A new mechanistic model for molybdenum sulfide catalysts with cobalt and nickel promoters under hydrodesulfurization reaction conditions is proposed, which includes dynamic migration of sulfur and promoter atoms between adjacent sulfide layers.
The aqueous geochemistry was modeled thermodynamically for sulfide, carbonate, oxide/hydroxide, and silicate saturation and aqueous complexation versus depth with the Geochemist's Workbench geochemical code[19] and SUPCRT92 database[20] modified to include aqueous Cd-, Cr-, Fe-, MNi-,Ni-, Pb, and Zn-sulfide species, and Zn-, Cd-, and Pb-carbonate and hydroxide phases (Table 1).
Therefore, the ability and acceptable performance of using the MLP-ANN as an accurate model for estimating Hydrogen Sulfide solubility in ILs was showed versus other computational intelligence models.
Numerical modelling of sulfide oxidation indicates the maximum rate of release for sulfate, Fe, and Ni occurred shortly after tailings deposition ceased.
Models of sulfide can be used to understand the fate of sulfide during an experiment and to design experiments to maintain constant sulfide levels for providing greater clarity when interpreting experimental results.
CARMA includes formation of cloud-borne sulfate through aqueous chemistry as well as SO2 formation from dimethyl sulfide as simulated by Model for Ozone and Related chemical Tracers (MOZART) [ Emmons et al., 2010].
The IL affinity for three model VOCs (dimethyl sulfide, dimethyl disulfide and toluene) was evaluated by means of the dimensionless partition coefficient (K).
Flotation separation generally is used for sulfide ores.
The experimental results are significant for sulfide mineral engineering.
Since sulfide in liquid can be converted to volatile hydrogen sulfide (H2S), mass transfer plays a key role for sulfide loss in continuous reactors, whereas equilibrium is critical for sulfide loss in batch reactors.
