An efficient “green” modified Skraup reaction in neat water was developed using inexpensive, abundant and environmentally-friendly glycerol under microwave irradiation conditions.
Since the year 2011 Caribbean region has seen a massive seasonal influx of pelagic Sargassum. The proliferation this algae adversely affects island nations by deteriorating their coastal and marine ecosystems, like coral reefs; decreasing biodiversity, lowering water quality, while also diminishing tourism revenue, which may be economic backbone most countries in region. Sargassum seaweed its effects on Guadalupe Dominican Republic are directly linked to Sustainable Development Goal (SDG)...
A new and original high pressure reactor has been designed developed for continuous flow chemistry under microwaves at industrial scale. The originality is that the microwave applicator itself. It allows then use of metallic thick walls adapted to a pressures temperatures. Wave propagation coupled heat transfer was simulated using COMSOL Multiphysics® design optimized minimize wave reflections maximize energy transfers in reacting medium. This leads extremely good yields. Experiments confirm...
Abstract Dielectric barrier discharge (DBD) plasma technology is a promising method for producing methanol from CO 2 hydrogenation as the reaction can be run at atmospheric pressure and temperatures below 100 °C. The choice of catalyst crucial has to made not only according its activity selectivity towards desired product, but effect on properties. In this work, influence several important catalytic properties DBD such dielectric constant ionic conductivity studied. effects support addition...
Abstract Catalytic wet air oxidation (CWAO) of an aqueous phenol solution using active carbon (AC) as catalytic material was compared for a slurry and trickle bed reactor. Semi‐batchwise experiments were carried out in reactor the absence external internal mass transfer. Trickle‐bed runs conducted under same conditions temperature pressure. Experimental results from study showed that removal rate significantly increased with concentration, whereas partial oxygen pressure had little effect....
Microwave energy is used in zeolite sorption process intensification and more specifically the desorption step. To optimize a microwave process, knowledge of dielectric properties materials required. The complex permittivities several zeolites (NaA, NaK-LSX, NaX, NaY, DAYs) were measured interpreted using phenomenological models. Permittivities are linked to various such as structures (LTA FAU), number exchangeable cations, silanols density, hydration level. Three phenomena have been proven...
This paper examines the feasibility of pyrolyzing macroalgae sargassum, in a single-mode microwave cavity using char or SiC as absorber.
This paper presents an experimental study on zeolite NaX dehydration under microwave irradiation at a laboratory scale. Dehydration rates vary linearly with the absorbed power and show no influence purge gas flowrate. A pulsed mode of enhances due to higher temperatures reached improved mass transport rates. thermal balance model is developed in order assess maximum temperature adsorbent bed use dissipated energy inside solid discussed. From these results, this evaluates economic interest...
The wet air oxidation of phenol over a commercial active carbon catalyst has been studied in laboratory-scale and pilot-plant fixed-bed reactors at mild temperatures oxygen partial pressures 120−160 °C 0.05−0.2 MPa, respectively. performances the have assessed compared to each other for both up- downflow operation mode. Depending on flow mode reactor scale, distinct destruction rates observed experiments. A series batch experiments are carried out obtain removal kinetics, which subsequently...
Microwave fast pyrolysis leads to higher bio-oil production for flax shives than other biomass. An high heating rate and an optimum energy input are required maximum production. Gas oil composition is stable with operating conditions.
