet impregnation, employing zinc nitrate as precursor and tested for activity and stability in the Friedel-Crafts alkylation of toluene with benzyl chloride ... -
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., ... -
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, ...
