Isolation and Characterization of a SulfurOxidizing ...In a difference from other anaerobic sulfuroxidizing bacteria, this bacterium was sensitive to NaCl; growth in medium containing more than 1% NaCl was negligible. When YK1 was grown anaerobically in a sulfurdepleted inorganic medium overlaid with crude oil, sulfate was produced, corresponding to its growth. On the contrary, YK1 could not utilize crude oil as a carbon source. These results ...
In situ optical spectroscopy characterization for optimal ... · The lithium–sulfur (Li–S) battery is one of the most promising highenergydensity secondary battery systems. However, it suffers from issues arising from its extremely complied "solid–liquid–solid" reaction routes.

Characterization of SulfurContaining Compounds in ... · Molecular characterization of sulfurcontaining compounds in petroleum is of great significance for not only the oil refining but also geochemical appliion. One practical approach for the characterization is to convert nonpolar sulfur compounds into methyl sulfonium with methyl iodide/AgBF4 and to analyze them by electrospray ionization highresolution mass spectrometry. .
SELECTIVE SULPHUR FLOTATIONThe flotation method was first applied to sulphides, and then it was started to be applied oxide minerals. Different type of chemicals is used for the beneficiation of sulphide minerals. One of the most important thing in flotation is to decide the proper reagent type. Because of the similarity of surface property of sulphide minerals activator and the depressant have a crucial role. On the ...
DataDriven Approximated Optimal Control of Sulfur ...Downloadable! Sulfur flotation process is a typical industry process with complex dynamics. For a sulfur flotation cell, the structure of the system model could be derived using firstprinciples and reaction kinetics. However, the model parameters cannot be obtained under certain working conditions. In this paper, by using adaptive dynamic programming (ADP), we establish a datadriven optimal ...
