Sensing Free Sulfur Dioxide in Wine
Sulfur dioxide (SO(2)) is important in the winemaking process as it aids in preventing microbial growth and the oxidation of wine. These processes and others consume the SO(2) over time, resulting in wines with little SO(2) protection. Furthermore, SO(2) and sulfiting agents are known to be allergens to many individuals and for that reason their levels need to be monitored and regulated in fina...
متن کاملThermocatalytic CO2-free Production of Hydrogen from Hydrocarbon Fuels
Approach • Produce hydrogen-rich gas via thermocatalytic decomposition of hydrocarbons utilizing a part of the carbon product as a catalyst for the process • Improve the catalyst activity and process efficiency by continuous activation of carbon particulates in presence of activating agents • Design, fabricate and test 3-kWth thermocatalytic reactor for CO/CO2-free production of hydrogenrich ga...
متن کاملRecent Advances in the Science and Technology of Desulfurization of Diesel Fuel Using Ionic Liquids
Sulfur-containing compounds in transportation fuels are converted by combustion to SOx, which is a major source of acid rain and air pollution [1]. For environmental protection pur‐ poses, many countries have mandated a reduction in fuels sulfur level down to 10 ppm by 2009 [2,3], and with more and more stringent regulatory constraints, it is a trend to achieve little-to-no sulfur fuels in the ...
متن کاملRapid determination of total sulfur in fuels using gas chromatography with atomic emission detection.
The purpose of this study is to determine whether gas chromatography (GC)-atomic emission detection (AED) can be used in a low-resolution mode for rapid, accurate determinations of total sulfur in fuels at trace levels to complement other popular methods of total sulfur analysis. A method for the rapid determination of total sulfur in fuels (called "fast GC-AED") is developed. The method is tes...
متن کاملDetermination of sulfur in fossil fuels by isotope dilution electrothermal vaporization inductively coupled plasma mass spectrometry
The determination of S by solution nebulization quadrupole inductively coupled plasma mass spectrometry (ICP-MS) is dif®cult because of interferences from oxygen dimer ions. The large O2 z ion current from the solvent water is a serious interference at S, the most abundant of the four isotopes, and precludes its measurement. The isotopic composition of S varies in nature as a consequence of nat...
