The direct conversion of CO2 to CO and O2 has attracted extensive attention as is a key C1 feedstock for chemical synthesis. promoted by ?-Al2O3 supported potassium intercalated g-C3N4 (KuCN/AO) catalyst in packed-bed dielectric barrier discharge (DBD) plasma system was investigated. A coaxial cylinder DBD reactor used with Cu powder the high voltage electrode. Reactor temperature showed conver...

The direct activation of diluted CO2 in argon was studied a co-axial dielectric barrier discharge (DBD) reactor powered by photovoltaic energy. influence the initial and concentration on decomposition to form CO investigated using copper-based catalyst zone. It observed that conversion higher at lower concentrations. presence diluent gas (argon) also it how has high CO2, improving At highest en...

This paper reviews ways that biomass can be converted by thermal depolymerization to make synthetic gas, i.e. syngas. Biomass, being carbon neutral, is considered as a form of solar energy stored during the growing season by photosynthesis. An effective biomass is one with low moisture and ash content, high lignin content, high calorific value, and small particle size. Woody biomass with low as...

Calculations were performed to quantify the damage parameters in the leading candidate structural and plasma facing materials when used in magnetic and inertial confinement fusion systems and when irradiated in fission reactors. The structural materials considered are ferritic steel, austenitic steel, vanadium alloy and SiC/SiC composite. Plasma facing materials included beryllium, tungsten, an...

Abstract Number densities of oxygen atoms, n O , in Ar-O 2 mixtures with small initial fractions, $${x}_{{O}_{2}}$$ x O 2 < 1%, flowing through a dielectric-barrier discharge (DBD), are calculated using plug-flow reactor model, presuming that dissoci...

Reactors based on particle suspensions for the capture, conversion, storage, and use of solar energy as H 2 are projected to be cost-competitive with fossil fuels. In light of this, this review paper summarizes state-of-the-art particle light absorbers and cocatalysts as suspensions (photocatalysts) that demonstrate visible-light-driven water splitting on the laboratory scale. Also presented ar...

The fluorescent chiral tagging reagent, 4-(3-isothiocyanatopyrrolidin-1-yl)7-(N,N-dimethylaminosulfonyl)-2,1,3-benzoxadiazole (DBD-PyNCS), was utilized for the resolution of thiol enantiomers as diastereomeric derivatives. The reagent reacts with thiol enantiomers in the presence of pyridine to produce the corresponding dithiocarbamate diastereomers under mild reaction conditions (50 °C for 40 ...

Context The CO2CRC is involved in research, development and demonstration of a number of different methods for the large scale capture of carbon dioxide. The Engineering Development Group within the CO2CRC is involved with assessing and optimization the process designs associated with the capture of CO2. The Engineering Development Group recently assessed a number of capture methods for air blo...

Odor control has gained importance for ensuring a comfortable living environment. In this paper, the authors report the experimental results of a study on the detailed characteristics of a laminated film-electrode and a laminated film-electrode packed-bed nonthermal plasma reactor, which are types of dielectric barrier discharge (DBD) reactor used for odor control. These plasma reactors can be ...

The performance of an anaerobic digestion fed with waste activated sludge (WAS) pretreated with NaOH was examined. The sludge was periodically collected from a municipal wastewater-treatment plant. The laboratory work was run in four 1-1 semi-continuous anaerobic digestion reactors. Reactor A was fed with untreated WAS at 1% total solids (TS). The other three reactors, B, C and D, were respecti...
