Photocatalysis and artificial photosynthesis with octahedral main group sulphides
Jose C Conesa,, Spanish National Research Council, Spain
After a brief survey of the current need of achieving the solar energy-aided photodissociation of water, a presentation will be first made of In2S3 and SnS2 as visible light active photocatalysts. Their spectral response in a simple reaction (photooxidation of aqueous HCOOH) will be analyzed, showing the superior activity and photo corrosion resistance of these sulphides compar [....] » Read More
Design of metal-single site zeolite catalysts and their application in selective catalytic reduction of NO and oxidative dehydrogenation of propane
Stanislaw Dzwigaj, Sorbonne University, France
Abstract: The metal ions well dispersed at the zeolite framework are considered to be active sites of different catalytic processes. Therefore, the incorporation of these metals into zeolites as isolated tetrahedral sites appears to be an important task. We have shown that the incorporation of transition metal ions into vacant T-atom sites of framework zeolite is strongly favor [....] » Read More
Electricity-based processes: a new way for process intensification in chemical engineering
Eugenio Meloni, University of Salerno, Italy
The European Union, through the SET-Plan, aims to reduce greenhouse gas emissions by 20%, to have a 20% share of energy from low-carbon energy sources, and to have a 20% reduction in the use of primary energy by improving energy efficiency by 2020, with a long-term ambition to reduce emissions by 80-95% by 2050. In the way of Process Intensification, the European Commission pro [....] » Read More
Simulation of photo-bioreactors for microalgae cultivation and comparison with experimental data
Giacomo Cao, University of Cagliari, Italy
Microalgae represent renewable feedstocks for the production of a wide range of consumer goods such as biofuels, nutraceuticals, pharmaceuticals, bioplastics, functional food, lubricants for industrial applications, and feed for aquaculture systems. When compared to traditional crops, microalgae are characterized by higher photosynthetic efficiency and biomass productivity, as [....] » Read More
Fixed bed reactor and catalyst: an intimate relationship
Rafael Luis Espinoza, Espinoza and Associates, USA
In this presentation, the reaction chosen as an example is the Fischer-Tropsch reaction in a tubular fixed bed reactor. It often happens that a good catalyst is identified, but upon loading the pressure drop exceeds the design limits. There are a few ways to solve this, like decrease the reactor height, the linear velocity, the overall pressure, increase the catalyst s [....] » Read More
Parallelization of electrocatalytic oxygen evolution reactions as a new breakthrough
Heechae Choi, University of Cologne, Germany
For the commercial application of water splitting, the development of efficient electrocatalysts for water oxidation, which is a key half-reaction because of sluggish reaction kinetics, is a huge challenge. Currently, novel metal-based catalysts such as IrO2 and RuO2 are widely used for boosting water oxidation kinetics. However, the scarcity and rareness of these metals hinder [....] » Read More
Study of decomposition of Methanol over VOx/ZrO2-Al2O3 catalysts
Benomar Souhila, Polytechnic University of Valencia, Spain
Vanadium supported on pure Al2O3, pure ZrO2 or mixed zirconia-alumina catalysts have been prepared by wet impregnation, characterized by several physicochemical technical (XRD, Raman, TPD-NH3, TPR-H2, N2 adsorption) and tested in Methanol aerobic transformation. In methanol oxidation, the catalysts tested present similar catalytic activity regardless of the support (Al2O3, Z [....] » Read More
Novel nanocomposite for photonics: nickel pyrophosphate nanocrystals synthesized in silica nanoreactors
Magdalena Laskowska, Polish Academy of Sciences, Poland
Unquestionably, nanophotonics is one of the most important branches of electronics. For this reason, the search for novel and more efficient laser-operated materials seems to be fully justified. Therefore, here, we show how to fabricate materials that have an enhanced non-linear optical response using a procedure of synthesis in a silica nanoreactor. We propose doing this by a [....] » Read More
Aromatization of propane using GaAlMFI based catalyst
Muhammad Naseem Akhtar, King Fahd University of Petroleum & Minerals, Saudi Arabia
The aromatization of propane was performed over MFI-type Gallo-alumino-silicate (GaAlMFI) catalysts shaped to extrudates using nano-sized oxides (i.e. SiO2 or Al2O3). The GaAlMFI zeolites were hydrothermally synthesized having different Ga/(Ga+Al) and Si/(Ga+Al) ratios. It was observed that propane conversion and aromatic yield depend mainly on zeolite components in the case of [....] » Read More
