Evaluation of process parameters and membranes for SO2 electrolysis
… unsafe by-products (CO2, H2S, NOx and SO2 for example) of using carbon-based fuels for energy generation have paved the way for research on cleaner, renewable and possibly cheaper alternative energy production methods. Hydrogen gas, which is considered as an energy carrier, can be …

Retrieval Advances of BrO/SO2 Molar Ratios from NOVAC
… emission at volcanoes. The emissions of BrO and SO2 can be retrieved from the recorded spectra by applying Differential Optical Absorption Spectroscopy(DOAS) and comparing the optical absorption of the volcanic plume to the background. Therefore, the background spectrum must not be affected by …

Experimental studies on the adsorption of SO2 on volcanic ashes
The adsorption of SO2 on synthetic and on natural volcanic glasses was studied. The synthetic glasses were of rhyolitic, dacitic and andesitic composition and were synthesized in a high-temperature furnace at 1600°C. The natural volcanic glasses were Lipari obsidian and Puu Waawaa obsidian. Before …

Properties and use of SO2 for the hybrid sulfur process
… discernible means to thematic interrelation. The SO2 electrolysis was performed by supplying the anode of the cell with SO2 gas, while the water was fed to the cathode using graphite plates as flow fields. Initial experimental work was done at ambient pressures on the anode (SO2 gas-fed) and …

High temperature SO2 chemisorption on model systems. Implications for in-plume processes.
… experimental techniques, this study examined SO2 scavenging mechanisms on silicate ash surfaces. SO2 uptake experiments were conducted on model Ca-aluminosilicate xerogels and on glasses with chemical compositions of common ash types. The materials were characterised using bulk and …

Atmosphärische Untersuchungen der Wechselwirkung von Mineralstaub mit den Spurengasen HNO3 und SO2
Die Spurengase HNO3 und SO2 haben Anteil an vielen klimarelevanten Prozessen in der Erdatmosphäre. Einen bislang weitgehend unerforschten Einfluss auf ihre Konzentrationen kann Mineralstaub, eines der häufigsten atmosphärischen Aerosole, haben. Im Rahmen der vorliegenden Arbeit wurde in Izana, 2367 …

A method for correlation of gravestone weathering and air quality (SO2), West Midlands, UK
… Air quality stations across the region recorded SO2 beginning in the 1960s however the direct measurement of air quality prior to 1960 is lacking and only anecdotal notations exist. Proxy records including lung tissue samples, particulates in sediments cores, lake acidification studies and …

Sulphur Chemistry in KOH-SO2 Activation of Fluid Coke and Mercury Adsorption from Aqueous Solutions
… activation was investigated. Using KOH and SO2, the activation process was able to produce SIACs with controllable specific surface area (SBET), pore size distribution and sulphur content. The highest SBET was over 2500 m2/g and the highest sulphur content was 8.1 wt%. K-edge X-ray …

Application of GIS in Visualization and Assessment of Ambient Air Quality for SO2 in Lima Ohio
… EPA recommended regulatory model) to simulate SO2 concentrations in Lima Ohio for year 2001. Model results were compared with observed values for the same year to assess the degree of representativeness of the model results. Spatial distribution of model results were shown on maps using a GIS …

The Effects of SO2 on the Formation of Cl2 During Co-Firing Muncipal Solid Waste With Coal
… resulting from the reaction between S02 and Cl2: SO2 + Cl2 + H2O → SO3 + 2HCl The effect of sulfur dioxide on the formation of chlorine through the Deacon Reaction is investigated in this study. A Lindberg Furnace was utilized and preheated to 800°C to simulate the conditions in the AFBC system. …

Observation of sulphate aerosols and SO2 from volcanic eruptions using data from the Atmospheric Chemistry Experiment (ACE)
… with a maximum age of 3 days, from enhanced SO2 concentrations and atmospheric extinction. Evidence for differences within these plumes have been obtained, showing the evolution of H2 SO4 from no sulphate aerosol signature in fresh volcanic plumes to clear signatures in aged volcanic plumes. …
