Zeolitic material was synthesized from fly ash by conventional and microwave-assisted hydrothermal alkaline activation experiments. The zeolite synthesis studied as a function of temperature, time, solution concentration. K+-Na+/NH4+ exchange properties the zeolitic were time type. same changing parameters contained: NaP1, hydroxysodalite, hydroxycancrinite, analcime, tobermorite, nepheline hydrate using NaOH an agent F linde zeolite, kalsilite, phil lipsite-KM KOH activation. Synthesis...
Amine solvents are one of the main options for post-combustion CO2 capture applications. The drawback carbon processes is required energy to regenerate solvent once it has reacted with CO2. When applied a power plant, requirement an important impact on net efficiency overall system. Several solvents, i.e., monoethanolamine (MEA), diethanolamine (DEA), methyl (MDEA), and many others have been proposed overcome this drawback. Regeneration temperature heat duty reduction considered be...
A new method for the quantitative analysis of hydrogen peroxide in presence organic substances is described and discussed. The based on potentiometric titration with sodium sulphite has been successfully applied to detection quantification remaining content oxidation glycerol by H2O2. This tested: linear range covered was between 17.750 0.079 mM. standard deviation low studied (0.234–0.079 mM) 0.001 mM, limit (LOQ) obtained proposed 0.02 acidity solution showed no influence developed...
A new single walled carbon nanotubes (SWCNTs) purification procedure has been developed; it consists in a combination of air treatment and acid microwave digestion leading to high purity SWCNTs material; the reaches metal removal percentages operation time is drastically reduced compared conventional reflux treatments.
Abstract Pure zeolites can be synthesised from silica extracted fly ash by alkaline leaching. If the process is optimised solid residue arising this extraction may also contain a relatively high content of zeolitic material mixed with residual components. Both pure and impure have potential for application in waste‐water flue gas‐cleaning technologies. The 23 European coal ashes covering most possible types investigated study. Optimisation leaching processes, varying temperature, time...
This study focuses on the synthesis at a pilot plant scale of zeolitic material obtained from coal fly ashes Teruel and Narcea power plants in Spain. After optimisation parameters laboratory scale, were selected as low high glass ashes. The experiments carried out 10 m3 reactor Clariant SA (Barcelona, Spain). results allowed obtaining 1.1 2.2 tonnes with 40 55% NaP1 content, two single batch 24 8 hours, for ashes, respectively. cation exchange capacities (CEC) final product reached 2.0 2.7...
Ionic liquids (ILs) present a new alternative for postcombustion CO2 capture because their properties can be tuned by means of different cation–anion combinations in order to obtain the most suitable specific task. This work is novel study that investigates absorption kinetics and evolution chemical transformations produced ILs at temperatures. A large range pure was tested with screening process based on pKa anion efficient reversible capture. uptake selected determined wide pressures...
A description is given of several studies undertaken in the design a small, gas cell stabilized atomic frequency standard making use field-independent hyperfine resonance rubidium 87 at 6834 mc. In considered, light from vapor lamp used to enhance population differences between levels involved and also provide means detecting microwave resonance. One described concerned with generation requisite energy resonant frequency, another choice an optimum length for cell, last optimization...
